Check design rules before synthesis

Design rules catch structural problems before a simulator or vendor tool gives you a much longer report. The rule command checks the active project against the built-in and project-local rules.

Inspect and run

rr rules list
rr rules check

Use rr rules list to see which checks are active. rr rules check evaluates the project and returns a non-zero result when a rule fails.

The IP manifest remains a separate boundary:

rr ip list
rr ip update

Use those commands to inspect and refresh IP declarations; use rr rules check for design-rule evaluation.

Result

Fix the rule violation at its source, then run the same check again. A clean rule result is an input to synthesis, not a substitute for simulation or timing analysis.
