19:24 <cpresser> I have this open PR in kicad-symbols. Its about the ICE40HX4k vs. ICE40HX8k

19:25 <cpresser> the pinout .xls files by lattice are not identical, but every other resource I found looks like they are.

19:26 <sorear> how do the lattice .xls files differ?

19:27 <cpresser> https://github.com/KiCad/kicad-symbols/pull/1985#issuecomment-542916503

19:30 <tnt> They're the same part.

19:39 <cpresser> is there any other resource for the pinout besides those xls files?

19:40 <tnt> not really.

19:41 <tnt> but given the 4k has really 8k LUTs why would they be bonded differently.

19:41 <cpresser> I even checked the official orcad files, but they are missing the 121-pin bga parts.

19:41 <cpresser> agree, it does not make sense that they are different

19:42 <zyp> cpresser, did you check the migration sheet?

19:42 <zyp> http://www.latticesemi.com/view_document?document_id=49424

19:42 <tnt> if you look at http://www.latticesemi.com/en/Products/DevelopmentBoardsAndKits/iCE40HX8KBreakoutBoard the 4k BG121 doesn't even exist ...

19:43 <tnt> arf wrong link http://www.latticesemi.com/en/Products/FPGAandCPLD/iCE40

19:45 <cpresser> zyp: good point. The migration sheet shows that the pins are all identical.

19:46 <cpresser> thanks for the help. I now feel confident merging that PR.

19:47 <zyp> if the 4k col in the migration sheet disagrees with the 4k sheet just like everything else, it seems pretty likely that there's just an omission in the 4k sheet
