Set_clock_gate_latency
Web21 Aug 2024 · If there is a transition in clock enable signal when the clock signal is low, there is no effect on the gated clock. But if there is a transition in clock enable signal when the clock signal is high, there will be a glitch in the gated clock. To suppress such glitches, latch-and gate based ICG cell is preferred. WebSpecifies the early clock latency-fall: Specifies the falling transition clock latency-late: Specifies the late clock latency-rise: Specifies the rising transition clock latency-source: Specifies the source clock latency Latency delay value Valid destinations (string patterns are matched using Tcl string matching) Description

Web31 May 2024 · This command with scan_enable -minimum_bit removes all the CGCs with low fanout. Merge_clock_gate command analyzes clock gates at each level of hierarchy in the current design and replaces each set of compatible clock gates with a single clock gate. Two clock gates are considered compatible if all their input signals are logically … WebTo manually specify clock uncertainty, use the set_clock_uncertainty command. You can specify the uncertainty separately for setup and hold. You can also specify separate values for rising and falling clock transitions. You can override the value that the derive_clock_uncertainty command automatically applies.
Web2 Jan 2024 · CTS honors the clock latency defined in the library using the max_clock_tree_path / min_clock_tree_path attribute.

Note that set_max_delay (as well as set_clolck_latency) are both affect by the clock skew. With …
Web24 Jun 2005 · set_clock_latency command is used to define the estimated clock insertion delay during synthesis. This is primarily used during the prelayout synthesis and timing analysis. The estimated delay number is an approximation of the delay produced by the clock tree network insertion (done during the layout phase). WebAn sdc output had come having set_clock_latency values equal to WNS ( -1 was given by me) . It indicates clock is made to reach the ck pins of icgs at the earliest time in perCTS stage (this can be confirmed from the reports where other end arrival time is -1), optDesign -preCTS was run and there is no significant improvement.
