I just tried to synthesize some VHDL in Vivado 2019.1 to see if VHDL-2008 generic types are supported. I eventually got the VHDL to synthesize and implement. This is great, because in prior versions I wasn't able to get it to work. However there was one caveat. Here's the format I used to instant

Generic is a basic and very useful function of the VHDL. It allows creating more flexible and easy to modify components. Proper use of it will save your time and make your code clearer and more readable. How do they work? They allow easily changing structure and function of the component.

VHDL Entity representing a flip-flop type D with input port: clock and reset active low, data D, and output port Q. A port mode similar to inout used to connect VHDL ports to non-VHDL ports. literal: An entity class, to be stated during attribute specification of user-defined attributes. loop: Statement used to iterate through a set of sequential statements. map: With port or generic, associates port names within a block (local) to names outside a block Generic Large-capacity RAM Model The behavioural code presented in this model will enable you to create a large-capacity RAM model limited only by the virtual memory of your computer. When modelling large memories using VHDL, many users are disappointed by the limited sizes of RAM that they can create. Attached ModelSim VHDL design of Generic Decoder.

VHDL Syntax Reference (Author's Note: This document contains a reference on VHDL syntax that you may encounter during this course.It is by no means complete.There are many references available online that you may check for more complete material. The following is intended simply to provide a quick and concise reference on commonly used syntax in VHDL.)

Re: GENERIC's in VHDL GENERIC's in VHDL Generics allow a design entity to be described so that,for each use of that component,its structure and behavior can be changed by generic values.In general they are used to construct parameterized hardware components.Generics can be of any type.

I've been working on making a decoder that I can use in multiple instances by just changing a generic value for the size of the input/output vector. The decoder will 'sll' a single bit, a number of positions based on the integer conversion of the input.

exportable) subprograms, constants, and types are declared, and a "package body", in which the subprogram implementations are defined, along with any internally-used constants and types.

You can have a generic array of fixed width vectors though. You can take a function of a generic, but you can't declare a type/subtype based on the generic anywhere in the VHDL syntax. What do you think this is? C++ with templates? Ha! In VHDL, we define datatypes while initializing signals, variables, constants, and generics. Also, VHDL allows users to define their own data types according to their needs, and those are called user-defined data types.
