Compiling and Elaborating Your Design
VCS assigns the source file dev.v to the default logical library called
work.
You can specify either absolute paths or relative paths to the source
files.
Overriding the Search Order in the Library Mapping File
You can use the -liblist logical_library+... compile-time
option to alter the search order VCS uses. If the library mapping file
lists the lib1 logical library first, you can tell VCS to search lib2 first
with the following VCS command line:
vcs +v2k dev.v -libmap lib1.map -new_dr /net/design1/
design1_1/indev.v /net/design1/design1_2/indev.v
-liblist lib2+lib1
Specifying Multiple Library Mapping Files
You can enter multiple -libmap options for multiple library mapping
files. If you do the search order will be based on the order of the logical
libraries in these files and the order in which you enter the files on
the vcs command line.
Displaying Library Matching
You can tell VCS to display how it matches source files to logical
libraries with the -libmap_verbose compile-time option. VCS
display messages similar to the following:
Mapping file gatelib/indev.v to logical library ’gatelib’
