    routing variations - timing and routing, scaling factor

    routing variations how encounter tool will do the timing and routing if i change scaling factors from (cap)1 to 1.8 and 1 to 1.6(res). how will be the routing if scaling factor is 1 and how it changes from 1.8. what is the difference between them thanks

    slew propagation in cdb.

    we have slew info in .lib,but what is the special in the .cdb slew propagation. how it differs from .lib slew. i mean cdb contains propagated slew and arc current models. my question is how make cdb generates this propagated slew. i think now u can understand the purpose of my question thanks

    65 nm Leakage Problem

    hi all, discussions were good. can anyone elaborate this "More importantly, the leakage (static) is dependent on the VGS on the gate and also the area of the device. So, design with a smaller area and a smaller VGS. In case you are using a transistor which takes logic 1 and logic 0, then use a...
