Web10 mai 2013 · To check zero cycle hold check : set_multicycle_path -hold 1. The rule is: Hold cycle = (setup argument) -1 - (hold argument) Based on this equation, you need to derive a hold multiplier value to be specified in the set_multicycle_path command. In the above example, to do a "zero" cycle hold check, 0 = (2) -1 - (hold argument) Web由于-hold默认向右移动launch_clk，现在加上-end后即为指定向左移动capture_clk。 set_multicycle_path 1 -setup -from CLK1 -to CLK2 set_multicycle_path 0 -hold -from CLK1 -to CLK2 . set_multicycle_path 3 -setup -end -from CLK1 -to CLK2 set_multicycle_path 2 -hold -end -from CLK1 -to CLK2. set_multicycle_path 1 -setup … home viva jette https://caalmaria.com
