RE: [ethmac] a question about ifg_timer.v

You somehow download ethernet MAC from Mahmud and Novan page.

Considering me that is obsolete. I started new implementation and used few things from there.

If you need ethernet MAC, take it from cvs or go to http://www.opencores.org/cores/ethmac/ and

find link from there.

Subject: [ethmac] a question about ifg_timer.v

Hi,

   I am trying to implement the Ethernet MAC (from Opencores) on the FPGA. I have a question about the ifg_timer.v that  has been &nbs p;described in transmit module.

  In the brief description,it is said that the IFG has two intervals time, IFG_1 for the first 60 bit times and IFG_2 for the following 36 bit times of IFG. But in the program I find:

 

`define IFG_LENGTH_2 (5'd22)

 

I'm not sure if the length is "5'd22". Why it is "22"?

< DIV>I think it ought to be "5'd24".

Perhaps I'm wrong,but I want to know the reason.

Would you tell me about it?

Thanks.

 

Regards,

YuZhou
