Abstract
- Abstract: Regular layouts that follow restrictive design rules are essential to robust CMOS design in order to alleviate many manufacturing induced effects, such as the effect of non-rectangular gate (NRG) due to sub-wavelength lithograph. NRG dramatically increases the leakage current by more than 15X compared to that of ideal physical layout. To mitigate such a penalty, we developed a technique to optimize regular layout through restrictive design rule parameters and to benchmark post-lithography circuit performance. We propose a procedure to systematically optimize key layout parameters in regular layout to minimize the leakage energy with minimal over head to active energy, circuit speed and area. The proposed layout optimization technique is demonstrated with a 65nm technology and projected for 45nm and 32nm technology nodes. Experimental results show that more than 70% reduction in leakage can be achieved with area penalty of ∼10% and 9–12% overhead on circuit speed and active energy. [Copyright &y& Elsevier]
