Compiling and Elaborating Your Design

If the csrc working directory is not located on a local disk, set the

incremental compile directory so that it is. Or change to the local disk

(cd local_disk)

and run the compilation there. This ensures that

VCS can quickly access the compilation directory. If the link step takes

more than a few seconds on a small design, then you know that you’re

accessing files over the network.

Managing Temporary Disk Space on UNIX

The temporary disk space partition (/tmp) causes errors if it becomes

full. Two major users of this disk space during a Verilog compile are

VCS and the C compiler. Either of these can cause large amounts of

data to be written to the temporary disk space. Solutions to the

problem are as follows:

• The solution to the C compiler’s use of temporary disk space is

to use the current directory, or other large disk. This is done by

adding the appropriate arguments to the C compiler via the VCS

compile-time argument -CC, as in the following examples for Sun’s

C compiler on SPARC:

vcs -CC "-temp=." a.v

vcs -CC "-temp=/bigdisk" a.v

• You can also set the TMPDIR environment variable to a large disk

location that is different from /tmp.

On Sun SPARC, and most other machines that use a C compiler

other than Sun’s C compiler, the environment variable TMPDIR is

used to specify compiler temporary storage.
