Abstract

MADMACS is an interactive graphics editor for hierarchical VLSI layouts. Like most editors, it includes all editing facilities needed for complex circuit design. However, Madmacs provides a powerful user interface to facilitate and speedup regular and structured layout editing. This technique, similar to the macro editing concept used in the EMACS text editor is called ALP: Automated Layout Procedure. It permits the easy update of a design when only some slight modifications are required. In this paper, we describe the general features of Madmacs and our first experiences with a preliminary implementation.
