Link for ModelSim

Coding VHDL Entities for MATLAB Verification

The most basic element of communication in the Link for ModelSim interface is the VHDL entity. The interface passes all data between ModelSim and MATLAB as port data. The Link for ModelSim works with any existing VHDL entity. However, when coding a VHDL entity that is targeted for MATLAB verification, you should consider its name, the types of data to be shared between the two environments, and the direction modes. The following sections cover these topics:

• Overview of the Steps for Coding VHDL Entities

• Choosing an Entity Name

• Specifying Ports for the Entity

• Specifying Port Direction Modes

• Specifying Port Data Types

• Sample VHDL Entity Definition
