litghost,kgugala: just FYI for ice40 timing I'm pursuing patching the xml after merging since there is currently no sim.v files for v2x (although mithro has a WIP PR with them started).
<mithro>
elms: Why not just edit the XML directly?
<elms>
mithro: Manually enter the values? I'd still like to pull the values out of the SDF using a script
<mithro>
elms: Well, initially it might be better to just do it by hand?
<mithro>
Specially if we end up going v2x on ice40?
<elms>
mithro: Ahh I remember now too that the timing all depends on the final target device too. So hx1k has different timing to lp1k. Next pnr uses three timing models. I think icetime has a model for each
<mithro>
elms: You could add each with a "devce=xxx" attribute and then xsltproc during the merging to filter out the ones which don't match the current device...
<mithro>
elms: Might also be worth just doing only one device first and ignoring the others
<elms>
mithro: what is the short term goal you think I should be focused on?
<mithro>
elms: I think having *some* data getting into vtr and looking at the quality...

kgugala: Question about SDF parser. for multiple triples the are labeled with 'fast' and'slow' for IOPATH, but if I understand the spec I think these are for 0->1 and 1->0 transitions. Does the xc7 sdf have a different meaning?
