    • Preventing Glitch Nightmares on CDC Paths

      As we are investing more in automotive and safety-critical designs, there is a renewed focus on design reliability. Glitches on clock-domain-crossing (CDC) signals will undoubtedly reduce reliability and lead to potential silicon failures. Hence, CDC verification is essential at both the RTL and the gate-level. Previously, we have been focusing on preventing and catching glitches on the data multiplexing paths.

  4. Block Container: Questa Design Solutions Introduction

    1. Questa Design Solutions Overview

      Questa Design Solutions tools are built on a consistent foundation with a common debug and user interface, producing designs that are correct-by-construction, proving designs meet the designer’s intent and the project’s quality requirements, and protecting the design throughout its development.

      The high impact of design issues on projects

      Mistakes happen, but finding and fixing issues late in programs increases overall program scope, as well as schedule and resource requirements. Competitive pressures push teams constantly to do more. Functional verification teams face significant challenges to build testbenches quickly, uncover design issues and enable rapid debug. Incomplete or incorrect bug fixes (or even a hurried introduction of new bugs) compound the problem. In addition, there are classes of design bugs that are challenging to catch at all in functional verification.

      Superior capabilities and quality of results

      Through a combination of data analysis, hierarchical and multi-modal technologies, leading analysis engines providing advanced static verification technologies, Questa Design Solutions provides fast analysis with high quality of results and minimal noise. These analyses provide not only results, but insight behind the issues, such as metrics, visualization and recommendations. Questa Design Solutions delivers these results and insights, without a testbench, with technologies built to scale across the most challenging designs and projects.
