How does clock tree latency affect timing

WebClock Tree Synthesis aims to minimize the routing resources used by the clock signal, minimize the area occupied by the clock repeaters while meeting an acceptable clock skew, a reasonable clock latency and clock transition time. Minimum Pulse Width and duty cycle requirements need to be met for all the sequential elements in the design. WebFeb 16, 2024 · If you define a primary clock on a pin in the middle of the design, only part of its latency is used for timing analysis. This can be a problem if this clock communicates with other related clocks in the design, since the skew, and consequently the slack, value between the clocks can be inaccurate.

Areas like: … WebDec 7, 2015 · There are two types of clock latency: network latency and source latency. Network latency is the delay from clock definition point ( create_clock) to clock pin of a flip-flop. Source latency, also called insertion delay, is the delay from clock source to clock definition point. Source latency could represent either on-chip or off-chip latency. licenca eset 2022 facebook https://torontoguesthouse.com
