How do I select a data width of 16bits for the DDR3 SDRAM UniPHY IP in the Cyclone V EPE IP tab?

Description

The Cyclone® V EPE IP tab is missing the 16-bit data width option for the DDR3 SDRAM UniPHY IP.

Workaround/Fix

Select 32-bit and modify the instantiation in the I/O tab manually (i.e adjust pin counts - # dq pin, #dqs pins ) to create a 16-bit instantiation. Reuse the entries from the 32-bit option for the CLK, PLL, RAM, and Logic tabs to estimate 16-bit power.
