ABSTRACT:
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 re-synthesis 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 re-synthesis) in either direction between FPGA and ASIC designs.
