Use gdb server in simulation?

[Kamyar Mohajerani]

Hi everyone!
Is it possible to attach gdb to a simulated OpenPiton model?

I'm using Ariane cores and Verilator.

Any feedback/pointers is greatly appreciated!

Best,

Kamyar

Hi Kamyar,

I'm sure it's possible to modify the simulation environment for this but it's not currently part of the system. The JTAG wires are there and I think Michael's intent was that this could be connected to spike or openocd somehow. I haven't dealt with it before though because the simulation environment already gives far more introspection capability via waveforms, instruction trace logs, and monitor prints than gdb does alone. I think Ariane's standalone simulation environment uses the debug spec for loading and that process slows down simulation a lot because of the need to simulate the cycles of loading the program before executing. It's a tradeoff really. How keen are you to have this?

Thanks,

Jon
