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.

Automated assertion generation and analysis

Targeting CDC challenges

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.

Industry-leading scalability and QoR

Capacity and efficiency

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.

Ease of set-up and use

Immediate productivity

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.
