Physical Verification or other downstream analysis flow of P&R design data which only includes routing layers can miss issues caused by
the current device level IP which is only represented by LEF abstracts. However, replacing the LEF IP abstracts with the current GDS version
provided by layout teams can easily be merged with the DEF routing information and output to disk or in memory during Calibre Physical
verification. This video steps through an example showing how to run this Calibre utility to merge the GDS data with DEF.
- Review inputs for reading LEF/DEF
- Convert LEF/DEF routing data to GDS on disk
- Replace LEF abstracts with GDS IP during DEF conversion
