Abstract
Designer's Workbench (DWB) increases the productivity of the design-aids user by buffering the user from the idiosyncrasies of the application programs and the computers on which they run. These aids are used during the electrical design, physical design, and test development of both custom electronics and printed wiring boards. The design-aids programs were left unchanged on their original computers and are accessed via an interlocation computing network using the capabilities of the PWB/UNIX <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∗</sup> operating system. All job control, file management, and data translation required for the programs are provided automatically. In addition to describing the design constraints applied during the development of DWB, this paper also introduces the three other papers in this issue that describe in detail the user, programmer, and production environments created by DWB.
