Abstract

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.
