How it works
Instantiates one copy of each standard cell from the GF180mcu 7-track library, and multiplexes the project i/o pins so that the functional behaviour of each cell can be verified.
The instantiated cells have a total of 210 output pins, arranged into 27 pages of 8 pins each. Once a certain page is selected, those 8 outputs are mapped to the project output pins.
How to test
Select a page using ui_in[4:0].
Set the cell inputs using ui_in[7:5] and uio_in[2:0].
The cell outputs for the selected page should appear on uo_out.
