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.

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.

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.

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.
