Hi David,

I am sorry for late response. Here is the configuration I used to simulate
my NoC

./build/ARM/gem5.fast configs/example/fs.py --l1d_size=32kB --l1i_size=32kB
--num-l2caches 4 --l2_size=1MB --cacheline_size=64
--machine-type=VExpress_GEM5_V1 --kernel
/home/khilji/gem5/m5/system/binaries/vmlinux-aarch32 --disk-image
/home/khilji/gem5/m5/system/disks/arm-ubuntu-natty-headless.img
--dtb-filename /home/khilji/gem5/m5/system/dtb/armv7_gem5_v1_4cpu.dtb
--num-cpus=4 --ruby --num-dirs=4 --network=garnet2.0 --topology Mesh_XY
--mesh-rows 2 --mem-size 1GB --cpu-clock 1GHz --work-begin-exit-count=1
--work-end-exit-count=1

This is the configuration of 2x2 NoC. Each core has 1GB of memory (DRAM).
Total size of memory 4GB.
regards,

Sharjeel
