How to increase the pipeline stages in the O3 CPU model?

[NewBoy23]

Hello everyone,

I've recently been diving into the O3 CPU model and currently, the model operates with a 5-stage pipeline. I'm curious if there is an existing interface or configuration that allows for easily increasing the number of pipeline stages in the O3 CPU model.

If such an interface does not exist, would the process involve manually adding and adjusting files akin to fetch.cc, fetch.hh, and other relevant components to expand the pipeline?

Any guidance, pointers to documentation, or examples from experienced users who have attempted this before would be immensely helpful. Thank you in advance for your time and assistance!
