SignalTap Logic Analyzer waveform display - SignalTap Logic Analyzer waveform display Hello, I am using the SignalTap II logic analyzer on Quartus Prime Version : 18.1.1 Build 646 04/11/2019 SJ Standard Edition. I am tracing logic in the Cyclone V SOC. Sometimes whan I run analysis the waveform display presents blue left and right arrows which allow me to locate the next edge in the trace. Sometimes I do not get the arrows. Please le me know what I need to do to activate the arrows. I provide two screen shots, with arrows and without arrows. Thank you Replies: Re: SignalTap Logic Analyzer waveform display I made a new stp file. Prior to running an analysis I punched in numbers starting at 0 for the aliases. I use the signaltap text file to lift the signal names when I record the results of the analysis. When I ran the analysis the arrows magically appeared. I did not even add time bars. I had been reusing the old stp file. I wonder if reusing the stp too many times confuses SignalTap. Should I be using a new stp file each time I want to add signals? Replies: Re: SignalTap Logic Analyzer waveform display So you're saying you see the Value column but no arrows above it? I click where it says "Click to insert a time bar" and the Value column and the arrows appear. Replies: Re: SignalTap Logic Analyzer waveform display Thank you for replying. I learned from this exchange that the export to BMP function does not show the arrows. I provide a screen shot. I was fiddling with the master and reference time bars trying to enable the arrows. Per your reply, I tried selecting a signal but was unable to activate the arrows. Replies: Re: SignalTap Logic Analyzer waveform display I don't see the arrows in either of your screenshots, but normally you have to select a signal to use the arrows since they are used to jump to the next signal edge for a particular signal. I think you also have to have the master time bar (solid vertical black line) and a reference time bar (dashed line) enabled.
