Demand based system ICD design method

Abstract

The invention belongs to the scope of ICD (Interface Control Document) design methods and provides a demand based system ICD design method. The demand based ICD design method comprises a first step of capturing an interface demand and interaction relationship between a system and a participator through demand analysis modeling operation to form a logic ICD of the system; a second step of converting the logic ICD into a device interface demand database by utilizing a demand management tool; a third step of mapping device parameters in an ICD design and management tool with device parameters in an interface demand database to realize automatic correlation of the device parameters; a fourth step of defining a device input and output interface signal and packaging the device parameters to a signal bit field and packaging the signal into a data block to finish the physical-layer ICD design of the device; and a fifth step of obtaining an ICD containing device parameter attribute information through an automatic exporting function.

Description

technical field [0001] The invention belongs to the category of ICD design method and relates to the ICD design process of all complex systems. Background technique [0002] Such as figure 1 As shown, the interface control document (Interface Control Document ICD) design is one of the core tasks of the model work. It is a technical document that defines and describes the functions, transmission characteristics and instructions of the interface data between subsystems / equipment. It is the top-level design of the system. important parts of. ICD design can be roughly divided into bus definition, data block definition, signal definition, and bit field definition from top to bottom. [0003] Traditional ICD design methods generally use manual input of device parameters, signals, and data block information, while device parameters and their attribute information are used to describe signal content and are only encapsulated in the signal layer, which is not the information concer...

Problems solved by technology

[0003] Traditional ICD design methods generally use manual input of device parameters, signals, and data block information, while device parameters and their attribute information are used to describe signal content and are only encapsulated in the signal layer, which is not the information concerned by the physical layer ICD. The number of them is often the largest among the three, which consumes a lot of manpower and time in ICD design, with low efficiency and high error rate, and it is not easy to modify and upgrade uniformly

[0004] At present, in the system design work, demand-driven design is adopted to carry out demand modeling analysis and architecture design, and finally form itemized requirements such as equipment functions, performance, and interfaces, but there is no continuous application, so that the previous work results have not been effectively implemented. inheritance and transmission
