I threw together a quick python script to mux the binary files. I think I got it right -- the resulting logic-1-1 file is exactly twice the size of the two source files. I've attached the two source srzip files and the resulting output srzip file. So I'm guessing I made some sort of mistake in the metadata file. I've attached that as a text file as well. I'd be super grateful if you could take a glance at it! Maybe there is a way I can make Pulseview spit out some debugging info or a more detailed error? Thanks, Jason
