I have all the outputs assigned as … WebAn RTL module or process that isn’t triggered by a clock edge is said to be combinational. The outputs are purely a function of the combination of inputs, thus the name combinational logic. The process shown above describes a two-to-one multiplexer. It’s a combinational process because there is no clock input. egyptian mace head
