ICD designing method independent of network

Abstract

The invention discloses an ICD (interface control document) designing method independent of a network. The ICD designing method independent of the network includes the following steps: a step 1: acquiring packaging rules of various network buses needing to be used; a step 2: inputting parameters and attribute information which need to be transmitted by a device to an application layer ICD; a step3: selecting a network bus needing to be used, and using the packaging rule corresponding to the network bus to define the application layer ICD; and a step 4: generating a physical layer ICD file. The ICD designing method independent of the network starts with the device application layer, analyzes differences of various network bus protocols, and forms the packaging rules of various network buses, can automatically package the application layer ICD through a software tool, and can perform automatic conversion to acquire the physical layer ICD. The method can improve the usability of device interface data between cross-project types, can shorten the ICD designing time, and can greatly enhance the readability of a device interaction relation.

Description

technical field [0001] The invention relates to the technical field of ICD design, in particular to a network-independent ICD design method. Background technique [0002] 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 interface data between subsystems / equipment, and is an important component of the top-level design of the system. part. ICD design can be roughly divided into bus definition, data block definition, signal definition, and bit field definition from top to bottom. [0003] The traditional ICD design method is to define the bus signal and bus data block according to the agreement on the basis of familiarity with the network bus protocol. Negligence, resulting in a high error rate and not easy to be found; in addition, after changing the bus type across engineering models, the inte...

[0003] The traditional ICD design method is to define the bus signal and bus data block according to the agreement on the basis of familiarity with the network bus protocol. Negligence, resulting in a high error rate and not easy to be found; in addition, after changing the bus type across engineering models, the interface data of the device itself has not changed, but it is often necessary to redefine the ICD data packet applicable to the new bus protocol, resulting in Poor follow-up of previous work results
