  • Automated design of parallel drive standard cells
    Patent number: 6496965
    Abstract: Methods and apparatuses for automated design of parallel drive standard cells are disclosed. The capacitive load to be driven by a particular output of a standard cell is determined. The driving capacity of the output is also determined. Based on the capacitive load to be driven and the driving capacity, a number of standard cells to be used is determined. The multiple standard cells are coupled in parallel having the respective outputs coupled to the capacitive load to be driven. In one embodiment, the standard cells coupled is parallel are placed such that the connection between the respective outputs and the load are substantially equal.
