FPGA Sampling probe display error

[xl600]

In LabView 2014F1, I discovered a very disturbing bug.  Take a sampling probe window I've been working with in order to ferret out issues with an FPGA sub-vi:

Scrolling left and right using the mouse results in changes to signal alignment! Which one is correct?  It's difficult to know...

Re-running the simulation (DEN based using a CSV file as a vector input) without touching the probe window results in a identically aligned signal set to the original window (But signals still shift vertically which is highly irritating)

This should be considered a critical bug given that the behavior is unpredictable and results in incorrect signal display. The probe window is critical to debugging FPGA code in LV2014 and if it can’t be trusted to display actual data relationships, it is entirely useless. It should never have made it into the production release of LabView FPGA in this condition.

Hi  xl600

We really appreciate the feedback you provided. I would like to check if we can reproduce this behavior from out end just to be sure that we are dealing with a bug. Have you been able to reproduce this behavior in more than one computer?

Thank you!

I only have the one license so no. The pc is a very straight forward windows 7 installation. The sampling probe also suffers from multiple cosmetic issues.

Waveform and names do not retain alignment, especially when zooming
Zooming has a random effect on vertical zoom and centering
The highlighted wave is not bold enough to see clearly
There's no mechanism to save the probe configuration

All of these can't be installation specific so it looks like the probe needs a lot of attention. I'm hoping a fix can be provided soon for labview 2014 so I don't have to use questa for everything. The license costs are astronomical!

I understand your frustration, in order to be able to report this bug, we need to be able to reproduce the error. I have tried zomming in and out and moving the scroll in the Sampling Probe Watch Window in my computer (2014 FPGA Module), but the lines do not lose alignment.

I was wondering if you could post a zip file with a simplified version of your code, that behaves as you describe, and the steps you follow to reproduce the issue in that code, so we can see the same behavior in our side?
