T27.AI

Verification service

Not simulated. Measured on a binary FPGA.

Three tiers, and the button above starts the first one. They are separated because they establish different things: the free run is structural and concludes nothing about whether your design is correct, and saying so is the only way the other two mean anything.

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

Structural — automated — Free for a public repository

Turnaround: Minutes. Every file your info.yaml declares is present, and the design elaborates from that list alone.

Conformance against an independent model — From $2 500 per core, first module free

Turnaround: 3–5 working days. A reference model written from your description of what the design should do — never from your RTL, because a model derived from the code agrees with the code including where it is wrong.

On the board — Quoted per design

Turnaround: Days — board time is queued. Place-and-route on a named part, with the resource counters the router emits after routing completed.

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.
