equivalence-check SKILL.md skillA
equivalence-check from vibeic/vibe-ic is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Run Logic Equivalence Checking (LEC) between two representations of a design — RTL vs gate-level netlist, pre-ECO vs post-ECO, or golden vs revised RTL — to prove functional identity. Use when the user says "LEC", "equivalence check", "formal equivalence", "is this netlist equivalent", "post-ECO check".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Equivalence Check (LEC)
> **Doctrine (v0.1.50):** 把修法寫進工具，而非寫進 prompt.
> Programs first; AI is the backstop. Never claim PASS without the tool's verdict.
After every transformation that touches the netlist — synthesis, DFT
insertion, clock gating, ECO — someone has to prove the result is
functionally identical to the golden RTL. This skill drives that check
through MCP-EDA's `eda_lvs` `yosys_equiv` mode.
## Mandatory Deterministic Preflight
```bash
# MCP tool call (handles SAT-engine corner cases since v0.1.12):
eda_lvs({
mode: "yosys_equiv",
layout_netlist: "<post-transformation-netlist>.v",
schematic_netlist: "<golden-netlist>.v",
top_module: "<top>",
pdk: "sky130", // or "gf180" or "custom" with custom_lib
})
```
The tool returns `equiv_cells_total / proven / unproven` plus
`sat_model_unsupported_cells[]` (for custom-PDK Liberty primitives
without built-in SAT models), and writes the result to `reports/lec.json`
(+ optional `reports/lec.rpt`).
**The PASS verdict is NOT decided in this prose — it is enforced by
`programs/lec_equivalence_check.py`.** That deterministic substance gate
independently re-parses the artefacts (alias-resilient across Yosys

How to install
mdr add vibeic/vibe-ic/equivalence-check@sha256:0c88fff4363e17d1The line at the top of this page pins the label git:20260613.86cacb4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
