Concurrent logic restructuring and placement for timing closure
An algorithm for simultaneous logic restructuring and placement is presented. This algorithm first constructs a set of super-cells along the critical paths and then generates the set of non-inferior re-mapping solutions for each super-cell. The best mapping and placement solutions for all super-cells are obtained by solving a generalized geometric programming (GGP) problem. The process of identifying and optimizing the critical paths is iterated until timing closure is achieved. Experimental results on a set of MCNC benchmarks demonstrate the effectiveness of our algorithm.
