VCS Workflow
The process of using VCS to simulate a design consists of the
following tasks:
• Compiling the Simulation Executable
• Running a Simulation
This approach simulates faster and uses less memory than
interpretive simulators. The process of compiling an executable
binary avoids the extra layers and inefficiency of an interpretive
simulation environment.
On Linux, Solaris, and HP platforms, you can use VCS to generate
object code directly without generating C or assembly language files.
Incremental compilation allows you to avoid compiling modules that
have not changed since the last time you compiled them. For more
details on incremental compilation, see “Incremental Compilation” on
page 3-3.
