4.所有在过程块中赋值的变量不能在其他任何过程块再次赋值 1.2. system verilog特有的过程块(可综合) 通过always_comb,always_latch,always_ff过程块相对于always可以更明确的反映设计意图 1.2.1. 组合逻辑过程块(always_comb) Eg. always_comb If(!mode) //mode在敏感list中 Y=a+b; //a,b在敏感list中 E...
3.1.非压缩数组(unpacked arrays) l Verilog数组 变量及线网均可以用于数组。 声明:<data_type> <vector_size> <array_name> <array_dimensions> verilog一次只能访问数组的一个元素。 数组中各个元素存储位置相互独立 需指定起始地址及结束地址eg.int array [64:83]; //地址从64-83的Verilog数组 l SV数组 增...
合理的使用宏可以大大简化我们在使用SystemVerilog编写代码的工作量,如果你不熟悉宏的使用,不仅降低写代码的效率,同时在阅读别人写的代码时也会产生诸多困惑,这里的例子将揭开`, `", `\`"这些宏中常用的符号的含义以及如何使用它们的神秘面纱。 我们还将探索UVM源代码中的一些宏,并建立编写宏的风格指南。 在我们开...

expect操作符类似于verilog中的wait。expect用于等待一个成功检测的property,并带有阻塞作用。expect的原语结构非常类似于assert,并允许带有成功与失败情况下的响应块儿。 initial begin @(posedge clk); #2ns cpu_ready=1'b1; expect(@(posedge clk) ##[1:16] memory_ready=='b1) ...
