Hi,
I have designed a motor controller with the Virtex 4 FX-12 Mini-Module and I of course would like the PWM output pins to never go high during startup or programming. They do go high during this time like I don't have control over this. Do I need external circuitry to prevent this? I have already fabricated a board and it would be nice if this could be handled without doing something like that. I am using ISE/ EDK 8.2. In my system.ucf file I specify the pins to be outputs. Run away motors are not acceptable at startup or during programming. Thanks for any help.
