Key Findings at a Glance
RIFT redefines fault assessment for LLM accelerators by leveraging Reinforcement Learning to intelligently identify minimal, high-impact fault scenarios. This results in significant speedups and superior fault coverage compared to traditional methods. The framework provides actionable data for intelligent hardware protection strategies, leading to superior cost-effectiveness.
It's UVM-compliant, ensuring seamless integration into existing commercial RTL verification workflows.
RIFT Methodology Explained
RIFT transforms the complex search for worst-case faults into a sequential decision-making problem. It uses a three-phase approach:
Enterprise Process Flow: RIFT Framework
Phase 1: Vulnerability Profiling
→
Phase 2: Candidate Set Initialization
→
Phase 3: RL-Powered Test Vector Generation
→
UVM-Compliant Testbench Generation
This systematic approach, guided by RL, efficiently navigates the vast combinatorial fault space, moving beyond brute-force methods.
Performance & Scalability Deep Dive
RIFT significantly reduces computational cost and time for fault assessment. It achieves a 2.2x speedup over evolutionary methods and a >99% test vector reduction compared to random fault injection, all while ensuring superior fault coverage.
The framework demonstrates excellent scalability, with runtime growing linearly with the number of parameters in the target fault-sensitive hotspot (R² > 0.99).
