Description	In this paper, we introduce an interactive simulator for programs in the form of LLVM bitcode. The main features of the simulator include precise control over thread scheduling, automatic checkpoints and reverse stepping, support for source-level information about functions and variables in C and C++ programs and structured heap visualisation. Additionally, DivSIM is compatible with DiVM (DIVINE VM) hypercalls, which makes it possible to load, simulate and analyse counterexamples from an existing model checker, and with abstract bitcode generated by LART (LLVM Abstraction and Refinement Tool), making it suitable for direct analysis of abstract and/or symbolic programs and counterexamples.
