All,
My setup:
Quartus II 9.0
MAX-II
schematic entry
Don't know if this is a Quartus II issue or MAX-II issue.
No matter what I set my pins to I can never detect a LO (GND) (simple circuit schematic)
The only way I can get the ADDR_Equal is when all inputs are HI (or floating will work on all 6 configurations also)
I have tried all 6 ways for setting my inputs.
3.3-V LVTTL
3.3-V LVCMOS
3.3V Schmitt Trigger Input
3.3-V LVTTL with pullups
3.3-V LVCMOS with pullups
3.3V Schmitt Trigger Input with pullups
Anybody have any ideas on what I am doing wrong?
I have done a simple 2-input AND gate and in Never works when the input pins have the pullups.
