I fail to operate this platform, I am sending the file top.cc (which contains
the description of the MIPS architecture) and the file plf_intr.h. This error
message is displayed during simulation:
[GDB] CPU0 (cpu0) cycle: ................ PC: bfc0039c FAULT: bad address.
end I not find words to thank you for your help.
