Description
Relaunch the simulator to perform analysis and verification of an updated design.
The relaunch_sim command suspends the current simulation, recompiles the current design into a new simulation snapshot, then connects the current simulation to the new snapshot, and restarts the simulation.
In the typical HDL debug cycle you will compile a design into a simulation snapshot and launch a simulation, configuring the Vivado® simulator IDE to display the signals of interest in the waveform viewer, as well as the scopes and objects of interest. During the debug process you may discover issues with your code or test bench, make corrections to your design, recompile and relaunch the simulator.
This command lets you recompile the design, and relaunch the simulator while preserving the current Vivado simulator configuration, such as open waveform and code windows, Scopes and Objects window settings.
relaunch_sim command applies only to simulations running in the Vivado Design Suite IDE, not stand-alone or batch Vivado simulator runs.This command returns a transcript of its process, or returns an error if it fails.
Arguments
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
