Semiconductor device and operating method thereof

An operating method of a semiconductor device, comprising:

• monitoring a plurality of communication exchanges between a first Intellectual Property (IP) block and a second Intellectual Property (IP) block, which are provided in a System-on-Chip (SOC), and that each include a request and a responsive response to the request;
• receiving predefined first ID information and predefined second ID information from outside the System-on-Chip;
• measuring the latency of a first transaction that is one of the plurality of communication exchanges that matches the first ID information by using a latency counter;
• measuring the latency of a second transaction that is one of the plurality of communication exchanges that matches the second ID information by using the latency counter;
• and
• computing an average latency and a peak latency based on the measured latency of the first transaction and the measured latency of the second transaction, wherein the request in each of the plurality of communication exchanges includes a request packet and the responsive response to the request in each of the communications exchanges includes a response packet corresponding to the request packet and transmitted in response to the corresponding request packets;
• counting a number of request packets with corresponding response packets that are yet to be detected, in connection with the first and second transactions, by using a Multiple Outstanding (MO) counter;
• and
• determining whether the corresponding response packets have been detected, by using a Response Ordering (RO) counter.

A semiconductor device, comprising:

• a filtering module that detects a target request packet that matches predefined identification (ID) information from among a plurality of request packets that are being transmitted between a master device and a slave device;
• a configuration module that receives the predefined ID information and that provides the predefined ID information to the filtering module;
• a latency counter that measures the latency of a communication exchange including the target request packet and a target response packet that is one of a plurality of response packets that matches the predefined ID information and that is transmitted in response to the target request packet;
• and
• a control module that controls an operation of the latency counter and detects the target response packet from among the plurality of response packets,
• a Multiple Outstanding (MO) counter that counts a number of request packets with corresponding response packets that are yet to be detected, from among the plurality of request packets;
• and
• a Response Ordering (RO) counter that determines whether the corresponding response packets have been detected for the plurality of request packets.
