Intent-focused insight

Questa Design Solutions

Questa Design Solutions is an automated and integrated suite of verification tools for designers to improve initial RTL quality. Design Solutions analyzes code at the design stage to detect bugs early, to improve efficiency, enhance development predictability and ease pressure on schedules.

Questa Design Solutions Tools

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.

Questa Lint delivers verification automation for designers. Questa Lint produces intent and quality-focused insight at the design stage. Questa Lint’s metrics and quality scores are captured and trended over time to ensure that design stays clean.
STATIC RTL VERIFICATION
all

Questa Lint

Questa Lint provides adaptive, integrated insight to the designer to ensure that the quality requirements and intent are met. Pre-configured methodologies provide immediate, intuitive feedback on design issues.

STATIC RTL ISSUE HUNTING
all

Questa Inspect

A fully-automatic formal issue hunting app that finds deeply hidden issues due to common RTL coding errors, Inspect makes it possible to eliminate a wide range of issues without a testbench.

Questa Check X

Questa Check X is an automated application that exhaustively roots out ‘X’ issues at the RTL-level without a testbench.

Questa CDC finds errors using structural analysis to detect clock-domains, synchronizers, and low power structures via the UPF. It then generates assertions and metastability models for protocol and reconvergence verification.
CDC VERIFICATION

Questa Clock-Domain Crossing (CDC) Verification

Questa CDC finds errors using structural analysis to detect clock-domains, synchronizers, and low power structures via the UPF. It then generates assertions and metastability models for protocol and reconvergence verification.

Questa RDC finds errors using structural analysis to detect asynchronous reset domains, synchronizers and low power structures via the UPF. It then generates assertions to exhaustively prove that the design is clean.
RDC VERIFICATION
all

Questa Reset-Domain Crossing (RDC) Verification

Questa RDC finds errors using structural analysis to detect asynchronous reset domains, synchronizers and low power structures via the UPF. It then generates assertions to exhaustively prove that the design is clean.

Questa Signoff CDC uses automated, advanced structural analysis algorithms optimized for gate-level analysis, as well as automated leveraging of waiver and CDC path information from Questa CDC RTL analysis for exacting, “low noise” results.
SIGNOFF CDC
all

Questa Signoff CDC

Questa Signoff CDC builds on Questa CDC RTL analysis and automatically generates and analyzes assertions to rapidly identify chip-killing glitches and other clock-domain crossing issues.
