Problem in replacing 'define macro <text> to vlog +define+macro=<text> in Questasim

Hi

My code has the following ifdef
`ifdef SIMFILE
`include `SIMFILE
`endif

While compiling I give
vlog +define+SIMFILE="file1.sim" -f file_list.f
When I give this way file1.sim is actually not included.

Whereas it gets included only when I explicitly define as:
`define SIMFILE "test1.sim"

I learnt from questa manual and understood that +define+SIMFILE="file1.sim" along vlog is equivalent to `define SIMFILE "file1.sim"
But when I give the +define method mentioned above, the quotes are not actually taken. It either doesnt include the specified file or displays error like "missing quotes"

I find the problem with the quotes.I need to do +define+ along with vlog instead of `define
Kindly help me with this.

Thanks

I found the solution.
It should be
vlog +define+SIMFILE=\"file1.sim\"

Hope this might help someone

You have to be very careful with scripts as different shells will strip the the quotes away before passing them to vlog.

You can use a SystemVerilog technique to add the quotes inside your source so you can use

vlog +define+SIMFILE=file1.sim

In your source, you can do

`define QUOTE (str) `"str`"

f = $fopen(`QUOTE(`SIMFILE));
