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 Single Dimensional Packed Arrays 一维压缩数组也成为向量。 moduletb;bit[7...
Packed and Unpacked arrays SystemVerilog使用术语 packed array来表示维度在对象名称之前的数组,使用术语 unpacked array来表示维度在对象名称之后的数组。 Packedarrays只能由单bit类型( bit, logic, reg, wire)和其他packed arrays组成。 Example - Packed Unpacked array module packed_unpacked_data(); // packed ...
3. What is the Difference between SystemVerilog packed and unpacked array? SystemVerilog中打包数组和非打包数组有什么区别? 打包数组(packed arrays)被视为连续的位串,适合表示硬件中的数据类型,例如位向量。非打包数组(unpacked arrays)更像是C语言中的数组,每个元素可以有不同的数据类型,适用于存储复杂的数据...
Packed + Unpacked Array 下面显示的示例演示了一个多维packed+unpacked数组。 moduletb;bit[3:0][7:0] stack [2][4];// 2 rows, 4 colsinitialbegin// Assign random values to each slot of the stackforeach(stack[i])beginforeach(stack[i][j])beginstack[i][j] =$random;$display("stack[%0...
Packed and Unpacked arrays SystemVerilog使用术语 packed array来表示维度在对象名称之前的数组,使用术语 unpacked array来表示维度在对象名称之后的数组。 Packed arrays只能由单bit类型( bit, logic, reg, wire)和其他packed arrays组成。 Example - Packed Unpacked array ...
packed arrays, structs, uniions composed of types bit and logic emumeration types (interpreted as the associated real type) types constructed from the following constructs: struct union(packed only) unpacked array typedef 下面是一些注意点:
- Packed & unpacked arrays, unions and structs allow greater abstraction and more concise coding. The new dynamic array types facilitate behavioral modeling and assist in the development of verification environments. Semaphores and mailboxes are sometimes used in advanced verification methodologies such as...
