Hi Abdelrahman, The TLB is part of the MMU, which is a submodule of the CPU. These values are specified in the architecture specific source files -- so in your case, src/arch/x86/X86MMU.py is where the itb and the dtb are declared. In that file you'll see that the specs for these caches are defined there.
Note that if you change these features here, then you will need to recompile gem5 for them to actualize in your simulation, but it seems as though the are parameterized, so you can take advantage of that when the constructors are called. I hope this helps! Best, Sam On Wed, Aug 10, 2022 at 1:53 AM Abdelrahman S. Hussein <abdelrahman.sob...@gmail.com> wrote: > > Hello, > > I am running an x86 Full System Simulation.
