Abstract: A test method and a multi-processor SOC chip are provided. The method includes: parsing a first command line in a host system input buffer by a host system to obtain a first command and a first parameter corresponding to the first command line, when the first command is a command of the host system in a host system command set, executing the first command by the host system, and when the first command is a command corresponding to a subsystem, sending, by the host system, the first parameter to a subsystem input buffer corresponding to the subsystem as a second command line; and parsing the second command line by a subsystem to obtain a second command and a second parameter corresponding to the second command line, and when the second command is a command in a subsystem command set of the subsystem, executing the second command by the subsystem.

Abstract: A connection analysis method for a multi-port nested model and a medium. The method includes: acquiring instance information and nested relationships of a multi-port nested model, and building an instance relationship tree; reading port information and connection information of instances, and adding the port information and the connection information to the instance relationship tree; acquiring the port information and the connection information of the instances of each node layer by layer according to the instance relationship tree to build a connection dictionary; and acquiring port-to-port connection information of the instances by retrieving the connection dictionary to perform connection analysis on the multi-port nested model.
