Greetings,
I was wondering if anyone had encountered the following error and had a way
to fix it?

This is only occurring when I use the split stream block in RFNoC. I have
tried the fixes in [1] but unfortunately they have not helped. Also, fix 1,
I can't seem to before b/c I am missing the file
rfnoc_ce_auto_inst_<device>.v as shown from the output when attempting a
"find" command in Ubuntu.
find: ‘rfnoc_ce_auto_inst_e310.v’: No such file or directory
I ran it on both ~/* and /* with no luck.

Jon Lockhart
