SignalTap: Advanced Trigger Problem - SignalTap: Advanced Trigger Problem I can't get one of my triggers to work in SignalTap. The HCOUNT equality comparison works fine but the VCOUNT equality comparison will not match a bus value of 8! VCOUNT is defined as shown below: bit [ 15 : 0 ] hcount = 0; bit [ 15 : 0 ] vcount = 0; When I click on "Run Analysis", it always stops when VCOUNT=0100h What is the problem? Is this a SignalTap bug?

Replies: Re: SignalTap: Advanced Trigger Problem Glad you have solved the issue. Let me know if there is any other concern. Replies: Re: SignalTap: Advanced Trigger Problem Weird. It's like the bits of VCOUNT got connected to Signal Tap incorrectly (bits swapped). Glad you figured it out. Replies: Re: SignalTap: Advanced Trigger Problem I spent ages fiddling around yesterday - removing logic from the advanced trigger and it wouldn't work. I tried changing both radix on the input object, radix on the bus display (although I doubt that was relate at all). I even tried signed/unsigned and greater than/less than comparisons but nothing would work. It wasn't until I removed VCOUNT from the Node List and added it back that it began to work. Replies: Re: SignalTap: Advanced Trigger Problem I doubt this is the issue (because that would be a weird bug), but have you tried using the same radix for the comparisons, instead of using decimal for HCOUNT and hex for VCOUNT? You should be able to change that without having to recompile (the white boxes in the editor). Also try taking FRAME out of the picture temporarily to see if just the HCOUNT and VCOUNT comparisons work correctly on their own.
