<jeanthom> Hi everyone, I'm having trouble extracting IOSTANDARD infos from a bitstream with pytrellis. I'm having issues getting sensible results... Here's a simplified version of my code: https://gist.github.com/jeanthom/e62e0adb2bf528102279e4944f89e7bd

<gatecat> the mappings in prjtrellis are really only intended to go from io standard to bits and not the other way round
<gatecat> in practice there's a lot of overlap, and one also has to be careful as the settings are split across the PIC and PIO tiles in some cases

<jeanthom> what would be the best way to extract iostandards from a bitstream?
<mwk> in general it's not always possible, if it's anything like xilinx
<mwk> but basically: take every iostandard, encode it to all iostandard-related bitstream fields, check for a match
<mwk> you may get more than one result
