Sequential vs Combinational

"Combinational Circuits": Circuits whose outputs only depend on their inputs at the previous Circuit Block#Circuit Tick. Examples include splitters, combiners, and gates, all custom circuits created in-game, etc.

"Sequential Circuits": Circuits which aren't combinational, meaning that their outputs may depend on some kind of internal state and respond to the time-varying behaviors of their inputs. Examples include NBitDLatch(n), Clock(t), RisingEdgeDetector, etc.
