EBMC
About EBMC
EBMC is a free, open-source formal verification tool for hardware designs.
It can read Verilog 2005, SystemVerilog 2017, NuSMV and netlists (given in
ISCAS89 format). Properties can be given in LTL or a fragment of
SystemVerilog Assertions. It includes both bounded and (despite its name)
unbounded Model Checking engines, i.e., it can both discover bugs and prove
the absence of bugs.

Documentation
The EBMC Manual describes the command line options of EBMC.
We also provide papers that provide background on how EBMC works:
- Hardware Verification using Software Analyzers
- Approximation Refinement for Interpolation-Based Model Checking
- Computational Challenges in Bounded Model Checking
- Computing Over-Approximations with Bounded Model Checking
- Efficient Computation of Recurrence Diameters

Benchmarks
To run ebmc on the benchmarks used at the hardware model checking competition 2008, use this script.
- vcegar-benchmarks.tgz
Features
- SystemVerilog assertions for property specification
- Bounded Model Checking (BMC) for bug finding and for generating coverage witnesses
- unbounded proof with k-induction engine
- unbounded proof with BDD engine
- unbounded proof with IC3 (many thanks to Eugene Goldberg)
Versions up to (including) 4.1 have also supported the following methods:
- Completeness threshold computation with structural analysis
- Cut-point abstraction with counterexample-guided refinement
- Model Checking using bit-level interpolation for approximate image computation
- Model Checking using word-level interpolation for approximate image computation
