1, Simulation Engineering management
Importing module 401 is realize the importing management function to device model description document, when testing crew selects certain device model, calling module 402 calls device model according to device model description document, building module 403 is combine to build to the device model existed in memory module to form the final artificial circuit needed, and generates the project file of the artificial circuit that this is built simultaneously.
