Add to ORKGsigns are requiring buffers to be inserted on interconnects of even moderate length for both critical paths and fixing electrical vio-lations. Consequently, buffer insertion is needed on tens of thou-sands of nets during physical synthesis optimization. Even the fast implementation of van Ginneken’s algorithm requires sev-eral hours to perform this task. This work seeks to speed up the van Ginneken style algorithms by an order of magnitude while achieving similar results. To this end, we present three approxi-mation techniques in order to speed up the algorithm: (1) aggres-sive pre-buffer slack pruning, (2) squeeze pruning, and (3) library lookup. Experimental results from industrial designs show that using these techniques together yields ...
