After compilation, never assume success. You must analyze the reports. You must analyze the reports
This has walked you through the complete lifecycle of a synthesis run: from setting up 90nm libraries to generating a final DDC database. The 2021 version of DC is a workhorse—reliable, fast, and incredibly deep.
To move from "tutorial" to "expert," adopt these 2021-specific practices:
# Define the target technology library (the standard cells you are mapping to) set target_library slow.db
