dasll (design automation system at lawrence livermore) is a set of computer programs for printed circuit board (pcb) layout. the dasll system can process a number of pcb trimlines, including: dec 1, 2, 4, and 6 high configurations, cli, augat, varian, and several rectangular geometries; others can be added. over 800 components and generic package types are available in daslldb, the system reference library. two-layer boards with non-gridded (structured) power and ground busses are supported, and pcb densities of approximately 1.2 square inches per equivalent ic (or less dense) are best accommodated by dasll. the system has been used to make etch artwork and drill tapes (starting with a schematic drawing) for a six ic cli board in less than two working days. initial processing will produce reports and computer printer-plots which can be used to verify the input final output can include silkscreen photo-artwork, pcb etch photo-artwork, punched paper tapes for the slo-syn and pratt-whitney n/c drill machines, and computer listings of signal strings, parts lists, etc...software description: cdc7600. lrltran. ltss. gerber photoplotter
