Inputs and outputs for embedded field programmable gate array cores in application specific integrated circuits

摘要

An architecture to efficiently handle primary input and output signals for an embedded FPGA core in an ASIC is disclosed. Only the FPGA core is used without wire-bonding pads and pad ring found in conventional embedded FPGAs. The input and outputs of the embedded FPGA core can be made peripherally or at selected locations throughout the core to obtain high I/O-to-logic ratios and flexibility in I/O placement with high routability.
