System and methods for placing clock buffers in a datapath stack

A system for placing clock buffers in a datapath stack comprising:

• means for positioning at least one track beside the datapath stack in a netlist;
• means for identifying a location of a clock buffer in the at least one track;
• and
• means for modifying the netlist by connecting at least one datapath macro to the clock buffer on the at least one track.

A computer readable storage medium containing program code for placing clock buffers in a datapath stack comprising:

• a first code segment configured to position at least one track beside the datapath stack in a netlist;
• a second code segment configured to identify a location at which a clock buffer is needed in the at least one track;
• and
• a third code segment configured to modify the netlist by connecting at least one datapath macro to the clock buffer on the at least one track.

A clock buffer placement system for placing clock buffers in a standard cell block comprising:

• logic that positions at least one track beside the datapath stack in a netlist;
• logic that a location at which a clock buffer is needed in the at least one track;
• and
• logic that modifies the netlist by connecting at least one datapath macro to the clock buffer on the at least one track.

A circuitry having clock buffers constructed by the method comprising:

• positioning at least one track beside a datapath stack in a netlist;
• identifying a location at which a clock buffer is needed in the at least one track;
• and
• modifying the netlist by connecting at least one datapath macro to the clock buffer on the at least one track.
