WebNov 24, 2013 · You can, in fact, consider the = to be a blocking (time-sequential) operation even within always_comb sequences. However, the distinction between time-sequential and parallel makes absolutely no difference in this case because the always_comb block is defined to repeat until the instruction sequence converges on a stable state -- which is ... WebOct 16, 2024 · An always block implements the following two concepts: it creates a process thread by execution of the procedural code within the block. Once the procedural block completes, it repeats execution of the procedural block indefinitely. That process continues until the end of the simulation. An initial block does only implements the first concept.

WebJul 17, 2013 · There are the same, but the better syntax is to use always_comb in SystemVerilog. It's better for synthesis because it has syntax restrictions for synthesis that will be caught during compilation of any tool, like a simulator. You won't have to wait until you try to synthesize and find out that your always block is not combinatorial. WebSensitivity lists were a common point of confusion. as a result, always@ (*) is common for unclocked always blocks (always_comb for SV). It eliminates the need to micro-manage the sensitivity list in practical designs. You may see code where there is an always@ (a, bunch, of, variables, and, ports). tennis northern interclub
SV ‘always_comb’ safer than Verilog ‘assign’ - Brad Pierce
Webalways @ (*) is certainly more readable, especially when writing to more than one output signal with a common set of conditions. But @* can have time 0 simulation problems.
