Hi Mahyar, Thanks for your answer.
When I create a system by using a python script, does the system can be set randomly because Garnet standalone mode do not need to generate a system?

The PyTrafficGen object has several functions that generate the traffic you want such as createLinear, createRandom, createDram, createIdle, createExit. Then you can call the start function from PyTrafficGen on the traffic you have created. I think there is a script in configs/dram/sweep.py that has an example of using PyTrafficGen. Please let me know if you have any questions.

I have tried to run TrafficGen.py by command “python TrafficGen.py” but receiving error “ImportError: No module named m5.params”. I also tried compile traffic_gen.cc by command “g++ traffic_gen.cc -o traffic_gen” but fail again with message “traffic_gen.cc:37:10: fatal error: cpu/testers/traffic_gen/traffic_gen.hh: No such file or directory 37 | #include "cpu/testers/traffic_gen/traffic_gen.hh"”. Then I change the relative path to absolute path of header but the dependency of other files trigger other errors again, such as “traffic_gen/base.hh:45:10: fatal error: base/statistics.hh: No such file or directory 45 | #include "base/statistics.hh"”. Then, I switch to read gem5 description for Tracing and traffic generation in http://www.m5sim.org/General_Memory_System#Tracing_and_traffic_generation<https://apc01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.m5sim.org%2FGeneral_Memory_System%23Tracing_and_traffic_generation&data=04%7C01%7Cdaitr616%40student.otago.ac.nz%7Cc01f10b51b974e03d5a008d921e8dc6a%7C0225efc578fe4928b1579ef24809e9ba%7C1%7C0%7C637578106302857558%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=Y7woTDhDqxj7sJ2jCDm5MeGX8eLHwQv3ZsBdxPPmS3c%3D&reserved=0> and http://pages.cs.wisc.edu/~swilson/gem5-docs/classTrafficGen.html#a53b678d216bdfcf5097c0f0436c16e30<https://apc01.safelinks.protection.outlook.com/?url=http:%2F%2Fpages.cs.wisc.edu%2F~swilson%2Fgem5-docs%2FclassTrafficGen.html%23a53b678d216bdfcf5097c0f0436c16e30&data=04%7C01%7Cdaitr616%40student.otago.ac.nz%7Cc01f10b51b974e03d5a008d921e8dc6a%7C0225efc578fe4928b1579ef24809e9ba%7C1%7C0%7C637578106302867554%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=n8VNxwcLTnFq3nCrW6BQstUi6qRVzUQGv8AZrXNgzV4%3D&reserved=0>. The former website says traffic generator is controlled by a text-based configuration file, as can be seen in tests/quick/se/70.tgen/tgen-simple-mem.cfg . But when I go to the directory gem5/tests, there is no such kind of file. The latter website tells functions of related code but it seems outdated. My expectation is that using TrafficGen.py manually define which cpus send packets, how big they are, and which cpus receives packets and generate traffic. Then feed them to Garnet standalone debug mode to test network performance. Does anyone know how to solve this problem or give me some pointers/tutorials. I appreciate it very much!
