Paragon - A Behavioral Modeling Tool for Electronic Circuits and Systems


Technology # 04-13

Invention/Software Models the behavior of non-linear analog electrical circuits and systems

Fundamentally, it is a necessity to simulate the operation of electronic circuits on a computer BEFORE committing designs to expensive fabrication and production manufacturing. In order to accomplish this task, the simulator requires models of the electronic components. Many of these models are built in to the simulators or come in accompanying libraries for elementary electronic components such as transistors, diodes and passive elements. However, as design complexities have increased over the past decade, simulators can no longer handle the simulations required of an entire chip-level design at this low-level of abstraction -at least not in a time frame attractive to the designer.



Models the behavior of non-linear analog electrical circuits and systems



PARAGON is a software tool developed specifically to solve the problem of design complexities and enables this modeling to occur in a single day rather than weeks to months by facilitating model development and creation and validation. Recently, students at NC State University implemented a standard transistor model into a simulator and it took 7 weeks on average per team. A single student at the UA implemented the same model in PARAGON in 1week. This is indicative of the improvements and with experience this time can be reduced more significantly.



Models are entered using GUls that enable the user to input the model structure and equations. This information is stored in XML and then analyzed for efficient code generation in a number of hardware description languages the executable format for many modem-day simulators. Furthermore, these HDLs can be read into the tool and written out in other language(s) so that existing models can be migrated to other tools.


A final unique capability is a tool (Ascend) that is embedded within Paragon for automatically abstracting Behavioral models from the circuit level netlist descriptions. This automatic model order reduction software is unique.
