Post-layout parasitic extraction + re-simulation for analog blocks — compares pre-layout vs post-layout specs. Use when the user says "post-layout resim", "extract and resimulate", "parasitic check", or at Step A7 of the analog track.
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
# Analog Extraction Resim
After analog layout in Magic, extracts parasitic RC and re-simulates across PVT corners to check for layout-induced performance degradation. Compares pre-layout vs post-layout results and flags regressions.
## When to use
- Step A7 of the analog track
- After `analog-layout` has produced a Magic `.mag` file
- When the user asks "did the layout hurt my bandwidth?"
## Inputs
1. `analog/<block>/layout.mag` — Magic layout file
2. `analog/<block>/corner_results.json` — pre-layout SPICE results (baseline)
3. `analog/<block>/spec.json` — specs for pass/fail comparison
4. PDK (gf180 or sky130)
## Workflow
1. **Extract parasitics** — emit/validate the Magic parasitic-RC TCL with
`programs/magic_extract_spice_emit.py` (do not hand-write the recipe):
```bash
# emit the deterministic .mag -> RC-annotated .subckt extraction TCL
python3 programs/magic_extract_spice_emit.py --block <block> \
--out-spice analog/<block>/<block>_extracted.spice --out extract.tcl
# or validate an existing extraction TCL (FAILs if it omits `extract all`
# or `ext2spice lvs`, AND if it puts them in an order magic will not

How to install
mdr add vibeic/vibe-ic/analog-extraction-resim@sha256:7903a2b18cdc01edThe line at the top of this page pins the label git:20260831.5c8266a, 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.
