remove all mention of iostandard and pullup
...
I/O standard is not settable. It is fixed by VCCIO*.
Pull up should be configured by PULLUP parameter of SB_IO.
You can observe specifying PULLUP in I/O does nothing according to the generated bitstream. It is already set by default.
See this: https://prjicestorm.readthedocs.io/en/latest/_static/bitdocs-8k/tile_33_2.html
