Compiling and Elaborating Your Design

% vcs -Mdir=csrc_debug -debug source.v

This command line enables debugging capabilities but also results

in a slower simulating simv executable. VCS writes the generated

files for this simv executable in the directory csrc_debug.

For faster simulation enter the following vcs command line:

% vcs -Mdir=csrc_perf source.v

This command line results in a faster simulating simv executable.

VCS writes the generated files for this simv executable in the

directory csrc_perf.

64-32-Bit Cross-Compilation and Full 64-Bit

Compilation

Compile and simulate using less than 4 GB of RAM on a 32-bit

machine. However, if you are simulating a very large design, you may

need more than 4 GB of RAM. If this is the case, you can access

more memory by using either a 64-32-bit cross-compilation or full

64-bit compilation process.

VCS provides two types of compilation processes that take advantage

of the additional memory capacity of 64-bit machines:

• 64-32-Bit Cross-Compilation — In this process you use the

-comp64 option to compile a design on a 64-bit machine; then

run the resulting simv on either a 32-bit or 64-bit machine.

• Full 64-Bit Compilation — In this process, you use the -full64

option to analyze and compile a design on a 64-bit machine; then

run the resulting simv on a 64-bit machine.
