I'm trying to build the following part of a circuit:

enter image description here

I'm wondering what the part is that has "HI" written on it; I couldn't find it in any PSpice guide.

'HI' would probably indicate a high voltage level, or logic-level high, also known as Vcc, usually 1.8 V, 3.3 V or 5 V.

It's up to the designer to determine what value 'HI' is, and it is probably located somewhere else on the schematic.

Also that is a port, it indicates that the two nets are tied together in the schematic, without them being wired together directly (thus making a rats nest of wires).
