Obtain the latest version of Minisat at https://github.com/niklasso/minisat Unpack it into ic3ref/minisat (so that Solver.h is at ic3ref/minisat/minisat/core/Solver.h). Make. 2. Obtain the AIGER utilities (aiger-1.9.4.tar.gz) at http://fmv.jku.at/aiger/ Unpack it into ic3/aiger (so that aiger.c is at ic3ref/aiger/aiger.c). DO NOT MAKE. 3. At ic3ref, make. 4. Run ./IC3 [<option>|<property ID>]* < <AIGER file> where -v: enables verbose output -s: enables output of runtime statistics -r: randomizes execution to better indicate performance -b: uses basic generalization <property ID>: an integer specifying a property index in the AIGER file, which defaults to 0. If 'B' is non-0, prefers 'B' to 'O' (see AIGER 1.9 format). <AIGER file>: AIGER formatted file with .aig or .aag extension
Issues (1) and (2) are quick to fix, although I'm not currently maintaining the code.
Issues (3) and (4) are somewhat fundamental to the implementation.
Despite the compilation process succeeding without any issues, running the command ./IC3 with the specified parameters produces nothing. The process must be killed in order to exit. I traced down the bug to this line in aiger.c: aiger_read_header
aiger_next_ch (reader);
if (reader->ch != 'a')
return aiger_error_u (private,
"line %u: expected 'a' as first character",
reader->lineno);
The aiger files being run were the benchmarks that were run in the original IC3 paper. It seems that the aiger files are not being read/parsed properly, despite providing proper ones.
Hi, again:) The following `corner-case' file causes IC3 to crash with segfault:
