那个，很不好意思说。assign F=Y_L[0]&Y_L[1]&Y_L[2]&Y_L[3]&Y_L[4]| ~(Y_L[5]&Y_L[6]&Y_L[7]&Y_L[8]&Y_L[9]&Y_L[10]& Y_L[11]&Y_L[12]&Y_L[13]&Y_L[14]&Y_L[15])这句后面没有加“分号”。然后 if 语句后面如果有多句话，注意Begin ... end...
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. ...
Verilog HDL can do pretty much anything - the syntax of the always @(<whatever>) is very flexible. However, when you go to synthesize the design, the code has to map to an available piece of hardware on the FPGA. Verilog HDL几乎可以做任何事情 - always @(<whatever>)的语法非常灵活。 ...
Verilog HDL can do pretty much anything - the syntax of the always @() is very flexible. However, when you go to synthesize the design, the code has to map to an available piece of hardware on the FPGA. On the FPGA we have combinatorial logic (LUTs, MUXes, etc…). These are inferr...
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...

infinite loop. However, when combined with a Verilog event expression, it can be used to model combinational and sequential logic. SystemVerilog adds several new versions of “always”, in addition to Verilog always block, to address some limitations and pitfalls of the original Verilog syntax. ...
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,并在括号()中的@运算...
(e.g., 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 hardwaresimulation...
