I have been thinking about functions in VHDL. If we have a function we could have both a function where we pass a "generic" (i.e. a fixed parameter known at compilation time) and a variable/signal (which contents is know at "execution" time).

Vhdl multiple generics

That’s a great question! I see you have stumbled upon a problem that many VHDL engineers before you have struggled with. There are several ways to handle this. You can give the generic a default value like this: generic(DataWidth : integer := 8); If you don’t assign anything to this generic when instantiating the module, the default value is chosen. In the VHDL below there are three generics.

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.

Development) develops software components for multiple domains, including experience in ASIC Verification ASIC/FPGA verification SystemVerilog/VHDL

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. Generic vhdl design with multiple drivers.

VHDL features include generics, packages of constants, generate statements, unconstrained arrays, VHDL attributes, block statements for inline-design partitioning, record data types for data bundling, configuration specifications, the ability to tie ports off to known constants, the ability to leave unused output ports open and unconnected, array aggregates, functions, and procedures.
