Unable to change and add new instance in Vivado

Jump to solution

I have generated a "ten_gig_eth_pcs_pma" IP from Vivado 16.4. It contains a module "ten_gig_eth_pcs_pma_gt" for which I need to create 2-instances inside "ten_gig_eth_pcs_pma_block" module.

 

Now, I have named the 2-instances as "ten_gig_eth_pcs_pma_gt_i0 and ten_gig_eth_pcs_pma_gt_i1". But Vivado is giving me an error stating that no such instance exists and keeps on showing me the original IP instance as "ten_gig_eth_pcs_pma_gt_i".

 

What to do ?

Hi @gtushar

 

How you are making necessary changes in the IP core source files? Are you changing it on the disk? Please note that directly making modifications outside of Vivado can result in your changes being removed, as the IP core might get reset or regenerated during the flow. It is important that you mark the IP core as being under user management or lock it before making edits.

 

Please follow the steps mentioned in the below link of UG896 page 115:

Hope this helps.

 

Regards

Rohit
