Commands
sccom
•
-link
sccom’s -link argument performs the final link of all previously compiled SystemC source
code. Required before running simulation. Any dependent .a or .o must be specified before
the .a or .o on which it depends. Two types of dependencies are possible, and where you
place the -link argument is different based on which type of dependency the files have.
If your archive or object is dependent on the .o files created by sccom (i.e. your code
references symbols in the generated SystemC .o files), then you must specify the -link
argument after the list of files, as shown below:
sccom a.o b.o libtemp.a -linkz
Under the covers, the C++ linker’s command and argument order looks like this:
ld a.o b.o libtemp.a <internal list of SC .o files> libsystemc.a
However, if the .o files created by sccom are dependent on the object or archive you
provided, then the -link argument must be placed before the object files or archive:
sccom -link a.o b.o libtemp.a
In this case, the "undercover" command and argument order look like this:
ld <internal list of SC .o files> libsystemc.a a.o b.o libtemp.a
•
-log <logfile>
Specifies the logfile in which to collect output. Optional. Related modelsim.ini variable is
SccomLogfile.
•
-nodbgsym
Disables the generation of symbols for the debugging database in the library, which allows
source annotation.
•
-nodebug
Disables the creation of a debug database for modules defined in those source files.
Optional. Must not be used with any files containing the SC_MODULE_EXPORT() macro.
Using this option can significantly reduce the compile time for a design, which is useful
when running designs in regression mode. Refer to "Custom Debugging of SystemC
Channels and Variables" for more information.
•
-nologo
Disables the startup banner. Optional.
•
-note <msg_number> [,<msg_number>,...]
Changes the severity level of the specified message(s) to "note." Optional. Edit the note
variable in the modelsim.ini file to set a permanent default. Refer to “Changing Message
Severity Level” for more information.
