Qualitative Circuit Models for ECAD Analysis and Support Tools
نویسنده
چکیده
In ECAD application areas there is a real need for electrical circuit modelling and analy sis tools at an intermediate level between analogue and state based simulators Numerical tools do not capture the abstractions valued by engineers and logical functional models do not maintain su cient a nities with the electrical properties of a system This paper examines the nature of this problem and then describes MCIRQ a qualitative modelling tech nique that o ers a solution We believe qualitative and quantitative methods can be combined to gain considerable bene ts in future integrated ECAD en vironments

Qualitative Modelling of Linear Networks in EGAD Applications
There is a real need for qualitative circuit analysis tools in the ECAD application area . Recent simulators based on finite many valued resistance and current models (switch-level models) have been shown to have serious limitations. Through independent parallel research the QR community has produced qualitative electrical models and simulators that have been successfully used in software tools...
متن کاملLayout Data in Tcad Frameworks
Today Technology CAD (TCAD) tools are essential to the development of modern Integrated Circuit (IC) fabrication processes. They are as well, required in the design/ optimization of very detailed and critical circuits related to a given IC process, where the usual higher level tools in Electronic Design CAD (ECAD) frameworks do not exhibit the precision or the features required. The boundary be...
متن کاملA Qualitative Assessment of the Evidence Utilization for Health Policy-Making on the Basis of SUPPORT Tools in a Developing Country
Background SUPPORT tools consist of 18 articles addressing the health policy-makers so that they can learn how to make evidence-informed health policies. These tools have been particularly recommended for developing countries. The present study tries to explain the process of evidence utilization for developing policy documents in the Iranian Ministry of Health and Medical Education (MoHME) and...
متن کاملQualitative Modelling of Linear Networks in Engineering Applications
There is a real need for electrical circuit modelling and analysis tools at an intermediate level between analogue and statebased simulators. Numerical tools do not capture the abstractions valued by engineers and logical/functional models do not maintain sufficient affinities with the electrical properties in a system. Qualitative models have had some notable successes in filling this gap but ...
متن کاملSca Method Based on Qualitative Simulation
It is an effective method to use qualitative reasoning theory to realize sneak circuit analysis (SCA). The method using qualitative modeling combined with functional simulation to realize sneak circuit analysis. The qualitative models of resistive element, switch, transistor, MOS pipe, digital devices, analog devices, mechanical devices and other types of components were established and the qua...
