# This configuration shows a simple setup of a TrafficGen (CPU) and an
# external TLM port for SystemC co-simulation
#
# Base System Architecture:
# +-------------+ +-----+ ^
# | System Port | | CPU | |
# +-------+-----+ +--+--+ |
# | | | gem5 World
# | +----+ | (see this file)
# | | |
# +-------v------v-------+ |
# | Membus | v
# +----------------+-----+ External Port (see sc_port.*)
# | ^
# +---v---+ | TLM World
# | TLM | | (see sc_target.*)
# +-------+ v
#
# Create a system with a Crossbar and a TrafficGenerator as CPU:
system = System()
system.membus = IOXBar(width = 16)
system.physmem = SimpleMemory() # This must be instanciated, even if not needed
system.cpu = TrafficGen(config_file = "tgen.cfg")
system.clk_domain = SrcClockDomain(clock = '1.5GHz',
voltage_domain = VoltageDomain(voltage = '1V'))
# Create a external TLM port:
system.tlm = ExternalSlave()
system.tlm.addr_ranges = [AddrRange('512MB')]
system.tlm.port_type = "tlm"
system.tlm.port_data = "memory"
# Route the connections:
system.cpu.port = system.membus.slave
system.system_port = system.membus.slave
system.membus.master = system.tlm.port
# Start the simulation:
root = Root(full_system = False, system = system)
root.system.mem_mode = 'timing'
m5.instantiate()
m5.simulate() #Simulation time specified later on commandline
