hello folks,
I am trying to connect spartan 3AN FPGA (XC3S50AN) with DSP SOC (TMS320tci6614). I am mapping the I/O's between DSP and FPGA.
The problem is : I need aro und 100 I/O for connecting between DSP and FPGA. But in spartan 3AN there are only 108 max user I/O's.
I am not getting the idea on how to use the I/O for my general purpose. Some I/O's are mentioned as the DUAL type and some for Clocks.
There are 40 DUAL type I/o's and 30 pins are associated with the clock.
Please let me know how can I use these I/O's for my general purpose as it s mentioned in the document that those I/O's can be used by user.
I have enclosed the image containing pin info.
Thank you.
