Does nextpnr supports multiples names per net ?
<daveshah>
No, it doesn't, even though the JSON provides them
<daveshah>
atm the JSON frontend picks the name with the fewest $s, fewest .s and alphabetically lowest
<daveshah>
in that order of priority
<tnt>
Ok. The issue arose only when seting up clock constraint and a different name was picked.
<tnt>
xobs: ^^ theres is the problem :)
<daveshah>
Yes, that's something of a known issue right now
<xobs>
tnt: woo, I'll just have it generate a timing constraint for each possible net name.

Mmm, I think I'll have to resign myself to have some special hw handling for control transfers. Doing it purely in the softcore I always have some issue somewhere ...

tnt: It looks like one workaround for migen is just to do platform.add_period_constraint() for each signal on that wire, and one of them is going to end up selected by nextpnr.
<tnt>
xobs: ok, at least there is a workaround :)
