This project seems to have a serdes block which seems to wrap whatever is in the PDK. Didn't look too far down but from a cursory glance it looked like it was built for an internal clock of 50 MHz (clock default to 20 ns) with an oversampling of 8: 400 MHz
If those numbers are at all right it puts it in useful territory. Very much so for a first spin
For a first spin it looks overall pretty useful. The only nitpick I have would be that `operation` on the DSP tile should be from fabric instead of config (hardcoded in bitstream) otherwise I don't see a convenient way of resetting the accumulator(?)
Thanks for the suggestion on the DSP. Maybe I'll add new DSP tiles that are reconfigurable and keep the config based DSP tiles. I designed Aegis's Terra 1 to be a "good enough first gen" so that's why things are the way they are. I didn't want to over commit on the design for a first generation.
