I´m making a emulatorfor an FPGA Spartan6 XC6SLX16-CSG324C (Its a Nexys 3 board). When I tried make something more complex than light an LED, I though the problem was mine. But, I tried make a simple program to know the issue.
This program, a simple botton-led, I use the C4 pin and U16 pin.
The problem is the C4, a button, does the next error.
Alright, some good being, told me to use the solution of:
1- Change the button to other that works (Works fine, but... there only works 3 buttons from 6, and one is the RESET button)
2- Use the "NET "btnl" CLOCK_DEDICATED_ROUTE = FALSE;", this, doesn´t work fine in the board.
I looking for any new solution that might work. I also have the original proyect that don´t have any of this issues, but it´s a bit strange.
The code is the next:
And the .ucf file:
Any help would be apreciated.
