release_simulation_value
Usage
release_simulation_value -node <hpath>
Options
-node <hpath>: Hierarchical path name of the signal or group of signals
Description
Releases the forced value of the specified signal or group of signals. After the signal's value is released, the
Simulator can overwrite the current value when simulating at a future time.
Example
project_open gates
initialize_simulation
run_simulation -time 10ns
puts "Value of out_a = [get_simulation_value -node out_a]"
# Value of out_a = X
force_simulation_value -node out_a 0
puts "Value of out_a = [get_simulation_value -node out_a]"
# Value of out_a = 0
run_simulation -time 10ns
puts "Value of out_a = [get_simulation_value -node out_a]"
# out_a has been forced to 0, it won't be updated during the last 10ns
# simulation.
# Value of out_a = 0
# Release the value 0 hold by out_a
release_simulation_value -node out_a
run_simulation
puts "Value of out_a = [get_simulation_value -node out_a]"
# Previous forced value has been release, out_a is updated with the
# latest value
# Value of out_a = 1
project_close
