CCmulation

How Cmulation works

From upload to AI-explained results in four steps — no installs, no waiting on a lab machine.

  1. Step 1

    Upload your design

    Bring a Verilog (.v) or SPICE file, or a multi-file archive with a named top module or cell. No local toolchain needed.

  2. Step 2

    Run in the cloud

    Cmulation spins up a managed simulator and runs your job. Each successful run uses one Sim-Credit — and you start with free credits.

  3. Step 3

    See results & waveforms

    Watch status live, then review VCD waveforms, logs, and a clear pass/fail the moment the run completes.

  4. Step 4

    Let AI explain it

    Open a run (or paste a log) to get a plain-language explanation — what happened, how your signals behaved, and what to fix.
