variable_name = array_name[index]; 3.2数组元素的赋值: 常数数组中的元素可以通过索引操作进行赋值。例如,如果我们定义了一个常数数组array_name,并想要将索引为index的元素赋值为new_value,则可以使用以下语法: array_name[index] = new_value; 3.3数组的遍历: 常数数组的遍历可以通过使用循环结构完成。通过循环...
方法:通过TYPE定义个matri_index的数组,数组包含50个数据,数据位数为16;申明了receive_data和send_data两个matri_index的数据。 --define a 16 bit array constant matrix_num: integer := 49; TYPE matrix_index is array (matrix_num downto 0) of std_logic_vector(15 downto 0); ...
matrix_index is array (matrix_num downto 0) of std_logic_vector(15 downto 0);signal receive_data, send_data: matrix_index;signal send_cnt: STD_LOGIC_VECTOR(7 downto 0);BEGIN process(clk,reset_n) --循环变量定义并初始化 variable i: integer := 0; ...

SystemVerilog provides system functions to return information about a particular dimension of an array variable or type. The return type is integer, and the default for the optional dimension expression is 1. The array dimension can specify any fixed sized index (packed or unpacked), or any dyna...
Verilog Array Operations Verilog arrays support many more operations than their traditional Verilog counterparts. +: and -: Notation When accessing a range of a Verilog array slice, we can specify a variable slice by using the [start+: increment width] and [start-: decrement width] notations. ...
