WebOct 5, 2015 · The always @* is intended to infer a complete sensitivity list for both RTL simulation and synthesis from the contents of the block, saving a designer from having to manually specify a sensitivity list to code combinational logic. However, it does not infer a complete sensitivity list when the always @* block contains functions. Namely, it will ... 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. peacock sports login

WebThe logic that is generates is purely combinatorial; a mix of and-gates, or-gates, and inverters (Or LUTs). But the signal paths through that combinatorial logic is not always perfect and the "set" signal could have glitches on it. The signal path through a particular group of gates could take longer than another group, causing the set output ...
