Hi Dr. Bruce,

Thanks a lot for the reply.

Setting the variable this way works, but only if I set it before the simulation 
starts completely. I looked at the source code and it seems 
max_insts_any_thread is only used to schedule an exit event in the 
BaseCPU::init() function. I’m guessing this is only called once at the very 
beginning. Is there a way to set the max instruction count when the simulation 
has exited (e.g., due to an m5 exit instruction) so that it runs for n 
instructions after this point?

Best regards,
Hossam

Board+Simulator API

Hey Hossam,

A better API for setting max number of instructions via the Simulator module 
will be coming in v22.1, but in the meantime you can do something like:

```
processor.get_cores()[0].get_simobject().max_insts_any_thread = <max insts>
```

With the above, the simulation will exit when any thread on the first core 
reaches the max number of threads.
