Gem5 Fault Injector tool?

Hello everyone,

I am looking for a valid and working Fault Injector for gem5 with RISCV ISA for Full System simulation, which supports transient and permanent faults. Regarding the type of faults I have no stringent constraints, for sure I need software level faults (register faults, memory etc), but if possible it would be useful to have hardware faults as well.

Does anyone know of a Fault Injector that might be right for me?
