Plan analog layout with matching, common-centroid, interdigitation, dummy devices, guard rings, and shielding. Use when the user says "analog layout", "matching layout", "common centroid", "dummies", "guard ring", "interdigitated", "current mirror layout", "differential pair layout".
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 Layout `analog-sizing` picks W/L; this skill translates the sized schematic into a layout plan that actually survives process variation. Matching and noise immunity live or die on layout, not schematic. ## When to use - Current mirrors, differential pairs, bandgap references, DAC ladders - Any circuit where σ(Vth) or σ(β) matching drives the spec - Circuits near digital noise sources (guard rings / shielding needed) - Before handing off to a layout engineer or Magic / Virtuoso ## Inputs 1. Sized schematic with device list (W, L, M, NF) 2. Matching pairs / groups (which devices must match) 3. Sensitivity list (which mismatches kill which spec) 4. PDK rules (well spacing, latch-up, antenna) 5. Floorplan block size budget ## Workflow 1. **Identify matching groups** — pairs, quads, ratios 2. **Choose matching style**: - Common-centroid 2×2, 4×4 for differential pairs - Interdigitation ABAB or ABBA for current mirrors - Centroid-preserving patterns for large ratios 3. **Dummy devices**: at least 2 dummies on each side of a matching row 4. **Guard rings**: n-well ring around PMOS, p-substrate ring around NMOS near digital 5. **Routing rules**: …

How to install
mdr add vibeic/vibe-ic/analog-layout@sha256:7ce16c06ec5abc23The line at the top of this page pins the label git:20260831.7443919, 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.
