1.3.1. Validating Against Design Rules
You can run the Design Assistant following design synthesis or compilation. The Design Assistant performs a post-fit netlist analysis of your design.
The default is to apply all the rules to your project. If there are some rules that are unimportant to your design, you can turn off the rules that you do not want the Design Assistant to use.
