Software tools for concurrent design of electronic systems-benchmarking of various finite elements and volume analysis packages

Selecting analysis software can be a daunting task. Over the years, analysis tools have evolved from being off-line evaluation and study tools to a mainstream design and development necessity for concurrent design. These software tools are now a compelling requirement for a fiercely competitive environment with a reduced product development cycle time. Current solvers are complex algorithms that often require extensive research time to comprehend and consume precious time to understand. In this complex environment, the educated customer is clearly in the best position to take the challenge. This paper outlines industry tested proven techniques and processes to guide the reader through the difficult selection process to ensure optimum selection. A step-by-step approach is shown to identify and document specific user needs and establish a foundation for the selection and decision process. A simplified approach to understanding solver routines is also discussed. Details include a fundamentals review, without dissertation, of the various solver techniques from finite element to finite volume, and their respective merits. This paper is geared to assist users in selection of the best analysis tool for their needs. Correct benchmarking techniques are the kernel of this process and they are discussed carefully to assist and ensure correct software selection for the needs at hand.
