16{}这种记法是重复操作符(replication operator),即把括号内的内容按照前面的数字重复 << & >> / streaming operators / 流算符 终于进展到了主题,流出算符指的是对数组进行压缩或解压。在我们的例子中, {<<4{B[LEN*3 +: LEN]}} 指的是对数组B中高16位,按照4位来分割,形成一个长度为4的unpacked arr...
=一样,只是在比较器中会忽略被屏蔽的位,与Verilog的casex语句遵循相同的综合规则与限制。 5.2.2集合成员关系运算符(inside) Set membership operator (inside) 集合成员关系运算符inside将一个值与一个由{ }括起来的值列表进行比较。数值列表中的值可以是由[ ]指定的一个值范围,也可以是某个数组中所存储的值。
