wire), while the left-hand-side of a procedural assignment (in an always block) must be avariabletype (e.g., reg). These types (wire vs. reg) have nothing to do with what hardware is synthesized, and is just syntax left over from Verilog's use as a hardwaresimulationlanguage...
Verilogalwaysblock Always块是Verilog中的过程块之一。 Always块中的语句按顺序执行。 Syntax always @ (event) [statement] always @ (event) begin [multiple statements] end Always块在某些特定事件处执行。该事件由敏感度列表定义。 什么是敏感度列表? 敏感性列表是一个表达式,它定义了何时应该执行always块,并...
Another way to provide a timing control is in the form of a Verilog event expression. The syntax of Verilog event expression is “@(event_expression)“. For the procedural block that contains the Verilog event expression, it causes the simulator to wait until theevent_expressionhas occurred bef...
Verilog:Modules-Alwaysblock2 Temo 余生很长,且行且珍惜。 For hardware synthesis, there are two types of always blocks that are relevant: Combinational: always @(*) Clocked: always @(posedge clk) Clocked always blocks create a blob of combinational logic just like combinational always blocks, ...

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 sensi...
在Verilog中,always block可以用來代表Flip-Flop, CombinationLogic與Latch,本文比較在不寫else下,always block所代表的電路。 Introduction 在C語言裡,省略else只是代表不處理而;已但在Verilog裡,省略else所代表的是不同的電路。 always@(a or b or en) ...
SpinalHDL is the best hardware description language I have ever encountered, despite having written Verilog and VHDL for many years. Recently, while learning SpinalHDL, I encountered an issue: how to ensure that the generated Verilog code has only one always block corresponding to each signal. ...
If this is the first time you have looked at Verilog Code before, you should start with a tutorial geared for beginners.always_block.v:1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 // Create...
In Verilog, a commonly known rule states that in always blocks, only blocking or only nonblocking assignments should be used, not a mix in one block. Could anybody tell whether a similar rule is valid in SystemVerilog for always/always_comb/always_ff blocks? I have se...
