Overview

Questa Signoff CDC

Questa Signoff CDC automatically identifies the clock and clock distribution strategy, minimizing set up time. Simply read in your gate-level design as well as the RTL-level results from Questa CDC, and Questa Signoff CDC will pinpoint all potential gate-level CDC issues – no testbench is required.

Key feaures

Questa Signoff CDC analysis

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.

Exacting results

Low noise, high accuracy

Fewest false alarms in the industry, so you don’t waste time chasing non-issues, and instead can quickly root cause and resolve actual design flaws. Tight integration with the Questa CDC RTL verification app, reusing all the CDC path and waiver information created at the RTL level to expedite the gate-level analysis and significantly reduce “noise” from false negatives.

SoC-level scalability

High performance

Questa Signoff CDC high performance analysis can process over 100-million-gate designs, and its hierarchical capabilities enable unlimited capacity.

Ease of use

Immediate productivity

Automatically infers clock grouping, re-groups logic belonging to CDC synchronization structures, and re-groups any “bit blasted” busses to prevent redundant violation reports. Supports advanced hierarchical methods to maximize turn-around time. Direct re-use of Questa CDC RTL-level setup information, constraints, waivers and results. Automated SDC import and debug and Liberty models are also supported.
