The Switch from Atrenta to Real Intent for CDC, Lint, and X-prop

Graham Bell   Graham Bell
   Vice President of Marketing at Real Intent

John Cooley’s web-site likes to publish end-user experience with various EDA tools.  On May 6, he published a posting on why a designer switched from Atrenta SpyGlass to Real Intent for CDC, Lint, and X-propagation analysis.  His report details the reasons for converting to our best-in-class tool suite.

Here is the first part of the posting:

We had been using SpyGlass from Atrenta, and it worked OK for us, but we
were told by our local Real Intent sales guy that “there would be fewer
iterations for Lint, easier setup for CDC, lower-noise reporting, and
faster runtimes” — if only we evaled his tools.


I spent one work week (5 days) evaluating Meridian CDC. We used different
designs to evaluate this tool. The first was 850K gate design that had
3 asynchronous clock domains. For the analysis setup, Meridian CDC
automatically detected all the clock/reset candidates correctly at block-
level as well as the top-level. No additions were needed for the setup
file, while our Spyglass run did require manual editing of the setup.
The Meridian runtime for this block was ~5 minutes.

The second design was 4 million gates and had 5 asynchronous clock domains.
Again the automatic clock/reset detection worked as expected. The runtime
was ~15 minutes.

Read the rest of the report on CDC, lint and X-propagation here.

Have you switched EDA tools recently?  How was that experience?

May 17 Event: More than Moore – Enabling the Power of System Scaling

Graham Bell   Graham Bell
   Vice President of Marketing at Real Intent

More than Moore – Enabling the Power of System Scaling:
An Open Discussion About Design and Manufacturing Challenges

Join the ESD Alliance on the evening of May 17th at 6PM when we will be hosting an open dialogue about system scaling solutions and what it will take to propel them into the mainstream for semiconductor design and manufacturing. Although various system scaling technologies (such as interposer-based designs, using die-level IP blocks, like HBM) are already in use today, they have not yet crossed into the mainstream.

MultiChip Module

System scaling offers an excellent alternative path to pursuing Moore’s Law by moving the integration focus from the transistor to the integration of several heterogeneous pre-fabricated and proven devices, in the form of die-level IP, into an advanced IC package. Although new sub- 10nm process technologies continue to drive Moore’s Law, development cost and times at these advanced nodes are beyond the reach of much of the mainstream market.

It will take collaboration and cooperation between modeling, design, analysis/verification, manufacturing and test in order to unlock the potential of these new integration solutions. The objective for the meeting is to have an open discussion to identify the highest priority issues that should be jointly worked on to streamline the path to widespread adoption. The ESD Alliance is in the process of forming a working group representing both manufacturing and design to work on practical solutions and is seeking community input on direction and priorities.

This is an open event and we encourage anyone who is involved with or interested in system scaling from either the design or manufacturing perspective to attend. Please join us at 6 pm for networking, food and beverages prior to the open discussion forum, starting at 6:30.

7 Design Faults Leading to Clock and Data Glitches

Graham Bell   Graham Bell
   Vice President of Marketing at Real Intent

Recently I came upon an article by Ankush Sethi of Freescale on the importance of avoiding bad design practices that lead to glitches in clocks which result in asynchronous behavior. He points out:

It is very important to make digital designs free of any clock or data glitches to ensure correct functioning. There are many cases where such issues have caused functional failure, or increased design time through incurring extra debug effort. Hence, it is very important for a designer to take care of such issues at the earliest stages of design once flagged by a tool or gate-level synthesis.

Here is his introduction followed by an iframe of the article from EDN magazine.

With the increasing complexity of SoCs, multiple and independent clocks are essential in the design. The design specifications require system level muxing of some of these clocks before they are sent to actual IP. Also, to save power, clock gating cells are inserted in clock paths. While implementing these muxing and gating cells, a designer tends to make mistakes that can lead to glitches. A glitch on a clock signal exposes a chip (or a section of a chip) to asynchronous behavior. A glitch-prone clock signal driving a flip-flop, memory, or latch may result in incorrect, unstable data. This paper discusses structural faults that can lead to glitches in clocks. Also, some bad design practices that lead to glitches in data are discussed.

UPF 3.0 – Making Power Intent Manageable, Incremental and Executable

Vinod Viswanath  Vinod Viswanath

UPF provides a consistent format to specify power design information that may not be easily specifiable in a design description. In certain situations it is undesirable to specify power semantics directly in the HDL, as doing so might tie down the implementation to certain power constraints. UPF provides a way to specify the power intent for different states and contexts, external to the design, to be used for implementation, modeling, simulation and verification. The semantics of UPF are consistent across implementation and verification, guaranteeing that what is being verified is indeed what was implemented.

UPF assumes a logical hierarchy that is a more abstract model of the design hierarchy. The logical hierarchy can be viewed as a conceptual structure for locating power management objects such as power domains and power states. Each object is defined in a specific scope of logical hierarchy. This logical hierarchy can be effectively used in a top-down UPF methodology, where the more abstract states are higher up in the hierarchy (global states), and the lower hierarchical objects are more refined versions of their ancestors.

Such a top-down methodology is actually very close to current SoC design methodology. Previous designs done in-house or via third-party IP are extensively used in SoC design today to reduce development cost and time to market. To manage these IP-based flows, most SoC designs are implemented with hierarchical top-down design flows. Given the complexity of design analysis, hierarchical design flow also allows a way to overcome capacity limitations of design and verification tools. A top-down UPF flow fits seamlessly with this approach. The tricky part comes with the IP blocks. The power intent specification for an IP block to be used in a larger design typically defines the power interface to the block and the power domains within the block. This specification also typically includes constraints on using the block in a power-managed environment. The IP block UPF, which contains the atomic power domains, power states, and the state transitions of the IP block, is often referred to as a constraint UPF. When the IP is being prepared for use in a larger system, the specification can be enhanced to fit the context of the system (for example, it may require adding isolation and retention strategies). The power specification with this context information is referred to as the configuration UPF. Finally, to drive the implementation, we may have to define power distribution network information, logic for the power management cells, etc. This specification is referred to as the implementation UPF.

Once the UPF hierarchy is set up, UPF provides commands to specifying retention strategies, repeater strategies, isolation strategies and level-shifting strategies. Each of these can be defined in various ways to apply specific design features, with precedence orders in cases where multiple strategies apply to the same feature, etc.

While implementing a system, occasionally it might be necessary to implement an instance separately from the top-level scope, with the intention of integrating this block back into the system later in the flow. This flow style is a bottom-up flow. When using a bottom-up flow, the UPF partitioning has to ensure that the implementation of the lower-level instance can be done without the parent scope being available. Self-contained UPF is UPF that defines its own top-level domain and does not require power intent to be defined in any external scope to complete the power intent.

In system level design simulations, faster run times are generally attained via design abstraction. In order to extend this analysis to accommodate power, we have to annotate power information onto this simulation. UPF provides system-level IP power models for exactly this purpose. The power models are intended to be used in system-level design, although, there is nothing to prevent their use in other types of analysis at all levels of design abstraction. From the standard perspective, modeling all types of IP components is supported with no limitations on use. The IP power model cannot make any changes to the state of the system.

Specifically in the 2015 standard, the UPF power state supports a model (-model) and a power function (-pwrfn) switch to support modeling as well as refinement. Power function of a “current” power state is the natural function to use for power computations at that state. More refined power states would have more detailed power functions.  The power model contains an enumeration of all the power states, power consumption data for each, and a definition of all legal power state transitions.

Even with all these power models, the larger problem remains unaddressed. Today, when SoCs are optimized for specific applications, the optimizations are done in isolation without utilizing the knowledge of the workloads. Due to lack of hardware/software cooperation in power management, the platform as a whole cannot anticipate power requirements of the application ahead of time and, instead, has to perform power management reactively.

Going forward, it is quite clear that neither hardware nor software in isolation can make the best decision about power and performance management, and cannot just manage the CPU alone, but must now include the entire platform level, in a holistic way.  Any such holistic approach needs a common representation of power intent at all levels of design hierarchy, and power management engines at each level need to make decisions based on the unified set of power constraints. It is imperative that a holistic platform-level dynamic power management system be aware of (a) different power states supported by different components, both at architectural and microarchitectural level; (b) current power consumption of the platform as a whole, and at the individual component level; (c) power requirements of applications and workloads; and (d) continuous feedback from the platform on performance with respect to overall power constraints. We need a synergistic bottom line across RTL, System level, OS level, Compiler level, and Application level specifications of power intent. The kind of information available at a higher level of abstraction at the OS level or even at the Application level is just not visible to the RTL. To get the most optimized solution,we need all levels of abstraction of the design to be able to communicate their power intent.

This leads to a new set of abstractions all along the design and application hierarchies, the power abstraction. At the workload level, the application needs to specify what kind of power requirements it has. This translates to compiler level constraints and then O/S constraints and so on all the way to the RTL and gate-level designs. There are two new requirements on such a system:. (1) We need feedback going up the abstraction levels. The hardware needs to let the O/S know how it is performing, power-wise and so on. (2)We need a fast and dynamic constraint solver/power manager that can combine the feedback with the spec to generate the next set of optimizations.

Key to all this coming together is a standard way to communicate across these levels of energy abstractions. IEEE Standards Association is addressing this via three ongoing standards efforts – IEEE 1801 (system power), IEEE P2415 (power specification in software and O/S), and IEEE P2416 (power modeling).

Beyond this, thermal considerations cannot be handled in isolation either. The objective of thermal management is to meet “maximum operating temperature” constraints, while maintaining performance requirements. Typically thermal control policies manage power consumption via dynamic frequency and voltage scaling (DVFS) and can be targeted to power density reduction because it has the effect of reducing overall temperature. Thermal control policies using DVFS avoid violations of temperature bounds by transitioning processors into low power modes to cool down, but obviously this incurs a performance penalty. In addition, abrupt power mode transitions due to DVFS could also waste power.

How Physical Implementation Can Break Your Clock-Domain Crossing Logic

Graham Bell   Graham Bell
   Vice President of Marketing at Real Intent

At DVCon’16, Mark Litterick presented a paper and presentation on “Full Flow Clock Domain Crossing – From Source to Si.”   Here is the abstract for the paper:

Functional verification of clock domain crossing (CDC) signals is normally concluded on a register-transfer level (RTL) representation of the design. However, physical design implementation during the back-end pre-silicon stages of the flow, which turns the RTL into an optimized gate-level representation, can interfere with synchronizer operation or compromise the effectiveness of the synchronizers by eroding the mean time between failures (MTBF). This paper aims to enhance cross-discipline awareness by providing a comprehensive explanation of the problems that can arise in the physical implementation stages including a detailed analysis of timing intent for common synchronizer circuits.

Mark works for Verilab as senior verification consultant and holds the position of fellow. He is based in Munich, Germany.  To see more of Mark’s technical papers, check out his profile page on the Verilab web-site.

Even though, you may have signed-off for CDC at RTL, logic synthesis, design-for-test and low-power optimization tools can break CDC at the gate-level, the physical implementation stage of design. Real Intent’s Meridian products provide clock-domain crossing verification and sign-off.  Our most recent offering is Meridian Physical CDC and provides sign-off at the netlist level of the design.  It uses a mix of structural and formal methods to identify  glitching and other errors that break the correct registration of signals crossing clock domains.

At this link are the slides for Mark’s presentation.  I have reproduced one of the them for you to outline the specific issues that can compromise CDC at the gate-level .


At this link is the technical paper that discusses the issue in detail and the pitfalls for different synchronizer approaches. It is worth looking at.

In his conclusion, Mark states:

The  main  advantage  of  running  CDC  analysis  on  the final  netlist  (as  well  as  the  RTL  sign-off  stage)  is  to  pick  up  additional  structural  artifacts  that  were introduced  during  the  back-end  synthesis  stages  such  as  additional  logic  on  CDC  signal  paths  that  might result in glitches, and badly constrained clock-tree synthesis which could for example destroy an intended derived  clock  structure.  The  tools  use  the  same  fundamental  clock  domain  and  synchronizer  protocol descriptions as the RTL phase and can therefore assess if some high-level intent has been compromised.

His last word is:

Finally, we would recommend a methodology which involves an explicit dedicated  CDC and synchronizer review as part of the final pre-silicon sign-off criteria prior to tape-out.

Physical implementation of RTL designs can break the logic for CDC of signals.  A gate-level sign-off for CDC is necessary for modern SoCs or chip failures will be occur in production parts.

Informal, Unformal, or Appformal? …and new

Graham Bell   Graham Bell
   Vice President of Marketing at Real Intent

Around the Design and Verification Conference in San Jose at the beginning of the March, a lot of activity was happening in the online world in preparation for the big meetup of the verification community.

First, the web-site published a set of five (5) articles that surveyed the world of formal verification in EDA, written by Jim Hogan, of Vista Ventures, a Silicon Valley investment firm.  Jim is currently on the Board of OneSpin, a formal tools company.  Knowing Jim, he did his homework before getting involved with them.  If you read the articles, which total 12,000 words, you will have to agree with me there is a lot of great content here.  If a technical writer charged for producing this, you would be looking at a bill close to $20,000.

These days you have to two general ways to verify the functionality of your RTL with formal.  You either write your own properties and then feed them and the RTL to a formal property verifier (FPV) tool, OR you have an application-focused formal tool  automatically read and apply properties to your design.

In the early days of Real Intent we had our own FPV tool.  However, by the late 2000’s we realized that designers needed specific solutions to verification problems.  And so instead of attacking the general verification market, we focused on clock-domain crossing verification, and automatic code-checks for common RTL problems with FSMs, dead-code, etc.  This lead to our existing suite of Meridian and Ascent products which cover five (5) different categories.

In the fourth article by Jim, “16 Formal Apps that make Formal easy for us non-Formal engineers“, Jim uses the “apps” moniker to identify this category.  Our CTO, Pranav Ashar, takes exception to this term.  In his view, “app” has been subverted to convey a pejorative sense as in “It is just an app!”  It has become something to download to your phone to use without a second thought, and with a corresponding low value.

Our Meridian clock-domain crossing sign-off tool fits into the CDC app category, but there is a substantial amount of software technology under-the-hood to make it effective for a wide-range of designs.  If CDC is an “app” so is static timing analysis (STA). But nobody calls STA an “app”!

Perhaps this new category of problem-focused formal applications, which are easy to use, need a different label.  Since these new formal tools are targeted to ordinary engineers and not PhD’s,  perhaps we could call these solutions “informal”, “unformal” or even “appformal”.

What do you think?

Second, a new web-site called has just been launched. It is an open and free community, and anyone interested in Formal Verification is invited to post relevant and useful information, or write a blog.  It is intended to make it easy to explore and learn about formal, as well as to share experience and research with others.  It is sponsored by OneSpin but has pointers and content for all the formal verification suppliers, including Real Intent. OneSpin “will take a hands-off role in its management.”

The site is managed by Jan Kuster, an independent consultant. Contact Jan Kuster with content suggestions or ideas at

I looked around the site and I guarantee you will see something that will interest you.

I did read the blog post by Elchanan Rappaport of Gila Logic.  Titled “Formal Evaluations, or the Fine Art of Shooting Yourself in the Foot” it gives a real world experience of introducing a FPV tool to a company and what trouble can arise.  A great balance to Jim’s articles, I recommend everyone considering a FPV tool to read it and learn from other’s experience.

DVCon Recap

Graham Bell   Graham Bell
   Vice President of Marketing at Real Intent

The Design and Verification Conference in Silicon Valley delivered the goods again this year. Here are some quick highlights from the show.

Graham talking to Koko and Pippa at the Oski Tech booth.

Graham talking to Koko and Pippa at the Oski Tech booth.

Wally Rhines, Chairman and CEO of Mentor Graphics gave another engaging, informative and amusing keynote presentation.  Wally took us down through the years with his talk titled “Design Verification Challenges: Past, Present and Future.”  Here is the summary slide of Wally’s presentation that captures the major ideas of his talk.


On Tuesday evening, Jim Hogan spoke with Ajoy Bose, former CEO of Atrenta, on his career building multiple businesses in the technology industry.  He started with AT&T and then later on founded Interra which led to the inception of Atrenta and the SpyGlass product.  He mentioned the importance of two mentors in this success. I know only some small pieces of Ajoy’s story and found his history to be in many ways the history of Silicon Valley.  Ajoy’s one-on-one with Jim was video recorded, and will be available in the near future on the EDA Consortium web-site.

On Wednesday were two conference panel and a sponsored lunch panel by Cadence.  The first panel on “Redefining ESL” certainly exposed the reality that ESL (Electronic Systems Level) is not just 4 0r 5 technology components but more like 15 or more.  This makes the transition from Gate-level to RTL design which involved just a small set of technologies much less daunting that the transition from RTL to ESL design.  Panelists from the EDA companies said we are getting there is incremental steps.  Those in the audience at the microphone pushed for an even wider definition of ESL.  This panel was also video recorded and will be available at a future date.

The sponsored lunch panel was on the topic “Software Driven Verification with Portable Stimulus: The Next Productivity Leap Enabling the Continuum of Verification Engines.”  Frank Schirrmeister of Cadence Design Systems was host and presented how the new portable stimulus standard will be useful in keeping different verification working with maximum efficiency by using a high-level stimulus definition.  The panel was also video recorded and will be available at a future date.

In the afternoon on Wednesday was the panel sponsored by Real Intent and hosted by Jim Hogan: “Emulation + Static Verification Will Replace Simulation.”  At the beginning it seemed all the panelists were in agreement that we were not going to replace simulation. Panelist Brian Hunter from Cavium was particulary adamant that this was the case and necessary for clearing maximum bugs at lowest cost.  Lauro Rizzatti, a verteran emulation executive, made his pitch that we should be using more emulation and that it is the most cost effective way to get to design sign-off.  Pranav Ashar make the point only static verification can handle some of the problems facing design teams, and used the example of CDC verification.  This panel was also video recorded and will be available at a future date.

The next DVCon events are in India and Europe in September and October respectively.  I am sure they will be engaging and informative as our Silicon Valley event was this week.
