How to use command line option(compiler directive) inside verilog model

[tsuresh]

Hi,
How can I use the command line option as a switch inside verilog model ?
Ex:
My command line is (say)
ncelab -delay_mode unit
(or)
ncelab -delay_mode zero

How can I use "unit" or "zero" inside verilog model ?
Requirement is:
I want to change some timings depends on this switch.

Regards,
suresh

you need to do
ncelab -define delay_mode=unit
ncelab -define delay_mode=zero

and in your code have
`define delay_mode unit
`define delay_mode zero

in you code you can use :
`ifdef
`elsif
else
endif

you can check also the ncvlog manual
