pullups for inputs on CAT-Board require 2 signals per input with pullup?

Hi Chris,
As you recall I asked you, if the file ice40_primitives.py from Dave's CAT-Board/tests

https://github.com/xesscorp/CAT-Board.git 

needed to added to the rhea package.

I am doing some testing and created a file

jpeg-2000-test/pc_fast_blinker_jpeg/test_top_cat.py which 

https://github.com/develone/jpeg-2000-test.git

is imported by ex_catboard_jpeg.py with the chgs below.
 
diff ex_catboard_jpeg.py pc_fast_blinker_jpeg/ex_catboard_jpeg.py
26c26
< from test_top_cat import dwt_top
---
> from test_top import dwt_top
48c48
<     brd.add_port('reset_i', 'T2')
---
>     brd.add_port('reset', 'T2')

Running the test_top_cat.py --test and looking at the reset & reset_i signals.
The signal reset is always hi.
The signal reset_i goes lo when driven by the simulation.
 
For XulA2-LX9 I used the pullup=True see the file 
jpeg-2000-test/pc_fast_blinker_jpeg/ex_jpeg_xula2.py from the repository

https://github.com/develone/jpeg-2000-test.git/
This creates the xula2.ucf
