The value of a generic may be read in either the entity or any of its architectures. It may even be passed into lower-level components. Default values for generics may be given in an entity declaration or in a component declaration. generics may be set (via a generic map) in an instantiation, or a configuration

VHDL Generic. In VHDL, generics are a local form of constant which can be assigned a value when we instantiate a component. As generics have a limited scope, we can call the same VHDL component multiple times and assign different values to the generic. We can use generics to configure the behaviour of a component on the fly.

architecture RAMBEHAVIOR of RAM is. subtype WORD is std_logic_vector ( K-1 downto 0); --define size of WORD. type MEMORY is array (0 to 2**A-1) of WORD; -- define size of MEMORY Component Instantiation with Generics (positional association) Description Example instantiation_lable: component_name generic map ( signal_name | expression A port map is used to define the interconnection between instances. Syntax: port map ( [ port_name => ] expression, Description: A port map maps signals in an architecture to ports on an instance within that architecture. Port maps can also appear in a block or in a configuration.

This enables you to write parameterized design entities, such as an N-bit counter.

Here a Verilog parameter would be a generic constant declared in a generic clause and passed in a generic map. None of these are syntax errors, rather semantic errors. The package numeric_std_unsigned has operators defined allowing one operand to be of type natural.

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?

Generics are important enough to warrant their own example. They are used by the digital designer for two main purposes: Purpose #1: Create code that is flexible and easily reused. This might add a little bit of extra work up front, but it will decrease development time later on significantly. 2016-08-08 · Generic is a basic and very useful function of the VHDL.
