PolyCleaner

The paper introduces a verification method based on Symbolic Computer Algebra (SCA) and presents a new theory for the origin of vanishing monomials, redundant monomials which lead to an monomial explosion for non-trivial multipliers. The implemented SCA-verifier PolyCleaner is able to prove the correctness for non-trivial million-gate multipliers where the other state-of-the-art methods failed.

For PolyCleaner we received the Best Paper Award at the International Conference on Computer Aided Design (ICCAD) 2018.

RevSCA

RevSCA proposes a fast and robust SCA-based verification method integrating dedicated reverse engineering to verify big and dirty multipliers.

How to get RevSCA

• The binary of RevSCA and the benchmarks are avialable at GitHub!

Recently, we have improved RevSCA to also support signed multipliers and we have also optimized the implementation. This new version is called RevSCA-2.0.

How to get RevSCA-2.0

• The binary of RevSCA-2.0 and the extended set of benchmarks are avialable at GitHub!

DyPoSub

DyPoSub takes advantage of dynamic substitution ordering in combination with local vanishing removal and reverse engineering to verify optimitzed and industrial multipliers.

How to get DyPoSub

• We make DyPoSub available on GitHub soon.

GenMul

We present the multiplier generator GenMul, which outputs multiplier circuits in Verilog. The input size of a multiplier and each multiplier stage can be configured with GenMul. In addition, GenMul is open source under MIT-license to ease for adding new architectures. Overall, this allows to challenge formal methods as shown by experiments which compare recent verification approaches.

How to get GenMul

• The C++ code of GenMul is available at GitHub.
• If you just want to generate Verilog files you can also use the web-based version below. We have used the Emscripten toolchain to compile Javascript from our C++ implementation of GenMul.
