Simulating Your Design 1
You can simulate your design with VCS using several options and
techniques, which allow you to focus on either performance or
debugging. You can also use runtime options to save and restart the
simulation as required.
This chapter covers the following topics:
• Running and Controlling a Simulation
• Save and Restart
• Specifying a Very Long Time Before Stopping Simulation
• Passing Values From the Runtime Command Line
• How VCS Prevents Time 0 Race Conditions
• Improving Performance
• Profiling the Simulation
