State the term- Use a define function

This is almost exactly the same approach as #define and -D compiler arg that C programs use. In your  Verilog  code,  use  a  'define  to  define  the  variable  condition  and  then  use  Verilog preprocessor directives such as 'ifdef. Use the '+define+' Verilog command line option. For an illustration:

... to run the simulation ..

verilog testbench.v cpu.v +define+USEWCSDF

... in your code ...

'ifdef USEWCSDF

initial $sdf_annotate (testbench.cpu, "cpuwc.sdf");

'endif

+define+ can also be filled in from your Makefile invocation, which in turn, can be finally filled in your UNIX prompt command line.

Defines are a blunt weapon since they are very global and you can only do so much with them asthey are a pre-processor trick. Consider the subsequent approach before resorting to defines.
