A semiconductor device and an operating method thereof are provided. An operating method of a semiconductor device, includes monitoring a plurality of request packets and a plurality of response packets that are being transmitted between a master device and a slave device; detecting a target request packet that matches desired identification (ID) information from among the plurality of request packets; counting the number of events of a transaction including the target request packet by using an event counter; counting the number of request packets whose corresponding response packets are yet to be detected, from among the plurality of request packets by using a Multiple Outstanding (MO) counter; determining whether an MO count value of the MO counter is valid; and if the MO count value is invalid, resetting the event counter.

Semiconductor device and operating method thereof

A semiconductor device and an operating method thereof are provided. An operating method of a semiconductor device, includes monitoring a plurality of request packets and a plurality of response packets that are being transmitted between a master device and a slave device; detecting a target request packet that matches desired identification (ID) information from among the plurality of request packets; counting the number of events of a transaction including the target request packet by using an event counter; counting the number of request packets whose corresponding response packets are yet to be detected, from among the plurality of request packets by using a Multiple Outstanding (MO) counter, determining whether an MO count value of the MO counter is valid; and if the MO count value is invalid, resetting the event counter.

An operating method of a semiconductor device includes monitoring multiple request packets and multiple response packets that are being transmitted between a master device and a slave device. A target request packet that matches predefined identification (ID) information is detected from among the request packets. An operation of a latency counter is initiated. The operation is for measuring the latency of a communication exchange (transaction) that includes the target request packet and a target response packet that is one of the response packets that matches the predefined ID information. The target response packet is detected from among the response packets. The operation of the latency counter is terminated. A latency value of the communication exchange is acquired from the latency counter.
