| Popis: |
The paper first analyzes the crosstalk interaction for two RLC-based clock routings with considering both coupling capacitance and mutual inductance. Running results based on 0.13/spl mu/m process show our observations: (a) the difference between clock delays in different frequencies is very small because the damped factor is always larger than 1 for a long-wire clock routing; (b) the crosstalk interaction can be ignored when two parallel segments are far away over than 23/spl mu/m because the difference between segment delays in a unit length is always less than 3%; (c) the clock delay and skew of two-clock routing with considering crosstalk interaction increase up to 19.1% and 108.8%, respectively. Then, we propose a coupling aware algorithm to generate two-clock routing with considering crosstalk minimization simultaneously. Experimental results show that the clock delay and skew can be improved up to 4.4% and 20%, respectively, than that of no any crosstalk minimization. |
