APPLICATION-SPECIFIC INTEGRATED CIRCUIT EQUIVALENT OF PROGRAMMABLE LOGIC AND ASSOCIATED METHOD

摘要

PROBLEM TO BE SOLVED: To provide an ASIC equivalent of an FPGA more efficiently and economically.

SOLUTION: Providing ASIC equivalents of FPGAs is facilitated and made more efficient and economical by using an ASIC architecture including a plurality of so-called hybrid logic elements (HLEs), each of which can provide a portion of the full functionality of an FPGA logic element (LE). The functionality of each FPGA LE implementing a user's logic design can be mapped to one or more HLEs without resynthesis of the user's logic. Only as many HLEs as are necessary are used to perform the functions of each LE. The one-for-one equivalence between each LE and either (1) one HLE or (2) a group of HLEs facilitates mapping (without resynthesis) in any direction between FPGA and ASIC designs.
