Im gettin the following during my cts. Can anyone explain what the error and how to get over it? Im using 8.1 Encounter. Any help is greatly appreciated..
Tracing Clock abc/OSOUT ...

CTS cannot proceed. Please check the clock spec files and re-start CTS again
1. This is my first run. I generated clock spec using clockDesign command. It doesnot have any "Excluded pins" in it. As i see from the cts log, i think the tool is assigning "Excluded pins" by itself wherever necessary. Am I right?
2. And in the case of converging clock, only one of the pin should be an "Excluded pin", right? Why declare the other one also as an "Excluded pin"?
