The invention discloses an espi controller verification system and method. The system includes an on-chip host, a controller module and a communication model simulating an off-chip host. The controller module includes at least one espi controller, wherein: the communication The model is configured to: generate corresponding communication data based on a preset communication handshake protocol; the on-chip host is configured to: process the communication data based on the communication handshake protocol to obtain corresponding result data; the control A controller module, configured to: transmit the communication data generated by the communication model to the on-chip host, return the result data obtained by the on-chip host to the communication model, and use the communication data generated based on the communication model and the corresponding result data to realize the functional verification of the controller module. The present application can avoid the situation that the on-chip host and the off-chip host cannot realize normal data interaction due to the failure of the controller module.
Description
technical field [0001] The invention relates to the technical field of device function verification, and more particularly, to an espi controller verification system and method. Background technique [0002] For the espi controller that realizes the espi (enhanced serial peripheral interface, serial peripheral interface) bus control in the prior art, it is usually required to receive the communication data of the off-chip host, and transmit the received communication data to the on-chip host through the espi bus for processing. , and the result data obtained by the on-chip host processing communication data is sent to the off-chip host through the espi bus to complete the data exchange between the off-chip host and the on-chip host. Therefore, if the espi controller is faulty, the off-chip host and the on-chip host may not be able to achieve normal data interaction through the espi controller. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to pr...
