Once the --verbose flag was added to fasm2bels in the PR #1526, a lot of unknown bits is reported. These bits emerge when a design is run through fasm2bels and then through Vivado.

See the parsed log below indicating the test name and a list of unknown bits for it:

Looks like after f4pga/prjxray#1447 and f4pga/prjxray#1448 are merged, there are only two unknown bits left:

{ unknown_bit = "0040001a_21_25", unknown_segment = "0x00400000", unknown_segbit = "26_697" }
{ unknown_bit = "0040001b_22_6", unknown_segment = "0x00400000", unknown_segbit = "27_710" }

Those bits correspond to:

26_121
27_06

Which appear to correspond to something in ILOGIC/ISERDES part of the IOI3 tiles. I'll investigate next week.
