Abstract:
1. A design system comprising: an interactive design unit interactively receiving a circuit design and providing an integrated circuit (IC) design, said interactive design unit comprising: a layout unit receiving a circuit description of said IC design, said layout unit representing portions of said IC design in a grid and glyph format, wherein glyphs in said grid and glyph format include point glyphs, line glyphs and rectangle glyphs; a checking unit checking grid and glyph portions; an elaboration unit generating a target layout from each checked one of said grid and glyph portions; a data prep unit preparing said target layout for mask making; a pattern caching unit selectively substituting previously cached results for ones of said grid and glyph portions; a mask shape generation unit generating mask shapes from a prepared said target layout; a simulation unit generating wafer contours from generated said mask shapes; an extraction unit extracting circuit models from generated said wafer contours; and a modeling unit generating expected IC electrical parameters from said circuit models.
