Abstract

The invention discloses an equipment modeling language based embedded type emulated serial port and a modeling method thereof. Functional logic sends data to an exterior or sends external data to user interaction control logic or data processing control logic; the user interaction control logic obtains the external data, sends the external data to the data processing control logic, time sequence control logic or functional logic, receives the data sent by the functional logic or the data processing control logic and then displays the data; comprehensive processing logic and interface adapting logic realize data interaction of each logic; the data processing control logic performs format conversion for the data and then sends the processed data to the time sequence control logic, the user interaction control logic or the functional logic; and the time sequence control logic receives the data and sends the data to the functional logic according to a control time sequence. According to the equipment modeling language based embedded type emulated serial port and the modeling method thereof, as an embedded type hardware serial port is subjected to logic modeling and functional decomposition, the problem in the prior art that the logic level is lack of description for an embedded type hardware serial port simulation modeling method is solved.

Description

technical field

[0001] The invention relates to an embedded simulation technology, in particular to an embedded simulation serial port and a modeling method based on a device modeling language. Background technique

[0002] Embedded software refers to software that runs on special embedded hardware devices (such as mobile phones, various spacecraft, etc.). The early development and testing of these softwares usually rely on virtual hardware platforms (or emulators, both of which have the same meaning in this article). Taking the full digital simulation test environment as an example, it is a virtual hardware platform that uses software to simulate real hardware. Embedded software developers and testers can use this platform to run and test embedded software. The use of this virtual hardware platform , so that the development and testing of embedded software get rid of the dependence on real hardware.

Embodiment Construction

[0031] Aiming at the deficiencies of the prior art, the present invention proposes an embedded simulation serial port and a modeling method based on a device modeling language based on the requirements of embedded serial port hardware simulation, and adopts a new type of transaction-oriented simulation device modeling language, Functional simulation of various types of serial port hardware that appears in embedded hardware system simulation, the main problems to be solved can be summarized into the following two aspects:

[0032] (1) Embedded serial port hardware function emulation

[0033] Carrying out functional simulation on embedded serial port hardware refers to using software to simulate real embedded serial port hardware. The simulated serial port is mainly used in some complete embedded hardware simulation platforms as some plug-ins to provide serial port function simulation for use together; or used alone to realize serial port function simulation. To use this emulat...
