Hello,
I am working in gem5 for my final year project. I need to implement DVFS
approach to the garnet network to each of the routers in the network. But
as a first step i tried to implement DVFS to a topology first. I ve
included the code bit that i modified in the garnet_synth_traffic.py file,
to include dvfs. When i run the simulation in the config.ini file, i am
getting the output as dvfs=enabled. But when i try to read the power
Statistics using the on-chip-network-power-area.py file, i am getting an
error message. i am including the screenshot of the error message too. Can
someone please tel me how to correct this? Kindly help me.
THIS IS THE ERROR THAT I GET
python util/on-chip-network-power-area-2.0.py m5out/dvfs

THIS IS THE MODIFICATION IN GARNET FILE
# Create a seperate clock domain for Ruby
system.ruby.voltage_domain = VoltageDomain(voltage = options.sys_voltage)
system.ruby.voltage_domain = VoltageDomain(voltage =

voltage_domain =
system.ruby.voltage_domain,
domain_id = 0)
system.ruby.clk_domain.clock = ['1GHz','700MHz','400MHz','230MHz']
system.ruby.clk_domain.voltage_domain = system.ruby.voltage_domain
system.ruby.voltage_domain = VoltageDomain(voltage =
['1V','0.9V','0.8V','0.7V'])
system.ruby.clk_domain = SrcClockDomain(clock = options.ruby_clock,
voltage_domain =
system.ruby.voltage_domain,
domain_id = 1)
system.ruby.clk_domain.clock = ['1GHz','700MHz','400MHz','230MHz']
system.ruby.clk_domain.voltage_domain = system.ruby.voltage_domain
system.dvfs_handler.domains = system.ruby.clk_domain
system.dvfs_handler.enable = 1
Thank You
