Hi, Thanks for the inputs. It is working with the normal LRU cache by making it FA. I am not sure what the issue with FALRU is?

Anyway, my idea would be for that if the FALRU isnt working, why not edit the cache_builder code to just use the regular LRU cache? That code is updated and there should be know difference between using say 1 set with 8192 ways or 2 sets with 4098 ways.
