if GTXE2_COMMON should be instantiated?

FPGA: V7

when generate a gig-pcs-pma core, I can find the GTXE2_COMMON is used in code.

 

But from pg047 page141, there isn't GTXE2_COMMON for v7 FPGA (only A7 use it)?

 

So if I can delete it manuaaly?

 

Thanks

Re: if GTXE2_COMMON should be instantiated?

Hi,

 

What is the exact part you are using?

 

Virtex-7 devices have GTX resources. Check this http://www.xilinx.com/publications/prod_mktg/Virtex7-Product-Table.pdf 

 

Thanks,

Deepika.

Hi

 

You cannot remove the GTXE2_Common in the user code.

 

It is required for passing the correct BIAS_CFG value.

 

If you are using multiple SGMII cores in the same quad then a single GTXE2_common is enough.

 

Have a look at the below AR>
