Re: Clock Tree Synthesis

this is a file generated by encounter itself when you ar trying to do CTS using CTS mode and then you can save the CTS as .cts.. file.. when you alter the design and you don't need to chagge the clock tree..
In that case u can import that CTS and perform clock routing..

Check whether astro can give .cts.. file i think it does not generates it..

it all for iteration process within that tool..
