With the development of storage and server systems, board card integration and complexity are higher and higher. Communication interaction scenes among multiple ICs often appear on the same single board. As shown in fig. 1, in the prior art, after the server system is powered on in the normal state, the reset signal of the target IC comes from the master IC. When the interactive IC performs communication interaction with the target IC, the target IC is required to enter a ready state during the starting process of the interactive IC. However, the starting time of the main control IC cannot be controlled, and the reset signal sending time of the main control IC for the target IC in different batches is not fixed due to the manufacturing process, the process and the like. Therefore, when the sending time of the reset signal aiming at the target IC is later than the interaction time of the interaction IC and the target IC, the communication function between the interaction IC and the target IC is abnormal, and the normal communication interaction can be completed only by reloading the opposite side drive after the interaction IC and the target IC are reset, so that the reliability of the server system is reduced.
From the above, it can be seen that how to ensure the target IC is in a state of completing reset during the starting process of the interactive IC is a problem to be solved at present.
