UDL/I standardization effort another approach to HDL standard
Osamu Karatsu · 1991
UDL/I (Unified Design Language for Integrated circuits) is a hardware design language (HDL) for VLSI design. It was developed in Japan by a standardization committee that consists of over 30 companies, universities and related organizations. One-third of the members are non-Japanese. UDL/I is a logic synthesis oriented design language that (1) provides a formal and strict semantic definition, (2) supports a high level construct for a case in hardware description, and (3) allows quick and error-free design. The committee completed the language reference manual for the first version in 1990 and will provide typical UDL/I processors (i.e. a compiler, a simulator and so on) for trial runs by the end of March, 1992. A standardized HDL will contribute to the area of high level design and will coexist in the CAD environment with VHDL to cover the different aspects of hardware design activity.>
