如何在 vhdl 中实例化具有可变大小端口的多个组件？
How to instantiate multiple components with variable size ports in vhdl?
我想反复详细说明几个用于生成语句的组件，这些组件具有可变大小的端口，我不知道如何将这些可变大小的端口分配给信号。
我正在使用带有此声明的包：
library ieee;
use ieee.std_logic_1164.all;
PACKAGE Arrays_package IS
type Generic_ARRAY_type is array (integer range <>) of std_logic_vector;
END Arrays_package;
下面代码中的组件是Pre_pre_buffer_conv和Pre_buffer_conv。
如何声明信号xdataout_preprebuffer？

我认为信号 xdataout_preprebuffer 必须声明为二维数组信号，但我不知道如何实现。
两个变化。
包中添加类型：
library ieee;
use ieee.std_logic_1164.all;
package arrays_package is
type generic_array_type is array (integer range <>) of std_logic_vector;
type generic_array_of_generic_type is -- ADDED type
array (integer range <>) of generic_array_type;
end package arrays_package;
和信号声明：
signal xdataout_preprebuffer: generic_array_of_generic_type -- type mark
-- index subtype:
(no_col_filt * no_bits - 1 downto 0)
-- element constraint (generic_array_type):
-- index subtype:
(no_col_filt - 1 downto 0)
-- element index constraint (std_logic_vector):
(no_col_filt * no_bits - 1 downto 0);
之后您的代码将进行分析（详细说明和模拟需要所有这些组件在详细说明期间绑定到的实体。使用实体声明和组件的虚拟架构主体，您的代码详细说明和模拟（显示关联和分配不没有边界错误）。
添加的类型与原始类型一样使用 -2008 无界数组定义（参见 IEEE Std 1076-2008 5.3.2 数组类型、5.3.2.1 常规、
5.3.2.2 索引约束和离散范围，6.3 子类型声明）。
我们得到的是一个无界一维数组类型(generic_array_of_generic_type)，它的元素类型(无界一维类型generic_array_type)有它自己的元素无界一维数组类型(std_logic_vector).无界数组类型的索引约束在对象声明期间提供。
