Clock tree spec file
WebClock Tree Analysis Prior to running automated CTS tools, ConTree can be used to … WebOur vendor has strict technology node dependant SinkMaxTran & BufMaxTran rules. The early / late clock derating factors used to calculate On Chip Variation are characterized within these input transition boundaries. Break the clock input transition rules and your STA timing margins may not be valid. ( not a warm fuzzy feeling at tapeout ) Shawn.
Clock tree spec file
Did you know?
Webfor my clock tree synthesis, I use the ccopt flow, and I source the following commands: setCTSMode -engine ccopt. create_ccopt_clock_tree_spec -file ccopt.spec. The .spec file should be based on my .sdc. However, in the generated .spec file I can read something like the following: # Clock tree offset inferred from set_clock_latency -source ...

Web虚幻引擎文档所有页面的索引 WebAll the clock tree spec file entries are documented in the EDI User Guide, "Synthesizing Clock Trees" chapter. Here's a summary of those you mentioned above: MaxDelay = maximum phase delay constraint (default 10 ns) MinDelay = minimum phase delay constraint (default 0 ns) MaxSkew = maximum skew between sinks (default 300ps)
