   An always block is one of the procedural blocks in Verilog. Statements inside an always block are executed sequentially. Syntax. always @ (event) [statement] . always @ (event) begin. [multiple statements] end. The always block is executed at some particular event. The event is defined by a sensitivity list. What is the sensitivity list ?

   3 Answers. Sorted by: 28. The (*) means "build the sensitivity list for me". For example, if you had a statement a = b + c; then you'd want a to change every time either b or c changes. In other words, a is "sensitive" to b & c. So to set this up: always @( b or c ) begin. a = b + c; end.

   Jul 16, 2020 · The always block is one of the most commonly used procedural blocks in verilog. Whenever one of the signals in the sensitivity list changes state, all of the statements in the always block execute in sequence. The verilog code below shows the general syntax for the always block.

   Mar 13, 2024 · What is an always block? In Verilog, an "always" block is a fundamental construct used to describe sequential logic behavior within digital designs. It plays a pivotal role in defining how a circuit responds to changes in its inputs and the progression of time.

   What is sensitivity list in Verilog?

   • What is sensitivity list? In Verilog, a sensitivity list is a crucial component of an "always" block or an "initial" block. It defines the list of signals or events to which the block is sensitive. The sensitivity list determines when the block will execute its code based on changes or events related to the specified signals.

   What is the difference between a continuous assignment statement and Verilog?

   • In contrast, verilog continuous assignment statements execute concurrently (i.e. in parallel) in our designs. This matches the nature of the underlying circuits, which consist of a number of separate logic gates. The always block is one of the most commonly used procedural blocks in verilog.
