February 16, 2010 -- Traditional synthesis is coming apart at the seams, especially for designs larger than 20 million gates. Since it relies on gate-level optimization, traditional synthesis is very limited in the size of block that it can handle and so the designer is forced to divide the design into a large number of smaller blocks. However, since place and route can handle much more than these smaller blocks, the synthesized blocks are aggregated back together to bigger blocks. But managing timing and constraints through this process of stitching the blocks together again is very painful, hence almost literally traditional synthesis comes apart at the seams.
