ID:21166 Pins "<name>" and "<name>" have pseudo differential I/O standard, but are fed by a differential buffer. The Fitter automatically splits this differential buffer into a pseudo-differential atom driving 2 single-ended output buffers, which in turn drive the pseudo-differential output pins.
CAUSE: The Fitter reports that a differential output pin pair with pseudo-differential I/O standard is being driven by a differential output buffer.
ACTION: No action is required. To avoid receiving this message, use two single-ended buffers to drive the differential pin pair.
