Motivation

In supercollider/supercollider#4572 we discussed the need for better documentation on when collection functions test on equality vs identity. For instance, SequenceableCollection:indexOf tests on identity, but you wouldn't know it f

Proposed Behaviour

None of the core VPR algorithms should care if the relevant t_physical_tile is an input / output / IO type.

Current Behaviour

Some behavior is still dependent on whether a tile is an input / output / IO type.

Possible Solution

The relevant code shouldn't need to care. Once all callsites of is_input_type/is_output_type/is_io_type are removed, the

During the work on merging #1419 I figured out that the basic BUFGMUX example works differently on Arty Board and Nexys Video.

The example uses three LEDs:

• led[2] - blinks with slow frequency
• led[1] - blinks with high frequency
• led[0] - blinks with the same frequency as led[2] or led[1] depending on sw[0] state.

On the Arty Board, the example works as intended. On Nexys Video, when
