Hello,

I am having exactly the same problem reported by aprado, but I am using Signaltap of quartus v10.1sp1 on Windows.

I've never experienced this before... and it is scaring me!

I've got a signal stuck at '1'. If I put the trigger on a change of its value never happens. But if I trigger on some other signal that really moves, then I see the previous signal that changes!!

I am using a USB Blaster cable.

Please let me know if anyone has some hits because it is really frustrating.

Bye
