DASLL: An Automatic Printed Circuit Board Layout System

摘要

DASLL stands for Design Automation System at Lawrence Livermore and is a system of computer programs to automatically lay out printed circuit boards. The focus has been on two-sided PCB fabrication aids; primarily drill tape, documentation, and artwork generation (including etch, silkscreen, and drill schedule artwork). Limited four-layer PCBs are also possible with the program. DASLL can be used in either batch-interactive or batch made of operation by technicians, draftsmen, designers, or engineers. Flexibility in being able to accomodate a diversity of trimline geometries and component shapes and placements was a goal in the design of the software. The system is also very flexible in its capability to deal with physical design rules. A principal objective for the system has been low-volume, quick turnaround response for low and medium density custom printed circuit boards. (ERA citation 05:032705)
