SystemVerilog 中有 2 种类型的阵列:packed(打包)和unpacked(解包)。 packed阵列用于表示在变量名称之前声明的维度。 bit [3:0] data; // Packed array or vector logic queue [9:0]; // Unpacked array packed阵列必然呈现为一组连续的位。这类阵列可由单位数据类型(如bit和logic)与其它递归打包阵列组成。

There are two types of arrays in SystemVerilog - packed and unpacked arrays. A packed array is used to refer to dimensions declared before the variable name. bit [3:0] data; // Packed array or vector logic queue [9:0]; // Unpacked array A pack
SystemVerilog constraints are powerful enough to be applied on multidimensional arrays as well. In the following example we have a multidimensional static array with a packed structure. Here we attempt to assign the pattern 0xF0F0F to each element of the multidimensional array. ...

SystemVerilog标准会将向量推断为压缩数组(packed array),以表示向量代表一个连续存储的bit数组。SystemVerilog还新增的一个重要功能:允许使用多个范围将向量划分为多个分区(subfields)。例如: 多维压缩数组,以及多位压缩数组的选择(selections within multidimensional packed arrays)是可综合的。当设计需要经常引用向量的某些...
