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的元素数据...
在SystemVerilog 中,unpacked arrays独立存储每一个元素,如: wire[7:0]table[3:0]; 其存储形式如下: SystemVerilog 也允许 unpacked arrays 简化成 size 的形式: SystemVerilog adds C-like arraydeclarationsto Verilog, allowing unpackedarraysto be specified with a dimension size, instead of starting and en...
module fixedsize_array; //declaration of array's int array_1[4]; int t_sum; int t_product; initial begin //array initialization array_1 = '{1,2,3,4}; t_sum = array_1.sum(); //t_sum = 1+2+3+4 $display("Sum of array_a is \t %0d", t_sum); t_product = array_1....
as discussed in section 5.1.2 on page 98, values in the list are assigned to members of the structure. The packed structure is treated the same as an unpacked structure in this circumstance, rather than as a vector. The values within the ’{ } braces are separate values for ...
The use of the numbers was to make the rows distinguishable when in the packed format, i.e. bt3 is the packed format of the all 8 4-bit values in memory (the simulation's database) the declaration of an array is represented by the unpacked array: logic [#bits-1:0] bt1 [#rows-...
// A Verilog parameter allows to control the width of an instantitated // block describing register logic // // // File:parameter_1.v // module myreg (clk, clken, d, q); parameter SIZE = 1; input clk, clken; input [SIZE-1:0] d; output reg [SIZE-1:0] q; always @(posed...
SystemVerilog uses the term packed array to refer to the dimensions declared before the object name, and the term unpacked array is used to refer to the dimensions declared after the object name; a packed array is guaranteed to be represented as a contiguous set of bits, and an unpacked ...
