AIGER is a format, library and set of utilities for And-Inverter Graphs (AIGs). For up-to-date version and more information see 'http://fmv.jku.at/aiger'. To builb use './configure.sh && make'. The focus is on conversion utilities and a generic reader and writer API. A simple AIG library 'SimpAIG' is also included. It is currently only used in unrolling sequential models in 'aigunroll'. documentation: README this file FORMAT detailed description of the format LICENSE license and copyright libraries: aiger.h API of AIGER library ('aiger.c') aiger.c read and write AIGs in AIGER format simpaig.h API of SimpAIG library ('simpaig.c') simpaig.c A compact and simple AIG library (independent from 'aiger.c') examples: examples/*.aig simple examples discussed in 'FORMAT' examples/*.aag (same in ASCII format) examples/read.c decoder code for binary integer repr. examples/write.c encoder code for binary integer repr. examples/poormanaigtocnf.c simple applications reading the binary format examples/JaigerToCNF.java without use of the AIGER library (prototypes for competition readers) utilities: aigand conjunction of all outputs aigbmc new bounded model checker for format 1.9.x including liveness aigdd delta debugger for AIGs in AIGER format aigdep determine inputs on which the outputs depend aigflip flip/negate all outputs aigfuzz fuzzer for AIGS in AIGER format aiginfo show comments of AIG aigjoin join AIGs over common inputs aigmiter generate miter of AIGER models aigmove treat non-primary outputs as primary outputs aignm show symbol table of AIG aigor disjunction of all outputs aigreset normalize constant reset either to 0 or 1 aigsim simulate AIG from stimulus or randomly aigsplit split outputs into separate files aigstrip strip simbols from AIG aigtoaig converts AIG formats (ascii, binary, stripped, compressed) aigtocnf translate combinational AIG into a CNF aigtoblif translate AIG into BLIF aigtodot visualizer for AIGs using 'dot' format aigtosmv translate sequential AIG to SMV format andtoaig translate file of AND gates into AIG aigunroll time frame expansion for bmc (previously called 'aigbmc') bliftoaig translate flat BLIF model into AIG mc.sh SAT based model checker for AIGER using these tools smvtoaig translate flat boolean encoded SMV model into AIG soltostim extract input vector from DIMACS solution wrapstim sequential stimulus from expanded combinational stimulus Armin Biere, JKU, Mai 2014.
