AMulet 2.1 - AIG Multiplier Examination Tool

Our tool AMulet 2.1 is able to verify and certify unsigned and signed integer multipliers given as AIGs.

For further information we refer to the paper

Daniela Kaufmann, Armin Biere. AMulet 2.0 for Verifying Multiplier Circuits. In Proc. 14th Intl. Conference on Tools and Algorithms for the Construction and Analysis of Systems (TACAS), 8 pages, 2021.

and the corresponding website http://fmv.jku.at/amulet2

Dependencies: libgmp (https://gmplib.org/)

Use ./configure.sh && make to configure and build AMulet 2.1.

usage : amulet <mode> <input.aig> <output files> [<option> ...]

Depending on the <mode> the <output files> and <options> have to be set accordingly:

<mode> = -substitute:
  <output files> =  2 output files need to be passed in the following order 
    <out.cnf>:        miter for checking the equivalence of the substituted adder 
    <out.aig>:        rewritten aiger is stored in this file` 

  <option> = the following options are available 
    -h | --help       print this command line summary 
    -v<1,2,3,4>       different levels of verbosity  (default -v1)
    -signed           option for signed integer multipliers 


<mode> = -verify:
  <output files> =  no output files are required 
  
  <option> = the following options are available 
     -h | --help           print this command line summary 
     -v<1,2,3,4>           different levels of verbosity (default -v1) 
     -signed               option for signed integer multipliers    
     -no-counter-examples  do not generate and write counter examples
 
 
<mode> = -certify:
  <output files> =  3 output files need to be passed in the following order
    <out.polys>:      initial polynomial set 
    <out.proof>:      proof rules (depending whether PAC proof or NS proof is generated) 
    <out.spec> :      spec which should be checked 
  
  <option> = the following options are available 
     -h | --help           print this command line summary 
     -v<1,2,3,4>           different levels of verbosity (default -v1) 
     -signed               option for signed integer multipliers 
     -no-counter-examples  do not generate and write counter examples

     -p1          expanded proof (no linear combinations, only multiplication and addition)
     -p2          middle condensed proof(sequence of linear combinations, default)
     -p3          condensed proof(one single linear combination)

10.09.2021 AMulet 2.1:

  • Reducing memory usage by changing data structure of polynomials

17.02.2021 AMulet 2.1:

  • Instead of PAC and NSS we now support LPAC on different abstraction levels See https://github.com/d-kfmnn/pacheck2 for a corresponding proof checker.

  • Optimized polynomial generation
