How to find all clock domain crossings?

[Altera_Forum]

I've been charged with taking over an fpga design from another engineer. This design has 17 clock domains with numerous crossings among its 43 rtl modules spread over 5 levels of hierarchy. I am concerned that some of the clock crossings are not being handled properly, and because the design is full of code evolved from prior designs, I'm facing a daunting challenge to discover and analyze all the crossing points. 

 Is there way to get TQ to report every source/destination register pair that doesn't lie in a single domain? I'm thinking of a report that has something like: from node, to node, launch clock, and latch clock. I could then scan the list and quickly see where to go in the design to check the logic. If there isn't a ready-made means to generate that report, does anyone know a way to "coerce" that information out of TQ?   Any guidance is much appreciated.

TimeQuest ?  Kind regards  GPK

Hi pletz. I use TimeQuest. I probably should have added that I'm familiar with the Report Clock Transfers report, which suggests TQ has intimate knowledge of which signals are crossing which domains. I just need it to go one step further and list them. Maybe I need to go through a two- or three-step process to get what I want, and maybe it's possible to at least semi-automate via TCL, but I'm hoping TQ has something built in that will get me there or that someone will suggest the steps I need go through. I am by no means a TimeQuest expert! Yet!!
