SYSTEM FOR CREATING LAYOUT PATTERN FOR MANUFACTURING MASK ROM, MASK ROM MANUFACTURED USING THE SYSTEM, AND METHOD FOR CREATING MASK PATTERN

摘要

When generating a temporary ROM code file and a design information file, a host server generates a dedicated ROM compiler and an intermediate file associated with the dedicated ROM compiler. In a workstation, the dedicated ROM compiler is executed, whereby the contents of a design information file are changed to the contents corresponding to a correct ROM code. The dedicated ROM compiler is specifically designed to be capable of changing only a particular design parameter and the design information file associated with the temporary ROM code file.
