1. 维度在标识符前面的部分称为packed array,在标识符后面的部分称为unpacked array,一维的pakced array也称为vector。 packed array packed array只能由单bit数据类型(bit,logic,reg)、enum以及其他packed array和packed structure组成。packed array保证在内存中一定是一段连续的bit unpacked array unpacked array的元...
SystemVerilog 中有两种类型的数组- packed array 和 unpacked array。 packed array用于引用在变量名称之前声明的维度。 bit[3:0]data;// Packed array or vectorlogicqueue[9:0];// unpacked array packed array保证表示为一组连续的位。它们只能用于单位数据类型(如、和其他递归packed array)组成。bitlogic Sing...
