Simons version

[mnemocron]

Ciao Alexandre,

I just wanted to say hello and thank you for your work.
I used your repo as an inspiration to get my simulation started.
However, I started from scratch and did not use your code, so don't actually merge my request ;)

And I saw that you had an issue with the passthrough version without registers.
I have both features working, maybe my stuff is helpful in any way (perhaps the schematic pictures).
