Timing constraints for ALTLVDS I/O

The Help page wasn't clear whether to use the Input Maximum Delay setting alone (what I thought it meant for this purpose) or in combination with Input Minimum Delay to create a delta that equals TCCS like with TimeQuest. I tried both ways--neither worked. I tried only QII 7.1, but what I was told sounded like Classic Timing Analyzer support for this was dropped a while back. I think TimeQuest is the only way to do it now without a manual calculation to account for the external TCCS.
