VCS Environment Variables
Optional Environment Variables
VCS also includes the following environment variables that you can
set in certain circumstances.
DISPLAY_VCS_HOME
Enables the display, at compile time, of the path to the directory
specified in the VCS_HOME environment variable. Specify a
value other than 0 to enable the display. For example:
setenv DISPLAY_VCS_HOME 1
SYSTEMC
Specifies the location of the SystemC simulator used with the VCS
/ SystemC cosimulation interface. See Chapter 19, "Using the
VCS / SystemC Cosimulation Interface".
TMPDIR
Specifies the directory used by VCS and the C compiler to store
temporary files during compilation.
VCS_CC
Indicates the C compiler to be used. To use the gcc compiler
specify:
setenv VCS_CC gcc
VCS_COM
Specifies the path to the VCS compiler executable named vcs1,
not the compile script. If you receive a patch for VCS you might
need to set this environment variable to specify the patch. This
variable is for solving problems that require patches from VCS
and should not be set by default.
