design-for-eco skillA
design-for-eco is agent-read markdown (skill) from vibeic/vibe-ic: Design-for-ECO methodology — pre-place a distributed pool of tied-off spare standard cells/gates and reserve spare ECO pads so that a late-stage bug can be fixed with a cheap metal-only ECO instead of a full base-layer respin. Covers WHY (metal-only vs base-layer respin cost), WHAT to insert (inverter/nand2/nor2/dff/mux2/aoi/oai mix, ~1-5% density, tie-offs, even spatial distribution, reserved ECO pads), WHERE in the flow (after placement, before CTS), ECO-aware metal fill, and the HARD preserva.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add vibeic/vibe-ic/design-for-eco@git:20260822.6dd9761mdr add vibeic/vibe-ic/design-for-eco@sha256:a5c1ce9e0238198ePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
