Real Intent Unveils Debug Enhancements in New Version of Ascent IIV for Static Verification of Digital Designs

Real Intent Unveils Debug Enhancements in New Version of Ascent IIV
for Static Verification of Digital Designs

SUNNYVALE, Calif. – July 22, 2014

Real Intent, Inc., a leading provider of EDA software products today announced a new version of its Ascent Implied Intent Verification (IIV) tool for static functional analysis of digital IC designs, delivering new debug enhancements for users. Ascent products find elusive bugs and eliminate sources of uncertainty that are difficult to uncover using traditional Verilog or VHDL simulation, leading to both improved QoR and productivity of design teams.

New Ascent IIV features and enhancements include:

  • Specialized report categories for FSMs, language checks, design checks, coverage, and X-verification with control of report depth for easier debug review
  • Causality reporting, which shows the secondary errors caused by each primary error so designers can rank the impact of fixing primary errors
  • New language checks for violations of SystemVerilog constructs – unique, priority, and enumeration
  • Easier setup for quick adoption
  • 15 other analysis and debug improvements

Lisa Piper, senior manager of technical marketing at Real Intent, said, “IIV‘s root cause analysis dramatically reduces debug time by focusing the effort on the real design problems, without the distraction of related secondary issues. Our new specialized reports make it easier for designers to focus on categories of concern, tailor the results, and see the impact of fixing primary errors. For the first time, IIV now has checks for SystemVerilog constructs that are not in classic Verilog code. Our Ascent products remain the fastest and highest-capacity static verification solutions available for uncovering issues prior to digital simulation.”

The latest release of Ascent IIV will be available on July 28 for download from the Real Intent web-site.

About Ascent IIV

Ascent IIV is a state-of-the-art automatic RTL verification tool. It finds bugs using an intelligent hierarchical analysis of design intent. No test bench or assertions are required, making it easy and efficient to find RTL bugs earlier in the design flow before they become more expensive to uncover. The analysis minimizes debug time by identifying the root cause of issues, and provides the VCD traces that show the sequence of events leading to an undesired state. Ascent IIV has the speed and capacity to handle design blocks exceeding 250K gates and provides a wide variety of complex checks including FSM deadlocks, bus issues, and constant bits and nets. If SVA or VHDL assertions written in PSL are available, Ascent IIV can use these as constraints to enhance the analysis.
