Is it possible to define a preprocessor macro in Xilinx ISE

[Swarna B]

Is it possible to define a macro through the GUI of ISE or by any
command line
means? I mean, just like we give a +define+MACRO_NAME along with a
verilog
compilation commandline in Modelsim or in NC verilog. How do I do it?
As, otherwise, it becomes quite messy affair of commenting and
uncommenting
lines containing `define in the source code. Xilinx Answer records
don't seem to have anything on this.

I wish I knew your answer!

Please explain how you got that +define to work in ModelSim. I get no
effect. That feature is documented in the pdf manual, but it's not in
html manual, and it's not in the list of command-line options when I
type "vsim -help".

You need to add +define to "vlog" command instead of "vsim"

Doh! Thanks, works fine. I'll go stand in the corner for an hour.
