set_simulation_clock
Usage
set_simulation_clock -clock <clock_name> [-duty_cycle <duty_cycle>] [-offset <offset>]
-period <period in ns>
Options
-clock <clock_name>: Name of the clock signal
-duty_cycle <duty_cycle>: Duty cycle of the clock signal
-offset <offset>: Offset of the clock signal
-period <period in ns>: Period of the clock signal in nanoseconds
Description
Creates a continuous clock signal in the Simulator.
The default value for the duty cycle of the clock signal is 50 and for the offset is zero nanoseconds.
Example
project_open lelut
initialize_simulation -ignore_vector_file on -end_time 100ns
# Group "inDataa inDatab inDatac inDatad" under the name "input_bus"
group_simulation_signal -name input_bus {inDataa inDatab inDatac inDatad}
# Create continuous clock signal named "clk0" with duty_cycle = 50
# and offset = 25ns
set_simulation_clock -clock clk0 -period 10ns -duty_cycle 50 -offset 25
# Set value "1011" for the group of signals
force_simulation_value -node input_bus 1011
# Set value 0 for node "clk1"
force_simulation_value -node clk1 0
run_simulation -time 20ns
# Set value 1 for node "clk1"
force_simulation_value -node clk1 1
