Enable D4 Fine Delay (DQS Delay Chain) logic option

A logic option that turns on fine delay resolution for the D4 delay cell. This is an advanced option; use this option only after compiling your project, checking I/O timing, and determining that timing is unsatisfactory. This option is ignored if it is applied to anything other than an input or bidirectional pin.

This option is available for all Intel devices supported by the Intel^® Quartus^® Prime software.
