Grammar for message passing in a distributed simulation environment

摘要

A distributed simulation system includes a plurality of nodes and a hub. Each node may simulate a portion of a system under test, or may execute a test program for the simulation. The hub may route message packets from one node to another. The message packets are formatted according to a grammar used by the distributed simulation system, which abstracts the physical signals of the system under test to logical ports. Additionally, some embodiments may include other commands, such as commands for configuring the distributed simulation system, describing the logical ports and logical signals within the logical ports, and mapping the logical signals to physical signals. A formatter program may be used in each node and the hub to format message packets for transmission, according to the grammar. A parser program may be used in each node and the hub to parse received message packets, again according to the grammar.
