# WARNING: When updating to a newer snapshot, because upstream doesn't do
# shared library versioning, run abipkgdiff (from libabigail) against the
# old and new binary and debuginfo packages to detect abi changes that would
# require bumping the shared library version, e.g.,
#   abipkgdiff --d1 abc-libs-debuginfo-<old>.rpm \
#              --d1 abc-debuginfo-<old>.rpm \
#              --d2 abc-libs-debuginfo-<new>.rpm \
#              --d2 abc-debuginfo-<new>.rpm \
#              --devel1 abc-devel-<old>.rpm \
#              --devel2 abc-devel-<new>.rpm \
#              abc-libs-<old>.rpm abc-libs-<new>.rpm
# If the shared library version is bumped, remember to rebuild dependent
# packages, finding them using e.g.
#   repoquery --whatrequires abc-libs
# This should be done for each branch in which abc-libs will be updated.

%description
ABC is a growing software system for synthesis and verification of
binary sequential logic circuits appearing in synchronous hardware
designs.  ABC combines scalable logic optimization based on And-Inverter
Graphs (AIGs), optimal-delay DAG-based technology mapping for look-up
tables and standard cells, and innovative algorithms for sequential
synthesis and verification.

ABC provides an experimental implementation of these algorithms and a
programming environment for building similar applications.  Future
development will focus on improving the algorithms and making most of
the packages stand-alone.  This will allow the user to customize ABC for
their needs as if it were a toolbox rather than a complete tool.
