assign a = b; always_comb begin b = 1'b1; c = a; b = 1'b0; end // 先 always_comb 得: c = a, b = 1'b0; 再assign得:a = b = 1'b0; c = a = 1'b0 // 于是 a=1'b0, b=1'b0, c=1'b0, assign a = b; always_comb begin b = 1'b1; c = b; b = 1'...
到目前为止,我一直能够跟上,但每当我遇到这样的问题,就很难靠我自己解决。 我尝试过多种方法,比如在always_comb块之外添加assign,以及上面链接的前一篇文章中的其他建议,但是我遇到了更多错误。任何帮助都是非常感谢的。 up3模块端口是: 代码语言:javascript 代码运行次数:0 复制 Cloud Studio代码运行 moduleup3(inpu...
在过程赋值语句always语句块里赋值,称为过程赋值,always@ 后面的括号里是敏感列表,如下用持续赋值语句描述了一个异或门电路,与它等价的过程赋值语句是()input wire a,b;output wire c;assign c = a^b; A、input wire a,b;output reg c;always@(a,b) assign c = a^b; B、input wire a,b;output wi...

I noticed the latest docs show that a simple @always_comb block can be converted to a Verilog assign statement with a wire type for the output: http://docs.myhdl.org/en/latest/manual/conversion_examples.html#a-small-combinatorial-design The MyHDL and Verilog are reproduced here: from my...
From the programming prospective, the execution ordering of always_comb and always_ff is important, right? We always assign a variable in non-blocking way inside flip flop from a variable which is driven by always_comb? out_pkt_size <= pkt_size; // pkt_sizeisdrive by alw...
