Title: SILT: a VLSI design language
Author: Davis, Tom
Author: Clark, James
Date: October 1982
Abstract: SILT is an efficient, medium-level language to describe VLSI layout. Layout features are described in terms of a coordinate system based on the concept of relative geometry. SILT provides hierarchical cell description, a library format for parameterized cells with defaults for the parameters, constraint checking (but not enforcement), and some name control. It is designed to be used with a graphical interface, but can be used by itself.
