When there are false timing paths (physically or logically non-existent) between two clock groups, use -physical_exclusive or -logical_exclusive

WebVLSI UNIVERSE Intricacies in handling of half cycle timing paths What is a half cycle path? A half cycle timing path is one in which launch and capture happen on different clock edges. A half cycle path can be in terms of both setup and hold. Web(a) set_false_path -from [get_clocks CLKA] -to [get_clocks CLKB]]. I think this is considering about one way direction. (b) set_false_path -from [get_clocks CLKA] -to [get_clocks CLKB]] set_false_path -from [get_clocks CLKB] -to [get_clocks CLKA]] -> CLKA -> CLKB, CLKB -> CLKA (Bi-Direction) set_clock_groups

So, one way correcting hold violations is inserting delay cells in clock tree synthesis. Also, setup violations can we corrected by sizing the cells and declaring multicycle paths if there are two cycles. dungeons and dragons 5e warlockWebStep 13: Group Certain paths: It is always a good idea to group certain paths together to help better optimisation of paths Synopsys by default works on worst paths.
