Hello everyone,
In configs/example/ruby_random_test.py, I want to connect the CPU port and the
ruby system port (sequence) through a crossbar, but I encounter an error.
Original code:
tester.cpuInstDataPort = ruby_port.in_ports
TO:
system.dmux = NoncoherentXBar(forward_latency=1, frontend_latency=1,
response_latency=1, width=4)
tester.cpuInstDataPort = system.dmux.cpu_side_ports
system.dmux.mem_side_ports = ruby_port.in_ports
I got the following error:
fatal: Unable to find destination for [0x3fec:0x3fed] on system.dmux
I don't know if the address ranges are inconsistent between the crossbar and
the ruby.
If anyone ever connects a crossbar to the rubyport, please help me with this.
Regards,
Wilson_______________________________________________
