Considering the voltage drop constraint over a distributed model for power/ground (P/G) network, we study the following two problems for physical synthesis of sleep transistors: t...
Many current designs contain a large number of standard cells intermixed with larger macro blocks. The range of size in these “mixed block” designs complicates the placement p...
