So for 10 time units, other assign statements in this initial block are blocked from execution. After 10 time units, p is assigned value of 1'b1. Right after that, it is time for the next blocking assign statement q = #30 1'b0;Again this blocks any statement from execution, this thi...
Usind the non blocking statement a <= a<<1, it is shifted towards left by 1. But before this execution blocks the execution of the next statement a[0] <=a[3]; we want to assign [a3]'s value to a[0]. If we write the blocking statements in place of non blocking as in ...
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...
alfikpl: I'm sorry for chiming in, I'd just like to clarify something. In an always statement with posedge / negedge keyword, you are always describing a flip-flop (this is always_ff in SystemVerilog), since this is the element that is edge sensitive. All other always statements are ...
