Hello everyone,

Can anyone help me what these pins are on Papilio One. I am using Xilinx Spartan 6 FPGA board. Can anyone suggest me what pins on Spartan 6 match with the above UCF file of Spartan 3e.

Hello, you need to find the documentation for whatever board you are using and figure out what pins connect to what. We cannot help you much without knowing what the board is or what the schematic for the board is. You should be able to look at the schematic, or a ucf file for the board, and see that FPGA pin P1 connects to a certain pin on a header on the board. Then you will modify your ucf file accordingly.

 

Jack.
