I'm new to altera fpga , I've bought development board based on EP4CE6E22 cyclon IV and tryed to program it with basic program in quartus environment
module my_and(a,b,c); input a,b; output c; assign c = a & b; endmodule
I've loaded pin assignment from files that came with the board and programmed it with some chinese jtag blaster.
but when i tryed to push one or the other or both (attached to a,b signals)button - the led turned on , and went off when released (like OR GATE)
so i tryed to program it as OR GATE gate and the board started acting like AND GATE
am i doing somthing wrong?
