Is there a way to detect a signal combination in chipscope

[syedshan]

Hello every one,

as the title suggest, Is there a way to detect a signal combination in chipscope
I know we can do some similar thing with trigger conditions, but I dont want them to use aas triggers, but I have few glitches in my design that I found accidently, hence I want to know if there is any way I can find the combination. The process halts there etc.

Of it there is any other technique that experienced users use then please share with me. I will surel;y appreciate it.

Thanks in advance,

Shan

What process? are you trying to halt the FPGA? you cannot do that unless you design it in such a way.
I dont know why you dont want to use triggers. All chipscope is is a monitor - you need triggers to force a download from the continuous buffer on the FPGA to the PC.

I think you must synthesize extra logic to do that if you don't want to use a trigger condition.

Do as much debugging as possible in a simulator. Create test cases for the logic you want to test.
Chipscope is great for finding the reason for non-working logic, but as soon as you have an explanation or a theory, do the work in a simulator.
It will take much longer time to get all details right if you only work in the lab with chipscope.

Do you use a simulator and a test bench for your design?
