PVS stands for "Prototype Verification System." It consists of a specification language integrated with support tools and a theorem prover. PVS tries to provide the mechanization needed to apply formal methods both rigorously and productively. This tutorial serves to introduce PVS and its use in the context of hardware verification. In the first section, we briefly sketch the purposes for which PVS is intended and the rationale behind its design, mention some of the uses that we and others are making of it. We give an overview of the PVS specification language and proof checker. The PVS language, system, and theorem prover each have their own reference manuals, which you will need to study in order to make productive use of the system. A pocket reference card, summarizing all the features of the PVS language, system, and prover is also available. The purpose of this tutorial is not to describe in detail the features of PVS and how to use the system. Rather, its purpose is to...
Experiments with ZF Set Theory in HOL and Isabelle
 IN PROCEEDINGS OF THE 8TH INTERNATIONAL WORKSHOP ON HIGHER ORDER LOGIC THEOREM PROVING AND ITS APPLICATIONS, LNCS

"... Most general purpose proof assistants support versions of typed higher order logic. Experience has shown that these logics are capable of representing most of the mathematical models needed in Computer Science.

Most general purpose proof assistants support versions of typed higher order logic. Experience has shown that these logics are capable of representing most of the mathematical models needed in Computer Science. However, perhaps there exist applications where ZFstyle set theory is more natural, or even necessary. Examples may include Scott's classical inverselimit construction of a model of the untyped  calculus (D1 ) and the semantics of parts of the Z specification notation. This paper
Merging HOL with Set Theory  preliminary experiments
, 1994
"... Set theory is the standard foundation for mathematics, but the majority of general purpose mechanised proof assistants support versions of type theory (higher order logic). Examples include Alf, Automath, Coq, EHDM, HOL, IMPS, LAMBDA, LEGO, Nuprl, PVS and Veritas. For many applications type theory w ..."

Set theory is the standard foundation for mathematics, but the majority of general purpose mechanised proof assistants support versions of type theory (higher order logic). Examples include Alf, Automath, Coq, EHDM, HOL, IMPS, LAMBDA, LEGO, Nuprl, PVS and Veritas. For many applications type theory works well and provides, for specification, the benefits of typechecking that are wellknown in programming. However, there are areas where types get in the way or seem unmotivated. Furthermore, most people with a scientific or engineering background already know set theory, whereas type theory may appear inaccessable and so be an obstacle to the uptake of proof assistants based on it. This paper describes some experiments (using HOL) in combining set theory and type theory; the aim is to get the best of both worlds in a single system. Three approaches have been tried, all based on an axiomatically specified type V of ZFlike sets: (i) HOL is used without any additions besides V; (ii) an emb...
Set Theory, Higher Order Logic or Both?

The majority of general purpose mechanised proof assistants support versions of typed higher order logic, even though set theory is the standard foundation for mathematics. For many applications higher order logic works well and provides, for specification, the benefits of typechecking that are wellknown in programming. However, there are areas where types get in the way or seem unmotivated. Furthermore, most people with a scientific or engineering background already know set theory, but not higher order logic. This paper discusses some approaches to getting the best of both worlds: the expressiveness and standardness of set theory with the efficient treatment of functions provided by typed higher order logic.
