EverLost: A Flexible Platform for Industrial-Strength Abstraction-Guided Simulation Flavio M. de Paula, and Alan J. Hu Computer-Aided Verification: 18th International Conference (CAV 2006) Abstraction-guided simulation is a general framework for automatically harnessing, during simulation, information from abstraction and model checking. EverLost is our platform for industrial-strength abstraction-guided simulation. EverLost takes an RTL Verilog design and preimage/abstraction information from any BDD-based abstraction/model-checking tool, and automatically generates code that implements abstraction-guided simulation and directly compiles with the design under the widely-used Synopsys VCS simulator. The platform enables flexible exploration of abstraction-guided simulation --- different formal tools and guidance heuristics are easily inserted --- while providing the capacity, speed, and Verilog compatibility of a leading industry-standard tool.
