hi
i have designed a board, with spartan-3 FPGA.
I think the FPGA is not configuring after power-up.
the PROG_B is/goes high, but the INIT_B and the DONE are low.
there is no short circuit from these pins to GND or to neighbour pins.
at the first time, when turned on the board, the core VCC was 3.3V, because the soldering company made a mistake. we fixed it.
through the jtag, i can configure the platform flash, verification succeds.
