CFI Design Representation Information Modeling Experiences Laurence C. Brevard CFI 1.0 Design Representation TSC Chair Member of the EDIF Technical Committee MCC 3500 West Balcones Center Drive Austin, Texas 78759 laurence@brevardandbrevard.com ABSTRACT CFI is defining standardized interfaces to the common services of CAD Frameworks in order to reduce the cost of integration of design tools. As part of that effort, CFI's Design Representation Technical Sub-committee (DR TSC) is defining a programming interface (PI) to electronic design data. The DR TSC has found that information modeling is a necessary mechanism for finding agreement on the types of data found in CAD systems. That agreement is essential to providing standardized access.
