Compiling and Elaborating Your Design
Note that these are only experimental values and you may need to
further adjust them to fit your particular situation.
If you still have memory issues, try running the cross-compilation
process with the +memopt option.
Specifying the Compiler, Linker, and -comp64 Option
When running the 64-32-bit cross-compilation process, you can
specify the compiler and linker in either of two ways:
• Using the path environment variable.
• Using VCS compile-time options -cc and -ld.
VCS assumes that the Sun 64-bit linker is located at the following
location:
/usr/ccs/bin/sparcv9/ld
If VCS can’t find this linker, it uses a 32-bit linker.
To run the 64-32 bit cross-compilation process, include the -comp64
option at the command line, as shown in the following example:
% vcs -comp64 Verilog_source_files
