Airworthiness Design Of Data Bus On Chip Which Based On AMBA Protocol

With the rapid development of electronic design,more and more new general electronic design and verification methods begin to enter the field of civil aviation because of its outstanding advantages,such as the SoC design method,therefore the aviation industry and bureau of civil aviation have pay attention to the airworthiness design and verification of product which use such new design methods.In this paper,we have studied the airworthiness of data bus on chip and and general IP which based on SoC design method.First,paper introduces DO-254 and the principle and advantages of SoC design method,then paper emphasizes the characteristic of data bus on chip and general IP.After that,paper proposes the design of data bus and multi-channel aviation bus transceiver IP which based on AMBA protocol and follow the DO-254,then using the safety assessment method to analysis the safety of the design and integrated the safety requirements into the design which come from the safety assessment process,and completes requirements acquisition,conceptual design,detailed design and so on.In the validation section,the paper focuses on building the advanced verification platform in SystemVerilog which is seen as a reusable verification,completing the function verification of the design by this verification platform,and recharifing the principle of the design which indicate in previous content of the paper.Finally,the correctness and integrity of the design and verification work are demonstrated by the advanced verification methods such as the element analysis and CDC analysis.In the end the paper makes a summary of the research on the suitability of airworthiness by using AMBA protocol to design the data bus on chip which carrys a multi-channel aviation bus transceiver IP.It includes using safety assessment and requirements,in accordance with the DO-254 guide for the development of the hardware life cycle,and using the advanced verification method to verify and assess the design and results,and finally the paper plans the next work in the future.
