I am trying to build a prototype Spartan-II board.
- I am using a XC2S50 TQ144 part with all the mode pins tied to VCCINT
- I am using Xilinx webpack 4.2
- The parallel cable is from insight electronics (Model IJC-2)
- I am using a general purpose PCB and a QFP144 adapter from adapters.com to connect the FPGA to the PCB.
Now when I compile a simple test module and try to download the bit file through Xilinx iMPACT tool, it gives an error saying "Configuration failed: done pin did not go high".
What could be the cause and how can I debug it.
