FPGA Pin Function Notes 3 D2 LED Low to Light LED 7 D4 LED Low to Light LED 9 D5 LED Low to Light LED 144 Pushbutton Push to ground, no external pullup. Set internal pullup on FPGA configuration if used. 17 50MHz clock input 73 10uF capacitor to ground 10K resistor to Vcc, for power up reset if needed? 26 Connected to Vcc 1.2V Only needed for EP2C8. The "zero ohm" resistor could be removed and the pin used as normal. 27 Connected to GND Only needed for EP2C8. The "zero ohm" resistor could be removed and the pin used as normal. 80 Connected to GND Only needed for EP2C8. The "zero ohm" resistor could be removed and the pin used as normal. 81 Connected to Vcc 1.2V Only needed for EP2C8. The "zero ohm" resistor could be removed and the pin used as normal.
Onboard LEDs and button
LEDs and button on EP2C5 Board
- D2 is on PIN_3
- D4 is on PIN_7
- D5 is on PIN_9
- key is on PIN_144
Pins 26 and 81 are tied to 1.2V and the default selection is to drive all unused pins to GND, making short circuit and that's why the onboard LM1117 1.2V regulator get really hot. You should go to Assignments->Device->Device and Pin Options...->Unused Pins and set it to "As input tri-stated with weak pull-up" (or "... with bus-hold circuitry"). Then everything stays cool.
