When did the XC7K70T get so small?
I'm debating adding a proof-of-concept of my high speed serial capture block to it, although memory depth will be quite limited. The entire chip has only 4.8 Mbits of memory so with two channels and some BRAM used for other stuff, I'll have a max of ~2 Mpts per channel. That's still a fair bit especially since I'll be capturing after the CDR (i.e. I don't need to oversample).
And then I still have to implement CDR trigger functionality at some point.
But before I do any of that, more ngscopeclient driver stuff to do to support the existing feature set. And probably some more gateware work will be needed to support RX sub-rate modes.
