Abstract

A system and method of communicating data acquisition and simulation signals are described. The system includes a plurality of networked nodes. Each node is connected to the other nodes using a reflective memory connection. The nodes include an input/output node configured to communicate test signals and a simulation node configured to receive signals from the input/output node and to generate simulation signals. The method includes communicating an acquired data signal from an input/output node to a simulation node using a reflective memory-based communication network and communicating a generated simulation signal from the simulation node to the input/output node using the reflective memory-based communication network.
