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 Timing Analyzer and other third-party timing analyzers. This setting can be overridden on specific nodes with the Hold Multicycle option.
