Innovus place and route

Cadence Innovus PnR Qualification Handbook

Free to read online, PDFs 199 rupees

A stage by stage qualification handbook for Innovus place and route, in 16 chapters from tool and session qualification and design import through floorplan, placement, clock tree, routing, optimisation, extraction and signoff handoff. Each chapter says what to check before you start the stage, what to run, how to read the report, and what counts as healthy, suspicious or a hard stop, so you can decide whether a run is fit to move on instead of only whether the tool finished. It includes a sanity check sheet and a command sheet for every stage, and 486 command forms.

Read every chapter free on the site. The paid download gives you two PDFs for 199 rupees: the 290-page handbook and an 83-page cheat sheet book.

Read free

Legacy commands are checked against the vendor reference. Nothing in the book claims a command was run on a live design. Example output is synthetic and thresholds are illustrative.
