I’m trying to analyze two serial streams that I have captured. I would like to view them side by side, one with a known good command and another with a command that is being questioned. I got good data into the DSO QUAD, and have two separate VCD files. I have them open in GTKWave, but am now having some troubles analyzing them. This could just be learning curve, but I think it’s more than that at this point.
Fist problem I’m having, when I choose hex display, it doesn’t seem to react. Even if it did, I would expect the sample rate is not correct. 2uS is way off from the 9600 I’m working with.
Second problem, I can’t display traces side by side. If I could simply place the two traces side by side I could look at them and see what bits are different. However no dice, I have to switch from tab to tab to see if I can notice a difference.
Any thoughts? Sorry I don’t know how to get an attachment to stick 
I would post the files for folks to review.
I’m using GTKWave 3.3.8 on Win7 64 bit. I’ll try this again when I have access to a Ubuntu 64 bit machine.
