how to troubleshoot circular references?

[zhenqiang]

Hi,I often encounter "circular references" problems,although it can be laid aside because often this problem doesn't has fatal dangerous to my models,but the notification looks uncomfortable to me.

But when I take a deep insight into this problem,I always failed to find which dependency relation is the cause,when I click to open the notification center,I only see the root node listed below "circular references(1)".

So I want to ask for a method to troubleshoot this problem or any modeling principle to avoid this problem?

thanks a lot.

Circular references should never be left in a design! They are extreme high risk to cause huge problems. 

Look for the circular reference text file that is created when the warning occurs. it should be written to the working directory and has a .crc file extension. Open it in a text editor and you will see the loop documented.

You should also use the global reference viewer to help resolve these errors.

I find out that .crc file, open with notepad and it lists the circular features clearly.

thank you very much.
