Automation Integrated Method Research And Application Of SSI&MSI

Integrated circuits are widely used in personal computers, mobile phones, smart appliances andother civilian areas; and military aviation satellites, ships, weapons control systems. Moore’s Law thelaw of development of integrated circuits, namely the number of components on an integrated circuitdoubles every18months, so the rapid development of integrated circuit technology to create avariety of equipment and instruments for rapid replacement.JianXin shipping companiesintroduction of foreign ship kiloton central instrument due toincreased working life, spare circuit board to save the poor, the central instrument run increasinglyunstable; while some circuit board assembly of the ship has been discontinued, buy spare fromabroad the higher cost of the board; while high domestic development to replace the circuit boardfailure rate, greatly affected the normal water operations and training ship. The instrument is a digitalsystem is composed of small and medium-scale integrated circuits and discrete components,integrated circuit technology well into the nanometer era, small-scale integrated circuits have beenmoved toward the middle and late life, a lot of TTL and CMOS-based chips have been discontinued,if the board chip is damaged, then the instrument will become extremely difficult to maintain, whichwill cause forced retirement.LSI and VLSIis leading the development direction of electronic technology, which is relativelyrepresentative of significance FPGA chip and ASIC. Programmable logic devices appear toaccelerate the design and development of speed, its application to improve the hardware stability,reliability and testability. Based on EDA technology and SOC technology, the thesis of the centralinstrument of the ship’s command system integration technology to automate research, optimize theoverall design of the system, the central instrument to improve the reliability and maintainability,reducing overall system power consumption. The key technology research and work done tocomplete the paper is as follows:(1) According to the central computer system of the ship commanded digital components andmore complex systems, etc., made up by the following integrated automation solutions.(2)the use of artificial methods to fine clock and delay completion of the integration can not beachieved automatically monostable circuit, RC delay circuit element description; using multi-inputAND gate to achieve the goal line OC and logic.(3)A circuit module division method based on a correlation matrix, the family-oriented productdesign module construction method to divide the introduction of the improved circuit module.Correlation established between the circuit and component design structure matrix quantization matrix, calculated reflecting strong logical relationship between elements reachable matrix, thematrix module is divided up according to the basis; central instrument file editing circuit board, forexample, conducted a module division method validation.(4) A discrete digital logic elements automation integration methods. According to the internallogic and sequential digital logic chip pins, set up as described in Verilog HDL component database;prepared automatically integrated analysis software Netlist-To-HDL, to achieve the automaticextraction of the table to be part of the network of digital integrated circuits, power supply signaland studied delete filter capacitor networks, logical analysis than the right, such as input and outputpins are automatically defined method.(5)On the address bus arbiter board to do automation integration, the integration of functions onthe ISE through simulation platform for automated integration method validation.
