statements in verilog file

[yowahoshi]

Hi guys,

I am new here and I need some help from you.
While looking through the verilog files of some cell libraries, I realise 2 definitions at the top and I wonder what do they mean. They are as follow:

define NTC 1
define RECREM 1
define setuphold 1

My guess is that they are for enabling negative timing check and recovery and removal time checks and setup and hold time checks for SDF back annontation. Is that correct?

Thanks in advance.

Regards,
Yogah

Remember: compiler directives are starting with backquote
so it is correct to write

`define NTC 1
`define RECREM 1
`define setuphold 1


tnx
