It is just a 4-state data type for a variable that could be interpreted as a hardware register or combinational signal. The thing that makes it confusing for people starting in SystemVerilog and having to go back to Verilog is the single continuous driver …

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 ... WebCAUSE: In an always construct at the specified location in a Verilog Design File(), you indicated that you were describing combinational logic by using the always_comb keyword. However, Integrated Synthesis inferred one or more latches when synthesizing the statements in this construct. tally ho episode 123 https://druidamusic.com

You can enforce pure combinational logic by assigning the default values unconditionally in front of the case statement. I don't see a purpose of using casez. Webcombinational logic. When the inputs of combinational logic change, the outputs exhibit several glitches before they settle to their new values. These glitches can propagate through the combinational logic, leading to incorrect values on the outputs in asynchronous designs. In a synchronous design, glitches on the data inputs of two waits download

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. http://www.cs.utsa.edu/~bylander/cs3793/notes/logic.pdf
