AI summary

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 thermal output signals from cooling zones of a computing device. The simulator module is a software implemented module used to simulate the cooling zones, by generating the thermal output signals of the cooling zones based on configuration data stored in a data store, and sending the simulated thermal output signals to the firmware module for development and testing purposes.
