We present a method for exploiting symmetry-breaking constraints in modular schemes for constructing equivalent Boolean encodings of cardinality constraints. These techniques result in speedup in automated debugging of complex VLIW processors in formal verification by Correspondence Checking and efficient translation to Boolean Satisfiability (SAT).
We study the efficient formal verification of polymorphic heterogeneous multi-core architectures, such as Bahurupi, and also present insights on how to design such architectures at a high level of abstraction in order to facilitates their formal verification. To the best of our knowledge, this is the first work on formal verification of such architectures.
We present highly automatic techniques for formal verification of pipelined microprocessors with hardware support for multithreading. The processors are modeled at a high level of abstraction, using a subset of Verilog, in a way that allows us to exploit the property of Positive Equality that results in significant simplifications of the solution space, and orders of magnitude speedup relative to...
We present a method for automatic formal verification of Digital Signal Processors (DSPs) that have VLIW architecture and reconfigurable functional units optimized for accelerating Software Defined Radio (SDR) applications to be used for future space communications by NASA. The formal verification was done with the highly automatic method of Correspondence Checking by exploiting the property of Positive...
