Abstract |
| In this paper we present an algorithm of transistor placement within standard cells. The algorithm is based on enumeration of possible partial placements using a weighted cost function. Partial placements are ordered in a horizontal direction and sorted according to the cost function. The cost function is calculated dynamically. It allows routability estimation without construction of a complete placement. Unfeasible and weak intermediate solutions are eliminated from the consideration. Good intermediate solutions are used for the next intermediate placements until all transistors are placed. The algorithm demonstrated applicability for a wide class of standards cells. The algorithm is used for the industrial standard cell synthesis. |
