This paper describes a basic electronics learning system combining a hypermedia system explaining theoretical concepts with a basic simulator and a virtual laboratory to improve the engineering education process on electronics and the students skills before going to the actual laboratory. To accomplish this objective the system also provides a set of complementary resources, constituting a brid...

We present a method of automatically generating circuit designs using evolutionary search and a set of circuit-constructing primitives arranged in a linear sequence. This representation has the desirable property that virtually all sets of circuit-constructing primitives result in valid circuit graphs. While this representation excludes certain circuit topologies, it is capable of generating a ...

As the component parameters of analog circuits are influenced by tolerance, a soft fault-concept diagnosis model in this paper, which is based on the qualitative concepts of cloud model theory, is proposed to achieve the complete description of fault states and the fast diagnosis. The diagnosis model uses the cloud transform method to represent the conceptual soft classification of the multiple...

This contribution proposes a synchronization technique for solvers able to handle analogue extensions to SystemC, for modelling of general, mixed-mode systems with digital and non-linear analogue behaviour. In order to comply with the SystemC simulation cycle semantics, we link the analogue kernel to the SystemC environment as a user module and synchronize it with the SystemC kernel via a locks...

An approach to integrated mixed-mode simulation is described in which the popular SPICE circuit simulator is extended to analyze digital circuits at the gate, functional or behavioral levels. The analogue-to-digital conversion is provided by (multilevel) parameterized “thresholders” which assign digital signals to subranges of voltages determined by a set of voltage thresholds. The digitalto-an...

Analogue simulation is a novel mode of scientific inference found increasingly within modern physics, and yet all but neglected in the philosophical literature. Experiments conducted upon a table-top ‘source system’ are taken to provide insight into features of an inaccessible ‘target system’, based upon a syntactic isomorphism between the relevant modelling frameworks. An important example is ...
