Post-CTS and post-route hold violation fixing via buffer/delay cell insertion. CTS always introduces hold violations that must be fixed. Use when: 'hold violation', 'hold fix', 'hold slack', 'fix hold', 'negative hold slack', 'post-CTS hold', 'short path padding', or after CTS completes (Step 19).
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
# Hold Fix — Post-CTS / Post-Route Hold Violation Repair After CTS, clock insertion delay makes fast data paths arrive too early at capture flops, causing hold violations. This is expected and must be fixed by inserting buffers or delay cells on short paths. Hold fixing is iterative: fix -> check -> re-fix until all hold slack >= 0 at the fast (FF) corner. ## When to use - **After CTS (Step 19)**: CTS introduces clock insertion delay that creates hold violations on short paths. This is the primary trigger. - **After routing**: parasitics change path delays, potentially creating new hold violations. - **After ECO**: any timing ECO can shift hold margins. - **Before signoff**: hold must be clean at FF corner for tapeout. ## Inputs 1. Post-CTS or post-route database (DEF + netlist) 2. SDC constraints with clock definitions 3. Liberty files for the fast (FF) corner — hold is worst at FF 4. STA hold report (`report_checks -path_delay min`) 5. Area budget — maximum area overhead for buffer insertion (typically 2-5%) 6. Hold slack margin target (e.g., 0 ps for nominal, +50 ps for guardband) ## Workflow ### Step 1: Analyze Hold Violations …

How to install
mdr add vibeic/vibe-ic/hold-fix@sha256:557cefffa1740352The 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.
