Unified Command-Line Interface
-k keyFilename
Records interactive commands used during a simulation to the
file named KeyFilename, which can be used as the interactive
command file in subsequent simulations.
Using UCLI
You can invoke UCLI as follows:
1. Compile a design with vcs using the -debug option.
2. Start the simulation with simv using the -ucli option.
To compile and simulate a design so that it results in an interactive
simulation using UCLI, do the following:
Compilation
% vcs [vcs_options] -debug file1.v [file2.v] [file3.v]
Simulation
% simv [simv_options] -ucli
