How to change use clock on nets?

spach

Hi,

     I used CTS to buffer signal nets in my design at place stage. once the buffering was over I loaded the actual CTS spec and proceed furthur but these nets r having use clock property. Now My design is fully routed, Can any one tell a procedure to change use clock property to signal for these nets. 

Regards,

    This blog entry on clock net markings might be helpful.

    There's some good comments there too about nuances related to clock net markings.

    If you load a clock tree spec file and trigger a trace you might be able to get CTS to re-apply the markings.  Another approach is to write the clock tracing to a file, parse it, and apply the clock net markings for each net in the file.

    Hope this helps,
    Bob
