Real Intent Unveils New Release of Ascent Lint for Early Verification of Digital Designs

Enhancements and new features add broader hardware language support, DO-254 compliance testing

SUNNYVALE, Calif. – Feb. 25, 2015

Real Intent, Inc., whose verification solutions accelerate electronic design sign-off, today announced the latest version of its Ascent Lint product with significant new enhancements for users. Real Intent’s Ascent products find design errors leading to improved quality of results and higher productivity for both design and verification engineers.

Ascent Lint already is the industry’s fastest and most accurate tool for early verification of digital designs. The new version for 2015 delivers enhanced support for the SystemVerilog language, DO-254 policy files for compliance testing of complex electronic hardware in airborne systems, deeper rule coverage and easy configurability. Additional notable enhancements and new features for Ascent Lint include:

  • Enhanced VHDL finite state machine (FSM) handling for deeper analysis
  • 17 new VHDL and 12 new Verilog lint rules that ensure design code quality and consistency for a wide range of potential issues
  • Lower noise in reporting of design issues

Ascent Lint is tightly integrated with MathWorks’ HDL Coder™ that automates the setup of files and commands for Ascent Lint. HDL Coder generates portable, synthesizable Verilog© and VHDL code from MATLAB functions, Simulink models, and Stateflow© charts, for users of the MATLAB and Simulink© products. Kiran Kintali, Product Development Lead at The MathWorks, explains the significance: “This tight integration enables users to verify that the RTL code generated using HDL Coder is compliant with users’ coding conventions and industry standards for a safe and reliable implementation flow for digital synthesis tools used by ASIC and FPGA designers. We see that Ascent Lint has excellent performance and accuracy in verification of our extensive library of toolbox functions. We believe the new DO-254 compliance testing will be a welcome addition for the thousands of users of HDL Coder.”

Many RTL engineers have been proponents of RTL linting since its inception to deliver high-quality functional designs on schedule. These engineers lint their designs constantly to uncover common and uncommon code issues to try to avoid spending expensive cycles in the simulation and synthesis stages. The Ascent Lint flow gives designers a setup-free, push-button process that provides interactive results and can be run at any point in the hierarchy – from chip level to complete blocks to leaf modules. Designers have confidence in the tool because the reporting of false failures is very unlikely.

According to Graham Bell, Vice President of Marketing at Real Intent, “Our new Ascent Lint release addresses the needs of companies developing next-generation designs for FPGAs or complex SoCs. It is a direct result of Real Intent experts working with industry leaders to define and implement richer rules. The addition of DO-254 compliance testing helps ensure that designers’ airborne electronics meet the industry standard for quality and reliability. The new enhancements demonstrate Real Intent’s commitment to support design engineering teams with the best possible tools for verification of digital designs.”

For more information about the new enhancements for Ascent Lint, please watch a short (two-and-a-half-minute) video by Srinivas Vaidyanathan, staff technical engineer at Real Intent below. In addition, Real Intent will exhibit the new version of Ascent Lint, along with its other products, at DVCon, CDNLive Silicon Valley, and SNUG Silicon Valley next month.

Availability The new release of Ascent Lint is available in March 2015. Pricing depends on product configuration.
