project_open top create_timing_netlist create_clock -period 10.000 -name clkA [get_ports sysclk[0]] create_clock -period 10.000 -name clkB [get_ports sysclk[1]] # Set clkA and clkB to be mutually exclusive clocks. set_clock_groups -exclusive -group {clkA} -group {clkB} set_clock_groups -exclusive -group {clkC} -group {clkD} # Remove clock groups A, B, C, and D.
