  1. The chip simulation network laboratory system this paper disguessed is a distribute network simulation system based on lan. the system ' s architecture is a c / s of three lays. the front platform are the chip simulation network system application program terminer ; the middle lay is a dcom server, it ' s duty is to deal with the communication and data transmission between the terminer and then database server, and to execute the logical operation. the application program just connect with the middle lay and get data from it, the connection and operation with database server will be managed by the dcom server. the duty of database server is to access and backup the final data

    具體是由位於網路各個終端的晶元模擬網路實驗系統應用程序為前臺；中間層為dcom應用程序服務器，負責處理前臺應用程序與后臺數據庫的通信和數據傳輸，並執行業務邏輯，前臺應用程序只需要與應用程序服務器建立連接，在中間層操作數據即可，與后臺數據庫的連接和操作由應用程序服務器來統一管理操作。后臺數據庫只負責數據的存取操作。本論文實施的晶元模擬網路實驗系統模擬了主要的邏輯電路器件， 8088cpu ，存儲器，寄存器，數據總線，地址總線和控制總線，及其它相關晶元。
