Press Release - Date : July 18, 2006

Optunis releases System Maximizer 1.1.1. System Maximizer is used by scientists, engineers, and mathematicians to explore Digital Signal Processing algorithms. It combines a high level block diagram editor, a high speed system simulator, and signal processing analysis displays.

The Block Diagram Editor includes an extensive library of parameterizable elements. You simply drag and drop an element from the library to add it to your design. You may easily connect the blocks to each other, and when you've connected them, they stay connected thanks to rubber banding. You can choose to display parameters or a symbolic graphic for each individual element - so important details are never hidden. The extensive library of elements includes sources, sinks, arithmetic, and complex signal processing elements. In addition, you may make your own custom user elements, and custom user libraries.

System Maximizer incorporates a high speed a discrete time system level simulator. After simulating, you can choose to send the output to a text-file or view the simulation results within the System Maximizer signal viewers. The signal viewers include time plots, spectral plots, X-Y plots. Each viewer includes zooming capabilities, as well as cursors for taking measurements, and if you want to see the actual numbers, there is a paper tape view available.

Version 1.1.1 provides the following enhancements and bug fixes :

• Support for multi-rate systems
• New plotting functions and enhancements to existing plotting functions
• Improved group selection and drag & drop support

Changing the sample rate is easy in System Maximizer. To decrease the sample rate for a component, simply select it and set the skip_rate parameter to be how much slower your want it to run. To make components run faster, run the entire simulation at the higher rate, and decrease the sample rate for the slower component.

New plotting functions were added to the 1.1.1 release, to support polar plots, as well as constellation plots. The XY plotting was enhanced with a trace intensity slider to better show how often the paths are utilized. Several minor enhancements were provided to the time and frequency plots.

Optunis includes a 16-QAM hierarchical reference design with System Maximizer 1.1.1 which demonstrates the the new multi-rate features and displays constellation plots. The reference design takes binary data, transforms it into a square 16-QAM (Quadrature Amplitude Modulation) constellation, spectrally shapes it with a FIR (finite impulse response) filter, and up-converts the signal onto a desired carrier frequency using an NCO (numerically controlled oscillator). The design is instrumented with constellation plots, dual time plots, and spectrum plots to analyze and adjust the quality of the signal.

System Maximizer takes advantage of the latest hardware available from Apple and Intel with the Universal Binary format, as well as supporting PowerPC architectures.
