multidimensional(多维)打包阵列仍然是一组连续的位,但分段为多个更小的群组。 示例#1 以下所示代码声明的是一个占 32 位或 4 字节的二维打包阵列,它迭代经过各段并打印阵列值。 module tb; bit [3:0][7:0] m_data; // A MDA, 4 bytes initial begin // 1. Assign a value to the MDA m_data =...

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...

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. ...

Multidimensional Packed Arrays(多维压缩数组) 多维打包数组仍然是一组连续的位,但也被分成较小的组。 例子1 下面显示的代码声明了一个2D压缩数组,该数组占用32位或4个字节,并遍历各段并打印其值。 module tb; bit [3:0][7:0] m_data; // 32位,4个字节 initial begin m_data = 32'hface_cafe; $di...
