Abstract :
Based on the new concept of crosstalk immunity set (CIS), procedures to minimize capacitive crosscoupling effects are developed for domino logic circuit. The nets in a CIS are by definition free from capacitive crosscoupling effects in any combination of input vectors. New algorithms for CIS identification and CIS-driven phase assignment are proposed to maximize the chance of crosstalk minimization in routing step. Our routing algorithm augmented with CIS information searches for optimal solution to minimize maximum crosstalk the circuit would experience. Experimental results show that the reduction of maximum crosstalk is as much as 30% with CIS-augmented routing
