I am new to FPGAs and i’m still trying to figure out things, i am sorry if this is an oversight on my part.
My TinyFPGA BX when running a verilog led test program (simply outputs power through PIN_1) also gives a small amount of power on all the other pins which is enough for the led to partially glow. I can’t find much on here except mention of pullup behavior, which i tried disabling in the .pcf file to no effect on the outputs. What i tried (with each pin name and no in place of yes):
set_io -pullup yes [port] [pin]
Is there something i’m doing wrong? I saw on the one forum post that the chip sets all pins to pullup by default until it’s done booting? But why after it’s done booting are the pins still partially on?
Also is there any documentation for the pcf file?
