Research on Hardware Interface Modeling Method Based on SysML

With the development of complex hardware systems, traditional interface design methods face many challenges in multi-domain collaboration and information consistency. In this paper, a hardware interface modeling method based on SysML (Systems Modeling Language) is presented, which can formally express the hardware product architecture, hardware interface composition, interface cross-linking relationship and other information through SysML model elements. Combined with the graphical modeling ability of SysML, the standardized design and rapid iteration of hardware interfaces can be realized. This paper also validates the effectiveness and feasibility of the method through a specific case.
