T27.AI

Verification service

Not simulated. Measured on live silicon.

Send your RTL. It runs on a real Xilinx Artix-7 and comes back with a signed report: bit-exact conformance against an independent model, achieved timing, resource usage, and the bitstream — on a fully open-source toolchain, so every number can be reproduced.

What the report contains

Bit-exact conformance

Every node of your datapath checked against an independent reference model with known-answer vectors. Divergence between specification and RTL surfaces before synthesis, not after tape-out.

Timing and resources

Achieved frequency, slack, LUT/FF/BRAM/DSP usage and a latch-free check — measured on a live Artix-7, not estimated from a report.

Reproducible artefacts

Bitstream, test vectors, logs and the exact toolchain versions, so anyone can re-run the whole flow themselves.

No vendor lock-in

Yosys, nextpnr-xilinx, prjxray, openFPGALoader, iverilog. Nothing in the report depends on a proprietary licence you would need to buy.

How it works

1. You send RTL or a specification

And say what “correct” means for it.

2. I build an independent model

Written from the operation, never from your RTL — a testbench derived from the same assumptions as a design agrees with the design's bugs.

3. You get a signed report

Measured numbers, vectors, bitstream, and every command needed to reproduce it.

Pricing

Single core — $300

One module or IP core: bit-exact check, timing, resources, report.

Block — $800

A full block with multiple cores, integration checks and a written analysis.

Tape-out ready — $2 000

Everything above plus the preparation a shuttle submission needs.

Retainer — $1–3k / month

Ongoing verification as your design changes.

What this is not

One device family

Measurements come from a Xilinx Artix-7. This is not multi-corner characterisation and does not claim to be.

Not a sign-off flow

It is an independent check, not a substitute for a full commercial sign-off.

No encrypted netlists

I verify what I can read. Encrypted IP cannot be checked this way.

Estimates are labelled

Anything estimated rather than measured says so, here and in every report.

Have a design to verify? The first module is free, so you can judge the report before paying for anything.
