Webset_false_path -hold -to [all_outputs] set_false_path -hold -from [all_inputs] This tells the tool that all paths coming from the input pins to the input FFs are false paths and that it should ignore hold-time violations. The same also applies to all paths from the output FFs to all output pins.The result is that there are not a bunch of ... WebAs hold check is performed with respect to same clock edge, any deviation in clock edge (jitter) will affect both launch and capture flop in same way. So for hold uncertainty no … WebSets how many clock cycles elapse between the launch and capture edges for setup and hold checks. The default the setup mutlicycle value is 1 (i.e. the capture setup check is performed against the edge one cycle after the launch edge). kwasi koranteng twum
