WEVA Optimization Toolbox
The WEVA Optimization Toolbox is a powerfull tool in development process of behaviour
models in different physical levels. The user can implement his model ideas direct in
source code or can use a hardware description language and use a simulator of his choice
to evaluate the model. WEVA is managing the parameter extraction process in using one
of 5 very sophistcated optimization algorithm. This fitting process is based direct of
measurement or simulated data. After that the results of the model - measurement compare
can visualize and documented. The program can be used on Windows NT/98, Sun Solaris and
Linux in a same manner.
- Successfully in use since 4 Years at Robert Bosch GmbH Central Research.
- Development and Parametrization of behaviour models.
- Mixed electrical and non-electrical system simulation.
- Based on measurement data.
- GUI based entry.
- Control of different simulators, miscellaneous Optimization algorithm and data visualization.
The following list gives a small impression about the application areas of WEVA:
- Circuit optimization:
- Design centering
- Amplifier design
- Filter design
