Finding the leaf clock nets in the design

ssuhas

Hi,

I am applying NDR's only to the clock nets. But when I see manually the clock routed after CTS. Only certain clock have been applied NDR.But I have not applied NDR for leaf nets. SO wanted to find the leaf clock nets of the design. Can you please tel me how do we find the leaf clock nets in SOCE.

If possible please let me the changes to be done in the clock speacfication file after applying NDR and performing CTS.

 

Thanks

  •  So, is your LeafRouteType set to Regular, or not set at all? If it's not set at all, I *think* the default is to follow the RouteType, wich means your leaf nets will be double wide. If you've set the leaf type to Regular, then I would just check a few for sanity and be done, personally. If you check a few, you can be fairly certain that what was done to those was done to all of them. But, I did come across a script that should get the leaf nets for you.
