# @50: o5 # ** Note: $stop : D:/FPGA/Verilog/Introduction/sample1.sv(84) # Time: 60 ps Iteration: 0 Instance: /comb_logic_assign16 说明,o1, o2比较好理解。阻塞赋值和非阻塞赋值的过程也如前文所述,记住$display和各种赋值在同一个时间步的执行过程。 关注的问题是,延时在各种情况下对事件...
$strobe计算及打印输出,此时:blocking=2,non_blocking=2 所以,最终看到的运行输出是: # display@5: a=1, blocking=2, non_blocking=0 # strobe@5: a=1, blocking=2, non_blocking=2 特别申明一下。在Q1里,存在一个竞争:变量blocking的阻塞赋值和$display。由于仿真软件的限制,仿真的结果是按照语句的先后...
An examination of the Verilog "stratified event queue" (see Figure 1) helps to explain how Verilog blocking and nonblocking assignments function. The "stratified event queue" is a fancy name for the different Verilog event queues that are used to schedule simulation events. 仿真器在仿真时将每个t...
写的很清楚,是你在设计电路的时候将阻塞赋值与非阻塞赋值放在一起使用了,这种情况经常出现在always 块中。这说明你是一个初学verilog的beginner。解决办法,仔细看书,搞明白 = 和 <= 号的作用、区别和使用环境。
If there are multiple assignment statements in the always block in verilog then they can be done in two different ways 1. Blocking using = 2. Non Blocking using <= We will first consider an example usage of Blocking and non blocking assignments in initial statements. The initial statements ...
A VHDL variable assignment is working similarly to blocking procedural assignments in Verilog. They also work for synthesis. The main difference is the process local variable scope. "Global variables" exist in VHDL but are rarely supported for synthesis. Don't confuse Verilog blocking...
Always use non-blocking assignments in always_ff blocks. Always use blocking assignments in always_comb blocks. It is possible to do otherwise, but it is bad practice and not recommended. The described way is the only one that makes sense, well for me anyway. Also, all flip-flops will ha...

It isn't dangerous. I'm not a Verilog expert, but I believe that when you are in an 'always' block, the statements ale taken sequentially, not concurrently. In that case, you can have several assignments in the block, and the last valid one wins. Translate 0 Kudos Copy link Reply ...
SystemVerilog interfaces (SVIs) are supported. Modports for specifying whether ports are inputs or outputs are supported. Assignments within expressions are supported. Building the documentation Note that there is no need to build the manual if you just want to read it. Simply visit https://yos...
