Method for constructing an integrated circuit device having fixed and programmable logic portions and programmable logic architecture for use therewith

A method of creating an integrated circuit device for performing a set of functions, said method comprising:

• partitioning said set of functions into (a) a first group of functions to be performed by fixed logic, and (b) a second group of functions to be performed by programmable logic;
• obtaining a hardware description language representation of fixed logic for performing said first group of functions;
• obtaining a hardware description language representation of said programmable logic based on a programmable logic architecture, said programmable logic architecture being optimized for at least one of (a) description by a hardware description language, and (b) fabrication in portions among portions of fixed logic;
• merging said hardware description language representation of said fixed logic for performing said first group of functions and said hardware description language representation of said programmable logic to create a unified hardware description language representation of said integrated circuit device.
