Hi,
I'm using a Virtex-5 FPGA which receives data from an LM97600 ADC from TI and the FPGA uses GTX Transceivers to capture the data from the ADC. In the Evaluation board provided by TI, we were able to observe the stored waveforms using a software provided by TI. However, we have a custom board using the same ADC and FPGA but we no longer have the same frontend system to observe the data.
I know its possible to look at the data itself using Chipscope, but I was wondering if it was possible to observe the data in the form of a waveform using ChipScope.

I assume you mean analog waveforms. ChipScope can clearly show 1's and 0's as a digital "waveform" or values printed on top of a bus "waveform" however it doesn't have the ability to graph the value as an analog waveform. On the other hand you could download the data into a PC, and with a little massaging in Excel or a similar program create a graph.

Ah, ok. I did mean it as an analog waveform similar to what an oscilloscope does. So we wouldn't be able to create a bus of the signal and then kind of plot it over time or clock instances on Chipscope itself ?

I stand corrected. Apparently I never noticed this feature...

Hi,
The analog waveform option is also available in Vivado as well.Refer to the section "Viewing Analog Waveforms" in UG908.
