OldSpot is a simulation framework for estimating the lifetime of an SoC at the architectural unit level with support for failure tolerance. It can simulate heterogeneous systems with different types of cores (i.e. general-purpose cores or application specific accelerators) and resources shared among them such as last-level cache. For more detailed information on OldSpot, please refer to:

  • A. Roelke, X. Guo, and M. R. Stan, "OldSpot: A Pre-RTL Model for Fine-grained Aging and Lifetime Optimization." In Proceedings of the 36th IEEE International Conference on Computer Design, October 2018.
  • Chapter 3 of A. Roelke, "Improving Reliability and Security with Aging and Pre-RTL Modeling." PhD Thesis, University of Virginia, 2018.

OldSpot also incorporates device-level models which it uses to compute the aging of each microarchitectural units. It includes models for negative bias temperature instability (NBTI), electromigration (EM), hot-carrier injection (HCI), and time-dependent dielectric breakdown (TDDB).
