Abstract :
A data-path generator that generates high-density LSI mask layouts equivalent to hand-crafted ones is described. An entry of the generator is a hierarchical symbolic layout at the gate level. The bit-and-row-slicing technique is a key feature for realizing large-size and high-density data-path generation. A 21 K-transistor data-path whose density is 5.64 KTr/mm2, greater than the 5.38 KTr/mm2 of a hand-crafted datapath, was generated using 1-μm CMOS technology
