Abstract

Certain aspects direct to systems and methods for platform simulation for development projects of a management controller, such as a baseboard management controller (BMC). The management controller stores a firmware module and a simulator module. The firmware module is supposed to receive output signals from a computing device as the platform, or from one or more devices connected to the platform. The simulator module is a software implemented module used to simulate the platform or the device, by generating the output signals of the platform or the device based on configuration data stored in a data library, and sending the simulated output signals to the firmware module for development and testing purposes.
