( ESNUG 280 Item 2 ) ------------------------------------------------ [2/12/98]
Subject: ( ESNUG 279 #4 ) "Clock" Startpoints In Prime/DesignTime
> Premises:
>
> 1/ CLK_A and CLK_B are derived from SAME clock "phi" thru a clock-tree
> network.
> 2/ Between CLK_B and "DFF" there is another clock-tree.
> 3/ The path "CLK_A - NET_A - NET_C" is longer than "CLK_B - NET_C"
> 4/ I dont (want to) know the instance names of "DFF" in Blocks A/B
>
> Problem: Now I want to report_timing, from "CLK_B - NET_C" ?
From: Oren Rubinstein <oren@gigapixel.com>
Try:
report_timing -from all_registers(-clock CLK_B -clock_pins) -thr NET_C
If this doesn't work, you can also try to (temporarily):
set_false_path -from CLK_A -to NET_C
and then
report_timing
