Building block layout based on block compaction and two-adjacent-side channel router

The authors propose a new layout method based on a block compaction and two-adjacent-side channel router for building block VLSI. In this method, the block compaction and global routing are carried out simultaneously and by introducing a new channel router it is possible to avoid unnecessary detour of the wires and reduce the dead space. The present channel routing approach has a remarkable feature that its routability is 100%. Experimental results are shown to compare this method with the previous method
