Use cases

Where teams use Fpgawright

From early-stage RTL to final pre-tape-out sign-off — four common integration points for verification teams.

Use case 01

Clock domain crossing hazard detection

Mixed-frequency designs — the most common in modern SoCs — have CDC paths that are invisible to standard timing analysis until late in the verification cycle. Fpgawright's CDC engine traces every async crossing at the RTL level, including multi-bit signals, reconvergence paths, and async reset propagation.

Teams running multi-clock designs use this as a first-pass gate before any simulation. A 10-minute RTL analysis catches the class of violation that would otherwise surface in week 3 of simulation.

Traces all async crossing paths in the design graph

Detects multi-bit signals crossing without synchronizers

Flags reconvergence hazards in multi-clock topologies

Catches async reset propagation into sync domains

Reports with module name, signal name, and crossing point

Use case 02

CI shift-left — catch violations at commit time

Every commit that introduces a new RTL violation gets flagged before it enters the simulation queue. The GitHub Actions and Jenkins plugins run Fpgawright in diff-aware mode — reporting only net-new violations introduced by the change, not the full baseline list.

Teams using this mode report that engineers fix violations in the same day rather than discovering them weeks later when the source commit is buried under 40 others.

Diff-aware mode: only new violations per commit

Inline PR comments on violation-introducing commits

Configurable merge gate: block on error, warn on low-severity

Native support for GitHub Actions, GitLab CI, Jenkins

10-minute installation, no custom build system required

Use case 03

Pre-tape-out respin prevention

The highest-value use of Fpgawright: a final static analysis pass in the last two weeks before tape-out. The full rule engine runs against the final RTL, and the learning model applies historical bug patterns from your team's previous tapeouts to weight the results.

A tape-out respin at 28nm costs roughly $850K in direct costs plus schedule impact. Fpgawright Team pricing is $490/seat/month — the math justifies even a single prevented respin across a multi-year subscription.

Use case 04

FPGA prototyping verification

FPGA prototyping workflows have different timing and resource constraints than final ASIC tape-out. Fpgawright supports FPGA-specific rule sets covering LUT inference, flip-flop packing constraints, and FPGA-specific CDC paths that don't apply to ASIC implementation.

Teams running parallel FPGA prototype and ASIC paths use Fpgawright to verify both — the rule sets are configurable per project, so prototype violations don't pollute the ASIC-targeted analysis list.
