照惯例,还是先将官方说明贴出来,verilog 2001关于blocking and non-blocking assignment 表述如下: blocking assignment :A blocking procedural assignment statement shall be executed before the execution of the statements that follow it in a sequential block (see 9.8.1). A blocking procedural assignment state...
In the always block above, the Blocking Assignment is used. In this example, the value 1 will immediately propagate to r_Test_3. The Blocking assignment immediately takes the value in the right-hand-side and assigns it to the left hand side. Here’s a good rule of thumb for Verilog:...
延迟指定时间后计算和赋值。 赋值延迟的过程赋值,Delayed Assignment Procedural Assignment,如: always @(A) B = #5 A; always @(posedge clk) Q <= @(negedge clk) D; 事件触发时,先计算RHS,延迟指定时间,再赋值改变LHS。 还有一种带repeat循环的Intra-Assignment Delays的过程赋值,例如: always @(IN) O...
即:blocking=a+1,计算和赋值一步完成,blocking=2 非阻塞赋值,即:non_blocking<=a+1 的右式计算。a+1计算结果为2(但还未赋给左式!) $display计算及打印输出,此时结果: blocking为2,non_blocking还保留初始值0 Q2 非阻塞赋值语句,给左式赋值,即:non_blocking=2 Q3 $strobe计算及打印输出,此时:blocking=2...
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 ...
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。

I am a starter in VHDL (I only know Verilog before). I read some tutorial about VHDL. Now I am confused about assignment in VHDL. Does VHDL has blocking and non blocking assignments which are similar in Verilog? In VHDL, there are two assignments "<=" and ":=". But ...
