提出了两种基于软件仿真法构建单片机虚拟实验室的方案，在线联合仿真和离线联合仿真，并通过对离线仿真的一个应用实例进行分析。构建虚拟实验室在一定程度上缓解了单片机实验室设备资金短缺和维护难的问题！-Proposed two kinds of software-based simulation method to build a virtual laboratory microcomputer programs, on-line co-simulation and offline co-simulation, and through off-line simulation of an application example for analysis. Construction of a virtual laboratory to some extent alleviated the shortage of funds microcomputer laboratory equipment and maintenance of the difficult problem!
