This is the 11th competitive event for hardware model checkers.
As introduced last year we will have a word-level track based on the BTOR2 format, which is described in our CAV'18 paper. The Btor2Tools tool suite provides a generic parser Btor2Parser and a simulator BtorSIM, which are useful for parsing and random simulation of BTOR2 models, as well as for witness checking. There is also a simple bounded model checker BtorMC, distributed as part of Boolector.
Depending on the interest of the community we also consider to run a single safety property track using the AIGER format as in earlier competitions until 2017. Alternatively model checkers only supporting the AIGER format can run on bit-blasted word-level models.
The hardware setup is identical to the last competitions. It is running on our Ubuntu 18.04.3 LTS 64 bit cluster with two Intel(R) Xeon(R) CPU E5-2620 v4 @ 2.10GHz CPUs and 128 GB of main memory on each node.
Each solver has full access to both processors on one node, thus combined 16 cores (32 virtual cores) and 128 GB of main memory. Accordingly a memory limit of 120GB will be enforced. As in the previous competition in 2017 we will further use a time limit of 1 hour of wall clock-time.
