SUN Niagara 2 I/O power analysis:
total signal bits: 711
Total FBDIMM bits: (14+10)*2*8= 384
PCIe bits:         (8 + 8)*2 = 32
10Gb NIC:          (4*2+4*2)*2 = 32
Debug I/Os:        168
Other I/Os:        711- 32-32 - 384 - 168 = 95

According to "Implementation of an 8-Core, 64-Thread, Power-Efficient SPARC Server on a Chip"
90% of I/Os are SerDers (the calucaltion is 384+64/(711-168)=83% about the same as the 90% reported in the paper)
--> around 80Pins are common I/Os.
Common I/Os consumes 71mW/Gb/s according to Cadence ChipEstimate @65nm
Niagara 2 I/O clock is 1/4 of core clock. --> 87pin (<--((711-168)*17%)) * 71mW/Gb/s *0.25*1.4Ghz = 2.17W

Total dynamic power of FBDIMM, NIC, PCIe = 84*0.132 + 84*0.049*0.132 = 11.14 - 2.17 = 8.98
Further, if assuming I/O logic power is about 50% of I/Os then Total energy of FBDIMM, NIC, PCIe = 11.14 - 2.17*1.5 = 7.89
 */

/*
 * A bug in Cadence ChipEstimator: After update the clock rate in the clock tab, a user
 * need to re-select the IP clock (the same clk) and then click Estimate. if not reselect
 * the new clock rate may not be propogate into the IPs.
