OEA International Announces Enhancements to Spiral Inductor Design and Synthesis Tool

Morgan Hill, California - June 1, 2005. OEA International, Inc. announces new update to its popular SPIRAL™, a 3D inductor design toolset for designing and synthesizing on-chip inductors in analog and RF chips. The new version of SPIRAL adds:

1. A set of RF design engineering tools for doing common calculations in RF passive circuits. These include basic resistance and inductance series/parallel calculations and conversions, transmission lines on PCBs, wavelength calculations, resonance circuits and impedance matching circuit calculations.

2. A new circuit simulation environment for quickly simulating the newly designed inductors into user definer RF spice circuits, such as tank circuits. The circuits are simulated with the fast OEA PANTHER linear spice simulator and the resultant S, Y, Z-Parameter and LRQ files are displayed on the PlotView interface.

3. New solving algorithms for faster and more accurate substrate models, capacitance models, and RL skin effect models.

While SPIRAL simulation was already the number one choice for advanced inductor design, these enhancements demonstrate OEA's commitment to delivering the most powerful and fastest design tools for the most difficult and specialized applications.

SPIRAL Tool Overview
By providing a simple set of performance and physical specifications SPIRAL allows designers to automatically and quickly synthesize, analyze, and optimize a wide range of inductors, including baluns, differential inductors and transformers. In a matter of minutes SPIRAL can find and synthesize an inductor optimally suited to the users' specific circuit requirements. SPIRAL can be used in a batch mode, in an interactive mode through a robust graphical users interface, or seamlessly from within the Cadence DFII environment SPIRAL generates all of the user modeling needs including GDS2 layout; S-Parameters; Y-Parameters; Z-Parameters; plots of inductance, resistance and quality factor versus frequency; and narrow-band and wide-band compact spice models. SPIRAL results have proven to be highly accurate for mainstream and advanced process proven through validation.

Pricing and Availability
Spiral is available immediately on Linux and Solaris based systems starting at $25,000 for a time-based license.

About OEA International
OEA International, Inc. was formed in 1988 to address demanding IC extraction problems. The company has secured the extraction accuracy leadership role by working closely with major IC and system companies using the most modern process technologies available. Through these relationships, the company has applied it 3D extraction expertise to provide a family of critical net design tools, signal integrity analysis tools, and RF component design tools.

RF/analog designers also have available RF-PASS™, a passive component analysis tool which ensures the most accurate models for on-chip resistors, capacitors, coil transformers and wind up/down inductors. For additional information call (408) 778-6747, or visit OEA online at http://www.oea.com.
