Clock tree spec file
WebIt sounds like what you're looking for (since you say that you don't want to load a clock tree spec file) is a list of nets that are considered "clock" from a timing perspective (ie, case "1" above). The easiest way I can recommend to get this list of nets is using dbGet. WebThe Clock Tree Tool (CTT) for Sitara™ ARM®, Automotive, and Digital Signal …
