Internship: Combining Analytical and ML Models for Efficient HW Performance Prediction - Saclay H/F

Using the CVA6, CVA6S, CVA6S+ architectural evolution as a case study, the internship will explore:

• Hybrid modeling: Combining simulation ML-driven performance insights with analytical architectural models.
• Transferability: Evaluating whether models developed for one hardware generation can be adapted to subsequent generations with limited retraining or recalibration.
• Design-space exploration: Assessing the ability of hybrid models to efficiently predict the impact of architectural modifications.

The internship aims to develop and evaluate a hybrid modeling methodology that balances accuracy, expressiveness, and transferability across hardware generations. The ultimate objective is to assess its potential for enabling flexible hardware design-space exploration, reducing reliance on costly cycle-accurate simulations.
