Sanity checks before floorplan in Physical design Sanity checks are an important step for physical design engineers to make sure that the inputs received for physical design are correct and consistent. Any issues in the input may cause problems in the later stages. So it is important to perform the sanity checks in the initial stage that is when the design is loaded in PnR tool and before the start of the floorplan. Here is a list of checks which must be performed before floorplan of design. Figure-1: Sanity checks before floorplan Library Check: In library check, basically, we validate the libraries before starting the physical design by checking the consistency between the physical and logical library. It also checks the quality of both libraries and reports the error if any. The cells used in the design must be present in the logical as well as in the physical library. Innovus commands: check_design -physicalLibrary : This command will check the physical library and report that al
It would be helpful if you add related tool commands. So someone can try realtime.
