Symbiflow 1.1.0 release was updated to use device package pin names for Pin placement constraints (.pcf) nstead of using internal names (e.g. FBIO_*/SFBIIO_*).
Since IO Mux setting generation script relied on internal names, it didn’t generate the IO mux settings for IOs used inside FPGA correctly.

This issue has been fixed in Symbiflow 1.2.0 release via following commit.
Now Symbiflow 1.2.0 allows using either package pin names OR internal names e.g (IO_*) for placement constrains and IO Mux settings generation handles
both naming conventions. ... e540b71b08
