Clock MUX Protection logic option

A logic option that causes multiplexers in a clock network to be decomposed and mapped to two-to-one MUX trees. This option is useful for allowing the TimeQuest Timing Analyzer to understand clock behavior.

Note:

A clock multiplexer can cause glitches.

This option is a project-wide option. This option is available for all Altera devices supported by the Quartus® Prime Standard Edition software except MAX3000 and MAX7000 devices.
