Algorithmic verification of asynchronous programs

Verification of Asynchronous Programs with Nested Locks

In this paper, we consider asynchronous programs consisting of multiple threads running in parallel. Each of the thread is equipped with a multi-set. The threads can create tasks and post them onto multi-sets of other threads or read a task from their own. In addition, they can synchronise through a finite set of locks. In this paper, we show that the reachability problem of such class of async...

Algorithmic Verification of Single-Pass List Processing Programs

We introduce streaming data string transducers that map input data strings to output data strings in a single left-to-right pass in linear time. Data strings are (unbounded) sequences of data values, tagged with symbols from a finite set, over a potentially infinite data domain that supports only the operations of equality and ordering. The transducer uses a finite set of states, a finite set o...

Verification of asynchronous circuits

The purpose of this thesis is to introduce proposition-oriented behaviours and apply them to the verification of asynchronous circuits. The major contribution of propositionoriented behaviours is their ability to extend existing formal notations to permit the explicit use of both signal levels and transitions. This thesis begins with the formalisation of proposition-oriented behaviours in the c...
