10 Bit Comparator Cell:

Inputs:		A   (10)
		B   (10)

Outputs:	A < B (1)  (active high)

Functional description:

  This cell takes in two unsigned ten-bit numbers and compares their
magnitudes.  If A is strictly less than B, the output line is asserted;
otherwise, the output is deasserted.  The comparator is implemented as two
five-bit counters strung together.

Subcells:  Only the 5-bit comparator

Leaf cells:  (shared)
	2 2-input NOR gates		2 * 4T = 8T
	1 inverter			1 * 2T = 2T

Total:						10T

	(replicated twice)
	5 inverters for input		5 * 2T  = 10T
	5 NOR gates			5 * 12T = 60T
	1 2-in NOR			1 * 4T  =  4T
	1 3-in NOR			1 * 6T  =  6T
	1 4-in NOR			1 * 8T	=  8T
	3 5-in NOR			3 * 10T = 30T
	1 6-in NOR			1 * 12T = 12T

SubTotal:					130T;

Total for entire comparator:			270T
