Abstract :
This paper describes Layla, a Pascal-based hardware description language for the specification of VLSI layouts. The primary application of Layla is the development of parameterized cell libraries. Important features include Pascal´s computational power and file I/O facilities, hierarchical (cell-based) layout generation, a run-time design parameter file, an extendible layer set, external compilation, the ability to support different output formats, and the automatic generation of parameterized Layla from artwork.
