RTL verification for semiconductor and RISC-V teams
Know what failed. Know what to do next.
We investigate design bugs, resolve coverage gaps, and build checks your team can trust. You receive the findings, supporting evidence, and files to run the checks again.
Where we help
Start with what is blocking your team.
Choose the problem you need to resolve. Each service explains the work, the inputs we need, and what comes back to your team.

RISC-V verification
Turn an architectural requirement or failure report into checks your team can inspect and rerun.
- 01
Define the rule
Identify the required behaviour and its configuration or software assumptions.
- 02
Exercise the RTL
Use tests or properties to expose a violating sequence.
- 03
Hand over the evidence
Record the result, proposed correction, and remaining limits.
Concept illustration
What you receive
- A test plan tied to the agreed architectural requirement.
- Reproduction scripts, run settings, and evidence for observed failures.
- Checks of the proposed correction and any remaining unknowns.
- A handover stating the tested revision, assumptions, and limits.
A closer look at the work
A halt request lost between states.
Ordinary tests pass on four deliberately changed versions of a real RISC-V controller. Temporal checks expose how a brief halt request can be lost during a stall, exception flush, or debug return.
Real upstream controller. Synthetic faults. Module-level scope and assumptions are recorded.
- 01
Establish the baseline
Run the ordinary checks on the original controller and each seeded variant.
- 02
Test the boundary
Move the request around the transition and check which event the controller services.
- 03
Isolate the failure
Require the intended diagnostic, preserve passing neighbours, and record the exact source and logs.
What comes back to you
An answer your team can work with.
The finding
What happened, what caused it, and which items remain open.
The evidence
The agreed tests, properties, logs, and traces behind the conclusion.
The handover
Run instructions, assumptions, and limits so your team can continue the work.
Working together
Start with a conversation about the problem.
We agree the scope and completion criteria before work begins. Confidential RTL is shared only after an NDA and an agreed exchange process.
- 01
Describe the blocker
A few lines about the design and the issue. No proprietary source code.
- 02
Agree the work
Inputs, deliverables, access, and completion criteria in writing.
- 03
Review the result
Walk through the findings and rerun the agreed checks in your environment.
Bring us the verification problem that is holding up your team.
Share the problem in a few lines. We will discuss the scope before any confidential RTL changes hands.
