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
在Verilog中,always block可以用來代表Flip-Flop, Combination Logic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) if (en) c = a & b; 在combination logic中省略else,...

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...

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...
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. ...

See the HDL Compiler for Verilog Reference Manual and the VHDL Compiler Reference Manual for ways to infer flip-flops and latches from always blocks with an if statement. DESCRIPTION中的内容和前面的log区别不大,但是它强调了一点,在这个always block内的第一条语句(top level)必须是一条if语句。上面...
