using signal tap analyzer in quartus, to monitor signals live on fpga

[@Breno9629]

hey Tsone, first of all, thank you for your video. I would like to ask you a question. How can I check the signal in specific parts? For example, I would like to check it in sample 16, sample 32 and sample 108 for example at the same time. Depending on the value of it, I would make an action. Just to explain the context: I'm trying to create a decoder for a IR remote control using the FPGA. When I click I receive a signal like this one on your video, but I would like to capture the value in some parts, like sample[16], sample[32], sample[108], is it possible? Or there is a easier way to get these specific values?

Hi, thank you for your question, as i understood, based on some conditions you want to decide which sample you want to observe, 16th sample or 32th sample or etc, so you dont count them by hand. If that is so, i dont know how to do it in tap analyzer, instead i recommend introducing a counter in your HDL, which simply counts when your trigger arrives, and you add that counter into signal tap analyzer, to easily find 108th sample and others. Make sure you also output counter value somehow on any outputs so it wont get optimized out(deleted) automatically during compilation.
