CADBIT II - Computer-Aided Design for Built-In Test. Volume 2
Abstract
The objective of CADBIT II was to develop a CAD workstation-based system with software to help designers incorporate Built-In Test (BIT) in their CAD-based circuit board designs. The CADBIT II system consists of a Unix-based workstation, electronic CAD software, and the contractor-developed CADBIT II software module. CADBIT II benefits printed circuit board designers through four major functions. The Tutorial function increases awareness and understanding of Built-In Test techniques. This function offers on-line access to an extensive database of information on current techniques used to implement built-in test in digital, analog, and hybrid (mixed digital and analog) circuit boards. The Selection function helps designers choose the best technique for their design. The selection log compares characteristics and attributes of each BIT technique in the CADBIT database to information about the user's specific 'Circuit Under Test'. The CAD Insertion function helps designers implement a selected BIT technique in a CAD schematic. This function provides a Default Design: with a consistent set of components to implement the selected BIT technique. The Evaluation function analyzes the design impact of adding Built-In-Test circuitry based on total board area, weight, and power 'penalties' for each BIT.
