A new scheme of Schottky FPGA (SFPGA) IC solution is proposed. The
chip is organized by embedded analog, memory, and logic units with on
chip apparatus and
software means to partitioning, altering selected portions of hardware. The process means is based on the combined Schottky
CMOS (SCMOS, U.S. Pat. No. 6,590,800) and Flash technology. The circuit means is based on SCMOS-DTL gate arrays.
Software means is based on the C++ procedures with levels of LUT. The SFPGA device supports GHz low power ASIC mixed
signal product applications with embedded analog, logic, and
memory array units. Several
multiplexing schemes are disclosed, which accommodate tasks to vary the Vt and
transmission line transmission of selected
transistor or IO nets, and therefore their analog and
digital device properties. A
voltage doubler and supply booster and a Digital-Analog-Digital-Translator (DADT) apparatus are also disclosed in accordance with the present invention. Accordingly, the present invention includes control schemes to field program basic circuit element or any critical nets, and to alter the functionality of certain predetermined circuit units, and update array interconnections, accessing stored protocols, algorithms in all chips in the embodiment subsystem of a SFPGA
chip sets.
