In computer science, an abstract state machine (ASM) is a state machine operating on states that are arbitrary data structures (structure in the sense of mathematical logic, that is a nonempty set together with a number of functions and relations over the set).
This abstract machine over-approximates the behaviours of the system: the abstract system is thus made simpler to analyze, at the expense of incompleteness (not every property true of the original system is true of the abstract system). If properly done, though, abstract interpretation is sound (every property true of the abstract system can be ...
Abstract machines are typically categorized into two types based on the quantity of operations they can execute simultaneously at any given moment: deterministic abstract machines and non-deterministic abstract machines. [2] A deterministic abstract machine is a system in which a particular beginning state or condition always yields the same ...
Each level uses a system of expression involving a unique set of objects and compositions that apply only to a particular domain. [12] Each relatively abstract, "higher" level builds on a relatively concrete, "lower" level, which tends to provide an increasingly "granular" representation. For example, gates build on electronic circuits, binary ...
VisSim (now Altair Embed) uses a graphical data flow paradigm to implement dynamic systems, based on differential equations. Version 8 adds interactive UML OMG 2 compliant state chart graphs that are placed in VisSim diagrams, which allows the modelling of state based systems such as startup sequencing of process plants or serial protocol decoding.

OMG focuses Model Driven Architecture® on forward engineering, i.e. producing code from abstract, human-elaborated modeling diagrams (e.g. class diagrams) [citation needed]. OMG's ADTF (Analysis and Design Task Force) group leads this effort. With some humour, the group chose ADM (MDA backwards) to name the study of reverse engineering.
The split between analysis and design models: The analysis domain expresses precisely what the system must do, the design domain is a model of how the Shlaer–Mellor virtual machine operates for a particular hardware and software platform. These models are disjoint, the only connection being the notation used to express the models.
