1.什么是VHDL中的数组? 数组是一种用于存储多个值的数据结构。在VHDL中,数组可以是一维、二维或多维的,并且可以包含指定数量的元素。 2.如何声明一个一维数组? 在VHDL中,可以使用以下语法声明一个一维数组: type array_name is array (range) of element_type; 其中,`array_name`是数组名称,`range`是数组的范...
In VHDL-87, bit-string literals may only be used as literals for array types in which the elements are of typebit. The predefined typebit_vectoris such a type. However, the standard-logic typestd_ulogic_vectoris not. We may use string literals for array types such asstd_ulogic_vector. ...
Hi, In VHDL, we can have something like this: TYPE memory1 is array (0 to 11) of std_logic_vector(7 downto 0); constant RVSeq: memory1 :=

A simple testcase with an unsigned array (see code below) shows that the GHDL simulator object of type NonHierarchyIndexableObject seems not indexable (tried hard code index 0, 1 and 2, all give the same error. Observations The same VHDL code is used for two VHDL simulators: nvc and ghdl...
