To enable formal reasoning in one of the most commonly used description language VHDL, we define a formal model of the VHDL language in Isabelle/HOL.

Generating Witness of Non-Bisimilarity for the pi-Calculus

1 code implementation31 May 2017 Ki Yung Ahn, Ross Horne, Alwen Tiu

In the logic programming paradigm, it is difficult to develop an elegant solution for generating distinguishing formulae that witness the failure of open-bisimilarity between two pi-calculus processes; this was unexpected because the semantics of the pi-calculus and open bisimulation have already been elegantly specified in higher-order logic programming systems.
