Altera Quartus II Settings File - Manual (Page 257)

DEFAULT_HOLD_MULTICYCLE
Determines the default hold multicycle. The 'Same as Multicycle' setting ensures that the signal is latched
on the final edge only. The 'One' setting assumes that the design can latch on any edge, up to and
including the final edge. The 'Same as Multicycle' setting will give fewer hold time violation warnings. The
'One' setting is more restrictive, but it is the default setting for the TimeQuest Timing Analyzer and other
third-party timing analyzers. This setting can be overridden on specific nodes with the Hold Multicycle
option.
