Cameleon, a Process Tolerant Symbolic Layout System

CAMELEON is a symbolic layout system, suited for industrial designs, delivering layouts that can bear comparison with (orthogonal) manual layouts. The Technology Description Language (TDL), describing layout primitives and design rules, allows to customize the system to any technology. More complex primiltives, like S- or L-shaped transistors may be included in the stick diagram. Compaction is considered as a basic operation in the creation of stick diagrams: the designer can control compaction and receives feedback. An automatic technology conversion for all designed cells is obtained by modifying the TDL description. An electrical rules check is provided, and a fast circuit extraction module makes the link to simulation and verification tools.
