A generator for high-density macrocells with hierarchical structure
K. Takeya, Mitsuyoshi Nagatani, S. Horiguchi · 1989
A parameterizable generator that can generate macrocells with multilevel hierarchies is described. High-density macrocells that incorporate random logic can be laid out automatically. The system generates full-custom macrocell layouts, sea-of-gates masterslice layouts, standard cell descriptions for such macrocells, and equivalent logic and function models for chip-level simulations
