How accurate is PTLsim?
Very accurate. In every case where cycle accurate results could be affected, PTLsim implements key structures down to the register transfer level (RTL) in its model, yet still maintains high performance through its use of the novel algorithms and hardware accelerated techniques described above. PTLsim is highly configurable down to the very last bypass path or bit width. For an exhaustive list of user configurable structures, see the PTLsim User’s Manual and Reference.
