Patent attributes
A system may implement a flexible architecture to allow designers and testers to use a single flexible system for testing during a transition from a computer simulated model to a physical working prototype via a bus (or protocol). As hardware components become available, the system may be updated to enable replacing a simulated component with a physical hardware component while continuing to leverage at least some existing parts of the system (e.g., software and/or hardware components including simulation). The system may use customizable application program interfaces (APIs) to interface with the different components, simulated or physical. The APIs may enable components to be “plugged in” to the system to create a different configuration. In some embodiments, API's and/or other simulation data may be stored in a library to enable reuse or modifications at different times.
