WebClock Tree Synthesis (CTS) can automatically generate a clock tree specification from multi-mode timing constraints and then synthesize and balance clock trees to that specification. CCOpt (Concurrent clock optimization) tool extends CTS by simultaneously optimizing clock and datapath to achieve better performance, area, and power. WebAug 26, 2024 · Clock Tree Synthesis. Clock – A signal with constant rise and fall with ideally equal width (50% rise and 50% fall of the signal width) helps to control data propagation through the clock elements like Flip …

WebOct 2, 2015 · design flow simple. Simplify a general design flow post-floorplan should be: 1st timing driven placement according to constraints, skew/latency was considered as ‘ideal’ zero, optDesign –preCTS. 2nd CTS, optDesign –postCTS. Clock tree have insertion or propagation delay after CTS. 3rd routing, optDesign –postRoute, optDesign –hold ... WebNote- The latency values in these commands will be inverted relative to the set_ccopt_property specification. Therefore, if you want to pull up a pin, the value of CTS insertion_delay should be positive (0.10ns in our case) and set_clock_latency value at placement stage should be negative (-0.10ns in our case). ... WebJan 2, 2024 · 3. Manually modifying the automatically-generated CCOpt clock tree specification. If the set_clock_latency SDC command on the clock pin is not present, the automatically-generated clock tree specification can be manually modified to specify the insertion delay underneath the clock pin by using the following command: … bootstrap graphs w3schools
