changing RXPOLARITY attribute in sgmii ethernet k7 core

Hi,

  1. in one of our custom kintex-7 board, we have SGMII interface to FPGA.
  2. we are using edk(14.6 version) sgmii ethernet core"axi_ethernet" of version 3.01.a.
  3. in the board mistakenly,RXP and RXN connections got swapped while connecting to tile pins
  4. so,we wanted to change RXPOLARITY in the core it self,as it is not possible to change on HW
  5. we tried to change "axi_ethernet_pcs_pma_wrap_v3_01_a" module,its in encrypted form
  6. please suggest way to change the parameter

thanks

Re: changing RXPOLARITY attribute in sgmii ethernet k7 core

I believe GT wrapper would not have been encrypted. Can you check this file and manually update the RXPOLARITY input to GT?

Re: changing RXPOLARITY attribute in sgmii ethernet k7 core

Hi,

 

thanks for the reply

 

the module path in which i need to change the parameter is as follows:

 

GTX tile hierarchy path is "ETHERNET/SOFT_PCS_PMA.I_PCSPMA/GEN_K7_PCS_PMA.GEN_K7_SGMII.I_GIG_ETH_PCS_PMA_CORE/transceiver_inst/gtwizard_sgmii_k7_inst/gt0_gtwizard_sgmii_v7_i/gtxe2_i"

 

i am not able to open soft_pcs_pma core it self.

i am checking the following path in installed directory for changing core

C:\Xilinx\14.6\ISE_DS\EDK\hw\XilinxProcessorIPLib\pcores\axi_ethernet_pcs_pma_wrap_v3_01_a

 

thanks
