Gurevich's Abstract State Machines (ASM) constitute a high-level speciication language for a wide range of applications. The existing tool support for ASM|currently including type-checking, simulation and debugging|should be extended to support computer-aided veriication, in particular by model checking. In this paper we introduce an interface from our… (More)
Blindness (amaurosis) as a complication of cosmetic surgery is not common, but has been reported in cases of blepharoplasty, as well as in connection with facial injection of various substances, including collagen. The anatomic and pathophysiologic basis for embolization of the retinal artery is presented, and the literature regarding thromboembolic,… (More)
We present a design approach which allows us to formally specify a real–life processor as composed out of its basic architectural (formally specified) components. The methodology provides means to rely upon hierarchical refinements and modular structuring of the specifications as a discipline to control the behaviour of complex units in terms of the… (More)
This paper provides the rst step of a full mathematical description of the APE100 parallel architecture. The description consists of several models, at diierent levels of abstraction, corresponding to views of the architecture provided by diierent languages used within the APE100 compilation chain (a crucial part of the software environment of APE100). Here… (More)
As introduced in the Lipari guide, Abstract State Machines (abbreviated as ASMs) are untyped. This is useful for many purposes. However, typed languages have their own advantages. Types structure the data, type checking uncovers errors. Here we propose a typed version of ASMs.
Appropriate tool support is an essential factor for an eeec-tive application of formal methods to real-life speciication and modelling tasks. However, the current state of the art of tool support for Abstract State Machines is not considered very satisfactory by practitioners. After discussing some possible reasons for this, we report about the ASM… (More)
High level design decisions as HW/SW-partitioning and instrumenting of building blocks can be supported efficiently by detailed analysis of dynamic instruction usage. In many cases the instruction usage is specific to the application domain in view. We present a very fast analysis approach based on high level system models. Complex application… (More)
