Propagated_clock
WebThe purpose of building a clock tree is enable the clock input to reach every element and to ensure a zero clock skew. H-tree is a common methodology followed in CTS. Before attempting a CTS run in TritonCTS tool, if the slack was attempted to be reduced in previous run, the netlist may have gotten modified by cell replacement techniques.

WebThe propagated clocks model of timing is the definitive criteria for correct chip function, and is the one used by timing signoff tools in design flows. An ideal clocks model of timing simplifies the propagated clocks model by assuming that the launch and capture clock paths have the same delay (i.e., that L=C.) In this case the setup and hold ...
WebMar 29, 2024 · To include the propagated clock latency (due to CTS) in the IO port delays, you should also use the -reference_pin option with the set_input_delay and set_output_delay commands. This ties the network latency used for the IO to the propagated latency of some flop's clock pin in the core. WebFor propagated clocks, NanoTime calculates the cumulative delays along the clock network, including wire delay. The opposite is an ideal clock. For ideal clocks, NanoTime uses the latency values set on clocks, ports, or pins using the set_clock_latency command, or zero latency if none has been set.
