VLSI Design Language Standardization Effort in Japan

This paper presents a new standard for a hardware design language (UDL/I: Unified Design Language for Integrated Circuit) that is being developed in Japan for application to logic synthesis technology. The features of UDL/I are as follows. It (1) is a logic synthesis oriented design language, (2) provides a formal and strict semantic definitions, (3) supports high-level constructs for easy hardware description, and (4) supports quick and error free design.
