The device is : cyclone V 5CEFA9F31I7
The quartus version is 13.0
The fitter often failed and report the following message:
Error (170143): Final fitting attempt was unsuccessful
Info (170138): Failed to route the following 1 signal(s)
Info (170139): Signal "ctl_nios:ctl_nios_i|ctl_sopc:ctl_sopc_i|ctl_sopc_ control:control|data_out[0]~CLKENA0"
Info (170140): Cannot fit design in device -- following 1 routing resource(s) needed by more than one signal during the last fitting attempt
Info (170141): Routing resource Internal Device Resource (X46_Y46, I3)
The reported signal is a global signal. It seems that one global signal cant route, or conflict with other global signals
I have compiled the project many times. The fitter always failed to route one global signal, but not the same global signals.
(The details shown at attached.)
I dont know why the fitter failed to route global signals(sometimes the fitter succeed). And how can I solve the problem?
