The ONFI 4.1 library provides the combo driver / receiver cells, the
ODT / driver impedance calibration cell, and the voltage reference
cell to support both single-ended and differential ONFI 4.1 signaling.
This library also meets the requirements for ONFI 3.0 & Toggle 2.0
signaling. The pad set includes a full complement of power, spacer,
and adapter cells to assemble a complete pad ring by abutment. An
included rail splitter allows isolated ONFI domains to be placed in
the same pad ring with other power domains while maintaining
continuous VDD/VSS in the pad ring for robust ESD protection. Ported from our TSMC 16 silicon proven design.
