SignalTap -> Data Depth set to 0 -> when useful? - SignalTap -> Data Depth set to 0 -> when useful? Hi All, In SignalTap there is an option to define the Data Depth to '0'... When is this option useful? Thank you! Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? Not sure what you mean. It seems like this is how it would work based on what Sheng says. Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? The question was to @ ShengN_Intel - he is an insider.... So in my guess he could provide a mature answer Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? I've never used it, but I presume the logic analyzer would still trigger and stop running. You just wouldn't see any data on the Data tab. Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? OK, so a waveform will not be drawing .... So, how to know that the condition has been met? Should I see some message in the Data Tab instead of waves? Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? Hi, When sample depth 0 is selected, no ram is needed. In that case, STP becomes a simple logical condition test tool. The waveform viewer still tells you whether condition is met or not, instead of drawing waveforms. Best Regards, Sheng p/s: If any answer from community or Intel support are helpful, please feel free to mark as solution and give Kudos. Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? As I thought. IMO this option is useless (0 samples = no data). Just another bug in quartus. Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? With Data Depth of 0 it seems nothing is captured.... So the question was when the Data Depth is actually useful (if ever)? Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? Yes, I get it. I'm asking what is the actual picture when you press "run analysis"? Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? Replies: Re: SignalTap -> Data Depth set to 0 -> when useful? Sample depth? Hmm.. Never paid attention. Now I'm curios too ) What exactly signaltap shows when sample depth = 0? I can't check it right now myself.
