I am using gem5 version 22.0. I want to simulate hybrid memory comprising DRAM and NVM. I have written the code to simulate hybrid memory using heterogeneous memory controller as: system.mem_ctrl=HeteroMemCtrl() system.mem_ctrl.dram = DDR3_1600_8x8() system.mem_ctrl.dram.range = system.mem_ranges[0] system.mem_ctrl.nvm=NVM_2400_1x64() system.mem_ctrl.nvm.range =system.mem_ranges[1] print(system.mem_ranges[0]) print(system.mem_ranges[1]) But I am getting the error as the memory address range for nvm memory is overlapping, how can I assign continuous addressing to both memories?

Hi Sadhana, In the screenshot you shared, the address ranges assigned to two memory devices are overlapping (0:1073741824 and 0:2147483648). You should modify the second range such that it does not start from 0 but starts from 1073741824 or some other address (such that the two ranges do not overlap). -Ayaz On Wed, Sep 20, 2023 at 10:16 PM Sadhana . via gem5-users < gem5-users@gem5.org> wrote: > I am using gem5 version 22.0.
