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. 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. The rules regarding different combinations of these are complex: see " VHDL " by Douglas Perry, page 218.

I have been thinking about functions in VHDL.

Vhdl multiple generics

Let us understand the use of "generic" with an example. vhdl generics Hi, As you have mentioned, Generic can be declared in entity. This is basically useful when you make multiple instances of a component. In case of multiple instances of a component you can have different value of generic for each instance. Lets take an example: This set of VHDL Multiple Choice Questions & Answers (MCQs) focuses on “Generics”. 1. In which part of the VHDL code, generics are declared?

VHDL allows the designer to parametrize the entity during the component instantiation. Imagine you need to write 2 RAM modules. VHDL generic example for two similar RAM entity. The RAMs are similar. Have the same interface in terms of signal but different access time address and BUS width.

How do they work? They allow easily changing structure and function of the component. it uses the entity generics (possible by instantiating it in the architecture head) AND; its contents are available in the entity declaration (possible by instantiating it on the file level, before the entity) So it seems like a dead end. Is there any way (maybe using VHDL-2019) to do what I'm trying to accomplish?

Mar 22, 2012 Usually, people use VHDL configurations to select a given architecture for their component, or even to set generics that were not set in the  Multiple architectures can be defined for the same entity. VHDL configurations can be Shown below is an architecture block for a generic decoder: architecture  statements used this way is that the same signal can be driven by multiple generate statements.

Have the same interface in terms of signal but different access time address and BUS width. In this case, there is no need to write twice the same module. Using Parameterized Functions and Generics (VHDL) In VHDL, you can create and use parameterized functions, including library of parameterized modules (LPM) functions supported by the Quartus II software. To create a parameterized logic function in VHDL, the logic function's Entity Declaration must include a Generic Clause that lists all parameters VHDL Generic.
