DE0 - P8X32 Pin Mappings

This was driving me nuts lat night trying to match my Propeller pins to the physical pin on the connector to the GPIO pin name so you could look up the FPGA pin name to put the correct pin into the assigment map to match back to your propeller pin. As mentioned before, the person responsible for Figures 3-8 and 3-9 and Table 3-6 in the DE0 nano User Manual should be pelted with connectors after they are asked to leave the company!
Anyway, I put together a spreadsheet to aid us in our fun and games. One stop shopping for FPGA pin, GPIO pin, connector pin and eventually, Propeller pin.
I haven't done the bottom connector yet but it is equally confusing and poorly laid out in the documentation.
I think I got them all right - the PortA stuff seems to match the pin assignment sheet in Quartus from Chip's P8X32 and the others were used in stitching together the first pin layout of PortB on my P8X64
Enjoy...or not!

Wow, thanks for that. I was just starting to contemplate the same problem. And BOOM there you are with the solution.
I hope it helps. I was ready to throw the Nano user manual across the basement last night trying to figure out the pins...I would have really been upset then since the user manual is a PDF on my laptop!
