Overview

Questa CDC Verification

Questa CDC identifies errors using structural analysis to recognize clock-domains, synchronizers, and low power structures via the Unified Power Format (UPF). It generates assertions for protocol verification along with metastability models for reconvergence verification.

Key Features

Questa CDC High Performance Analysis

Using only your RTL (and UPF power intent file), Questa CDC solutions automatically generate and analyze assertions to rapidly identify chip-killing clock-domain crossing (CDC) issues.

Targeting CDC challenges

Automated Assertion Generation & Analysis

Using only your RTL and UPF power intent file, Questa CDC solutions automatically generate and analyze assertions to rapidly identify chip-killing clock-domain crossing (CDC) issues.

Questa CDC finds errors using structural analysis to detect clock-domains, synchronizers, and low power structures via the UPF. Questa RDC formally verifies reset domain crossings to exhaustively identify reset domain crossing issues in SoC and system designs. Questa Signoff CDC automatically generates and analyzes assertions to rapidly identify chip-killing glitches and other clock domain crossing  issues.

Capacity and efficiency

Industry-Leading Scalability and QoR

When analyzing billion-gate designs, minimizing “noise” is critical. Questa CDC comprehensive, hierarchical, formal-based analysis searches
through DUT elements for high throughput and noise minimization,
simultaneously providing industry-leading scalability and high quality of results,
while enabling CDC IP reuse.

Immediate productivity

Ease of Set-Up and Use

Questa CDC supports the
Synthesis Design Constraints (SDC) format for clock- and
port- domain settings, and it includes a TCL scripting
environment with powerful control and reporting
capabilities. Questa CDC automatically
identifies your clocks and clock distribution strategy,
minimizing set-up time.

Questa CDC Verification Resources

Questa CDC automatically identifies errors related to clock-domain crossings—signals/groups of signals generated in one clock-domain and consumed in another. The technology checks all potential failure modes, and presents the user with familiar schematic and waveform displays.
