clock_tree - innovus

felipe ferreira

Hello everybody,

I'm stuck for a few days with a specific error in my physical implementation for creating the clock tree.

When executing the command " ccopt_design",

I finally get the following error:

Downsizing: ...20% ...40% ...60% ...80% ..**ERROR: (IMPCCOPT-2215): The route/traversal graph for net 'clk' is not fully connected.

Can anyone tell me the best way to fix this kind of situation?

Thank you very much in advance

    Hi, I think so!

    Try to follow to perform the nanoRoute, after this step, do a connectivity test which should indicate that you do not have an open connection.

    It looks like at this stage of the clock tree, it does the routing between the cells you entered to create the clock tree. Routing must ensure that you can make all connections.
    However, I'm not sure about this, if anyone really explains it better
