Hi Everyone,
Last time, our Five-Minute Tutorial focused on the new Innovus Placement Optimization. The next step in the flow would be inserting clock trees. Now that we can take advantage of the CCOpt engine to create clock trees, we can also concurrently optimize for timing. But you still have the choice of whether or not to do so. This is a decision that could be design-dependent, and you may want to try both methods and compare the results. In either case, once clock trees have been created, you may need to do some investigation and/or debugging depending on the results. The Clock Tree Debugger comes in very handy here. This Training Bytes video gives a quick overview of the Clock Tree Synthesis flow as well as the use of the Clock Tree Debugger. Never having used the debugger before, I really learned a lot from this one. (As always, you'll need an active support.cadence.com account to view.)
