Specifies the name of the simulation top-level unit. It can be a VHDL configuration or an entity, a Verilog module or configuration, a SystemVerilog program, a SystemC module, or an EDIF cell. A VHDL entity can be followed by the name of an architecture.

Configurations have been part of the VHDL standard since the first version of the language. But still, many FPGA designers never use them, perhaps because few people understand how configurations work. I find that unfortunate because it’s really not that complicated. Therefore, I will give my best shot at explaining how configurations work and how you can benefit from using them. The example design

The configuration specification is less hectic task of the code. The generic map and port map clauses are also used in configuration specification. The Syntax is : Example : entity INV_ERTER is generic (Propagation_delay : TIME := 5 ns); port ( IN1 : in BIT; OUT1 : out BIT); end INVERTER; architecture STRUCT_Inv of INV_ERTER is begin OUT1 <= not Which already seems to indicate that Modelsim doesn't properly support these configuration statements. There is no 'properly' that can be applied to your conclusion, which isn't supported by the VHDL standard. The error appears to have been caused by an attempt to elaborate Half_Adder when I2 is not bound. A configuration declaration defines how the design hierarchy is linked together during elaboration, by listing the entities and architectures used in place of each component instantiation within an architecture. A simple configuration contains reference to only one architecture body.

1) Your configuration works and 2) there are alternative tools where configuration works properly.

Directed Testing. Swapping between different directed test architectures is a good use of configurations. When writing simulations, the same port map can be used to design many directed tests. The simulation can choose the desired directed test to execute using configurations.

A package in VHDL is a collection of functions, procedures, shared variables, constants, files, aliases, types, subtypes, attributes, and components. A package file is often (but not always) used in conjunction with a unique VHDL library.

Simulation is what resembles most the execution in other programming languages. Synthesis translates a VHDL program into a network of logic gates. Many VHDL simulation and synthesis tools are parts of commercial Electronic Design Automation (EDA) suites.

Overview. In the software world, documentation tools abound. Doxygen, javadoc, kdoc and others allow to extract specially formatted comments from source code and generate a set of interlinked HTML pages giving the annotated class Configuration.

library. Burcin PA K 2 0 0 0 VH D L Syn A package in VHDL is a collection of functions, procedures, shared variables, constants, files, aliases, types, subtypes, attributes, and components. A package file is often (but not always) used in conjunction with a unique VHDL library. Packages are most often used to group together all of the code specific to a Library. Note that there is a third method of instantiation: configuration. That’s an advanced VHDL feature which I will cover in a separate article.
