Defining clock signals
Select Edit > Clock to define clock signals by Name, Period, Duty Cycle, Offset, and whether the first rising edge is rising or falling. You can also specify a simulation period after which the clock definition should be cancelled.
![]()
For clock signals starting on the rising edge, the definition for Period, Offset, and Duty Cycle is as follows:
![]()
If the signal type is std_logic, std_ulogic, bit, verilog wire, verilog net, or any other logic type where 1 and 0 are valid, then 1 is the default High Value and 0 is the default Low Value. For other signal types, you will need to specify a High Value and a Low Value for the clock.
