A general output method of digital quantity in simulation platform

Abstract

The invention provides a universal output method for the digital quantity of a simulation platform. According to the method, firstly, the description of initialize settings is defined, wherein the initialize settings are composed of the sending mode, the pulse width, the pulse number, the level state, the signal triggering delay time and external signal synchronous setting parameters. After that,whether a sent enabling or synchronizing signal is valid or not is judged. A corresponding high-low level output, a positive and negative single pulse output, a limited number of pulse output and a continuous pulse output are generated according to the parameter configuration information after the corresponding time delay time is waited. According to the invention, the unified description of digital quantity output signals is achieved. The defect that a traditional digital quantity output method is poor in universality, long in development period and high in cost can be overcome. The method has the advantages of normative performance, high reusability, short development period and low cost.

Description

technical field [0001] The invention relates to a general output method for digital quantities of a simulation platform, which belongs to the technical field of signal simulation. Background technique [0002] Embedded systems have a specific hardware operating environment, so the debugging and testing in the software development process are closely related to hardware timing and need to rely on simulation platforms. The traditional simulation platform is customized and developed for the real target system and its application scenarios, and it is a special test equipment with strong pertinence. However, in the face of the generally shortened software development cycle and the increasing number of agile development software, the traditional simulation platform has gradually exposed the following problems: [0003] (1) The hardware design scheme of the traditional simulation platform has poor versatility. It involves different developers, adopts different technical solutions...

Problems solved by technology

[0003] (1) The hardware design scheme of the traditional simulation platform has poor versatility

It involves different developers, adopts different technical solutions, and the functions and interface standards of various hardware boards are also different, making it difficult to reuse simulation platforms for different projects

[0004] (2) The traditional simulation platform has a long development cycle and high cost

The simulation platform of each new research project needs to go through the four processes of "design-production-debugging-use", which is difficult to meet the general shortening of software development cycle and the increasing application requirements of agile development software

[0005] (3) The traditional simulation platform has poor maintainability

Under normal circumstances, the on-orbit operation period of space-borne embedded software is 5 to 8 years, and some are even longer; during this period, the flow of platform developers will increase the risk of inadequate management of historical development data, resulting in new development. It is difficult for personnel to quickly and effectively maintain the simulation platform

[0006] (4) It is difficult for the traditional simulation platform to realize the generalization of supporting simulation software

There are differences in the hardware and onboard FPGA logic of different project simulation platforms, which directly affect the generalization of supporting simulation software
