One of the critical design parameters occurs when a digital signal is converted into an analog signal. As the supply voltage drops to less than 2 times of threshold voltage to reduce leakage and save power, generating a relative large swing with a resistor-ladder DAC becomes more difficult. For a 5 bit DAC, 32 sub-arrays are used to select the appropriate voltage from the series coupled resistor network. Each sub-array uses p-channel transistors where the sub-array extracting the lowest voltage 700 mV only has a 100 mV of gate to source voltage. To compensate for the reduced gate to source voltage, the sub-arrays are partitioned into four groups. In each group, the p-channel width is increased from 2 um to 5 um, as the tap voltage drops from 1.2 V to 0.7 V. This allows the p-channel transistor with a small gate to source voltage to have a larger width thereby improving performance.

A simulation method and system partitions network traffic into background traffic and explicit traffic, wherein explicit traffic is processed in detail, and background traffic is processed at a more abstract level. The packets of explicit traffic are modeled in complete detail, so that precise timing and behavior characteristics can be determined, whereas large volumes of traffic are modeled more abstractly as background flows, and only certain aspects, such as routing through the network, are simulated. Tracer packets are used to model the background traffic and carry a number of characteristics of interest for generating simulation results. These tracer packets are propagated through the network in the same manner as any other simulated packet and therefore are processed through each element traversed by the propagation of the background traffic, but each single tracer packet is representative of all of the packets comprising the modeled background traffic. In this manner, the effect of the background traffic on the explicit traffic can be modeled at each network element. The abstract processing of background traffic is facilitated by techniques that include multi-variate table look-up, neural networks, and the like.
