Where can I get package RLC values for Cyclone IV E devices in the 484-pin UBGA package?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

The RLC values for the 484-Pin Ultra FineLine Ball-Grid Array (UBGA) package of Cyclone® IV E devices (package code U19) are not available in cyclone4 rlc.xls on the IBIS Models home page.  The  Quartus®  Prime software doesn\'t support generation of IBIS models with the RLC values for the package either. 

Resolution

The RLC values for the Cyclone IV E devices in the 484-pin UBGA package can be found below :
