Generating VHDL-A - like models using ABSynth
نویسندگان
چکیده
A method for the graphical specification and the automatic generation of analogue behavioural models is presented. This method has been implemented as a new software tool called ABSynth. The behaviour of the component to model is described as a functional diagram, which is then automatically translated into a VHDL-A-like analogue hardware description language. No syntax knowledge is necessary and the modelling time is reduced.

Behavioral Modeling and Simulation of Semiconductor Devices and Circuits Using VHDL-AMS
During the past few years, a lot of work has been done on behavioral models and simulation tools. But a need for modeling strategy still remains. The VHDL-AMS language supports the description of analog electronic circuits using Ordinary Differential Algebraic Equations (ODAEs), in addition to its support for describing discrete-event systems. For VHDL-AMS to be useful to the analog design ...
متن کاملAutomatic Extraction of Behavioral Models from Simulations of Analog/mixed-signal (ams) Circuits
Verification of analog circuits is becoming a bottle-neck for the verification of complex analog/mixed-signal (AMS) circuits. In order to assist functional verification of complex AMS system-on-chips (SoCs), there is a need to represent the transistor-level circuits in the form of abstract models. The ability to represent the analog circuits as behavioral models is necessary, but not sufficient...
متن کاملGenerating VHDL Source Code from UML Models of Embedded Systems
Embedded systems’ complexity and amount of distinct functionalities have increased over the last years. To cope with such issues, the projects’ abstraction level is being continuously raised, and, in addition, new design techniques have also been used to shorten design time. In this context, Model-Driven Engineering approaches that use UML models are interesting options to design embedded syste...
متن کاملMonte Carlo Simulation Using VHDL-AMS
Monte Carlo simulation is widely used in Spice like circuit simulators. It allows to obtain statistical information derived from estimates of the random variability of circuit parameters. Multiple simulation runs are carried out with different sets of parameters. VHDL-AMS provides flexible possibilities to specify nominal and tolerance values and their distributions. Correlation between paramet...
متن کاملCompact Modeling of Emerging Technologies with VHDL-AMS
This paper deals with the compact modeling of several emerging technologies: first, the double-gate MOSFET (DG MOSFET), and second, the carbon nanotube field-effect transistor (CNTFET). For CNTFETs, we propose two compact models, the first one with a classical behavior (like MOSFET), and the second one with an ambipolar behavior (Schottky-barrier CNTFET). All the models have been compared with ...
