SystemVerilog添加了一个方便的快捷方式,用相同值填充向量的所有位。简单的语法是'0, '1, 'z或'x。这允许填充任何大小的矢量,而无需明确指定矢量大小。 bit [63:0] data; data ='1;//set all bits of data to 1 3.抽象数据类型 Verilog提供以硬件为中心的net和变量数据类型。这些类型代表4状态逻辑值,...
赋值操作 Verilog没有简单的方法可以对向量填充1。 parameter N=64;reg [N-l:0] data_bus;data_bus = 64' hFFFFFFFFFFFFFFF; //set all bits of data_bus to 1 sV可以通过’0,'1,‘z和’×来分别填充0,1,z和x。通过这种方法,代码会根据向量的宽度自动填充,这提高了代码的便捷性和复用性。 sv在...
