Compiler directives in a file list?

OVM
1

Is there a way to get conditional compilation in a file list? For instance, the following doesn’t work

ifdef FOO f1.v else
f2.v
`endif

when fed to ncverilog (or irun) using the -f argument.

Of course, I can use cpp (#ifdef, #else, #endif) to create a file list for ncverilog/irun. Is there a way to do this with ncverilog itself?

Thanks,
Ramana

A quick solution that would work in any simulator is to put filec.v in your file list:

filec.v

`ifdef FOO
  `include "f1.v"
`else
  `include "f2.v"
`endif

What do yo suggest in case i have library cells
e.g.

i have lib.f which have:
-v cell_lib1.v
-v cell_lib2.v

now in each module the .f file includes a reference to this lib.f
e.g.
moduleA.f

moduleA.sv
-f lib.f
+incdir+…

same for moduleB …

and in top level i have top.f
toplevel.sv
-f moduleA.f
-f moduleB.f

now the compiler parse the lib files for every module …
the simple solution was (if ifdef was supported) to add to lib.f something like
ifndef _lib_guard define _lib_guard
-v cell_lib1.v
`endif

what is suggested (beside to build top.f from the basic components) - is there automated flow which can be used?

The use of -v can be replaced with separately compiled libraries and tool specific options.
