Hello, (1) What are the steps for integrating DRAMSim3 as the memory simulator to Gem5?
We added dramsim3 repository in ext/dramsim3 and built (scons -j4 build/VEGA_X86/gem5.opt) (2) After the integration, how do we invoke DRAMSim3 instead of the Gem5 memory model? It executes fine when I use gem5's memory model: build/VEGA_X86/gem5.opt configs/deprecated/example/se.py --cmd=tests/test-progs/hello/bin/x86/linux/hello But fails when I add the dramsim3 options: build/VEGA_X86/gem5.opt configs/deprecated/example/se.py --cmd=tests/test-progs/hello/bin/x86/linux/hello --mem-type=DRAMsim3 --dramsim3-ini=ext/dramsim3/DRAMsim3/configs/DDR4_8Gb_x8_3200.ini gem5 Simulator System. https://www.gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 version DEVELOP-FOR-25.1 gem5 compiled Jul 7 2025 19:20:40 gem5 started Jul 7 2025 19:43:24 gem5 executing on milan2.ftpn.ornl.gov, pid 1965880 command line: build/VEGA_X86/gem5.opt configs/deprecated/example/se.py --cmd=tests/test-progs/hello/bin/x86/linux/hello --mem-type=DRAMsim3 warn: The se.py script is deprecated. It will be removed in future releases of gem5. AttributeError: object 'DRAMsim3' has no attribute 'controller' (C++ object is not yet constructed, so wrapped C++ methods are unavailable.)

Thanks, *Kazi*
