SigmaStudio 3.5.7 Beta Graphs
FIrst and foremost, THESE ARE GREAT! Previously I was using version 3.4 of SigmaStudio so I am not sure when Graphs arrived. They are just the tools that was missing and I have started to use them extensively.
A few issues I have notice in the beta release wrt Graphs.
1 - They do not always run continuously. I have not discovered why some do and other do not. If and when I do, I will post as a reply.
2 - I can get a behavioral difference by opening and setting the Graphs before doing a compile and download. Versus opening once compiled and downloaded then setting.
3 - The Graphs can easily hang. I get button sticks where the range runs off and results in a big red X across the Graph dialog with another dialog to quit, continue and one other option I can not recall.
4 - Item 3 can be accomplished by simply setting the upper and lower vertical axis setting to the same value.
Again, thanks for this additional great tool.

Hi AzEd,
I apologize for the late response - I have been out of the office frequently over the past several weeks.
Which cell are you referring to? Are you referring to the "Real Time Display" function?
That feature is still in "beta" mode, so there are a few issues that we still need to address.
Brett,
Yes, the real time display. These are just FYI and maybe have already been fixed or noted...
Just to restate THESE ARE GREAT...
Good! I'm glad you like them.
By the way, if you simply want to monitor some near-DC level in the signal flow, you can use a "secret" feature of the DSP Readback cell. If you right-click on it, you can choose an option called "Start continuous readback", and then the cell will update itself at a selectable rate. This works similar to the real time display, but it shows you a number instead of a graph. Give it a try!
Cool! Thanks, will give it a try...
I've also had trouble with the real-time display graphs "hanging" and found that the speed of the PC on which SigmaStudio runs makes a huge difference. The graphs are nearly unusable on a three-year old PC, but work fine with a newer machine that features an Intel Core i3 processor and 6Gb RAM. The graphs are super handy; they make troubleshooting new ideas much easier.
One other solution -- connect an unused DAC input to your flow where you want to observe, viewing it with a physical oscilloscope. To that end, have your PCB layout include a test point on unused DAC(s) for that purpose. Do remember, though, that DACs invert, and the DAC output may need filtering.

This has been resolved in the new 3.7 revision.
