What I/O standard is used by the FPGA core logic? - What I/O standard is used by the FPGA core logic? Description The FPGA core logic uses single ended signals relative to the core power supply. For example, differential signals are resolved to single ended signals in the I/O buffer and propagate out as single ended signals.
