To create reproducible Innovus checkpoints, build a checkpoint bundle for a given design and tag that includes matched place, post-CTS, and routed DEF, V, and SDC components. This ensures reproducible place, CTS, and route results with a stable pointer for future resumes.

The best way to restart an Innovus flow from a specific stage is to resume from a chosen stage using generated restore templates. These templates re-create earlier steps using the matched DEF, V, and SDC bundles stored in the immutable checkpoint, avoiding a full flow re-run.

Yes, the Innovus stage checkpoint process requires matched DEF, V, and SDC bundles. Checkpoints are applicable to designs across place, CTS, and route stages only when these matched components are bundled together to enable restart-from-stage workflows.

You need a manifest.tsv and sha256.tsv to verify the integrity of your Innovus checkpoint bundle. They ensure the matched DEF, V, and SDC components remain immutable and reproducible, maintaining a stable pointer for future resumes.

Yes, you can maintain a stable pointer to a current golden Innovus checkpoint tag via a symlink. This symlink points to the current golden tag, ensuring the immutable checkpoint bundle is reliably accessible for restart-from-stage workflows.
