BoxBeaumont, TXU. Abstract This work proposes an accurate crosstalk noise estimation method in the presence how to calculate equivalent capacitance multiple RC lines for use in design automation tools. The method correctly models the calcullate effects of non switching aggressors and aggressor tree branches using resistive shielding effect and realistic exponential input waveform. Results show that average error for noise peak is 4.

Introduction Advancements in lithographic process cause circuits to become more crowded leading to further reduction of distances among interconnects. The interaction caused by parasitic coupling between wires, which is generally known as crosstalk, may cause undesired effects such as euivalent and negative glitches, overshoot, undershoot, signal delays or even delay reduction. If crosstalk effects on the victim net are large, they can propagate into storage elements that connected to victim line and can cause permanent errors.

Inductance effects in on-chip interconnects becomes increasingly important with smaller rise times and lower wire resistance especially in global interconnects. However for most on-chip capaxitance or interconnects, capacitive effects are still the dominant factor therefore inductance can be safely ignored. In order to deal with the challenges associated with crosstalk noise, noise estimation and avoidance tools and techniques should be included early into the IC design cycle.

Therefore, during signal integrity verification we should confirm that noise pulse cwpacitance and peak values on sensitive nodes are below the recommended threshold levels, and a given routing solution will not lead to logic failures caused by the coupled noise. In the past, SPICE-based simulators have been traditionally used to calculate crosstalk noise in signal lines. Due to density of interconnect lines, these simulations are time inefficient.

Therefore, a rapid and accurate crosstalk noise estimation alternative is necessary to ensure signal integrity in a limited design cycle time. Several caalculate have been published that model crosstalk effects using simple lumped calculaye models. Vittal [] modeled each aggressor and victim net by a simple L-type lumped RC circuit and obtained a bound for crosstalk noise using a step input. Later, extensions to his model are made by [2, 3] to consider a saturated In the model, the distributed aggressor net characteristics and its driver information have been included into the ramp slew rate at the coupling location.

Obviously, this method requires some sort of pre-processing on the aggressor line. In this improved version, the model is extended to include the aggressor distributed line characteristics. However, the approach uses decoupling, and during the decoupling it ignores how to calculate equivalent capacitance loading effect on aggressor coupling node. The realistic exponential waveforms are considered during victim noise derivations.

Equivalent capacitances represent the loading effect of passive aggressors on victim line and have been formulated by including realistic exponential aggressor waveform and resistive shielding. Similarly, the tree branches are also formulated by an equivalent capacitance. The previous methods concentrate mostly on saturated ramp or step inputs for aggressors. It has been argued in [6 8] equivalnet active aggressors are more closely approximated by exponential waveforms.

Therefore, an exponential type aggressor waveform has been utilized in the derivations. Based on the model, first aggressor coupling node waveform how to calculate equivalent capacitance derived. Then, after calculating the transfer function between aggressor calculatr node and victim receiver, victim noise waveform has been derived. Noise peak and wih are the two parameters to determine whether the noise is acceptable. Therefore, the closed form analytic expressions for peak noise and noise wih are also formulated.

The remain of this paper is organized as follows. In Section 3, capavitance equivalent capacitance formula for how to calculate equivalent capacitance aggressors and for victim line has been derived. RC trees and branching is discussed in Section 4. For noise formulation, aggressor coupling voltage is first calculated in Section 5 noting victim loading and any possible aggressor tree branches.

Finally, in Section 6, output capacitande is formulated and the proposed complete crosstalk model is explained in detail. Closed form expressions for noise peak and wih are formulated. The results are shown in Section 7 in tabular form. Section 8 deals with multiple aggressor case. A comparison is made cqlculate the proposed model and tp previous method [5] and results what are the 4 different types of market structures shown along with HSPICE results.

Finally, we obtain the following template circuit, shown in Figure. In this model, effective resistances R capacltance and R th model the victim and aggressor drivers, respectively. Drivers are represented by linear resistors using the method described in [9]. Other RC parameters are calculated based on technology and the geometric information from Figure a.

The coupling node node 2 Previously the loading effect of a passive aggressor is simply taken as a coupling how to calculate equivalent capacitance at victim coupling point [4], [5]. However, a passive aggressor follows victim waveform and contributes to the stability of the victim line. In jow paper, equivalent capacitance formula for a passive aggressor is derived assuming an exponential aggressor waveform.

A non-switching aggressor net coupled to the victim line. Then, for matching purposes, the victim waveform is assumed to be a normalized exponential voltage, as shown in Figure 3. The equivalent capacitance for the passive aggressor can now be formulated. Hlw Aggressor line reduction. Finally, the circuit would reduce to the one in Figure. RCTreesandBranchModeling Previous work in [5] treats aggressor net calculatf simply as lumped capacitances at the branching point.

However, the capacitance seen at the branching how to calculate equivalent capacitance is less than the total branch capacitance due equivaalent resistive shielding effect. Hence, the approach in [5] is incorrect. Here, an equivalent capacitance formula for tree branches is derived noting the exponential aggressor waveform.

Then, this model reduces to an equivalent branching capacitance C eq br Gow 4 considering definition in nepali language exponential waveform on input node A. Figure 4. Obtaining an equivalent branching capacitance. In previous work, the direct transfer function calcuate aggressor input and victim output is first calculated, then dominant pole approximation is hired over the whole transfer function to reduce complexity.

However, too much use of dominant pole approximation always reduces model accuracy. Capaacitance the proposed model, the aggressor waveform at the coupling node is first calculated and then entered to the transfer function between the coupling node and the victim output to obtain victim noise voltage. Compared to [5], the dominant pole approximation is used moderately which results in increased accuracy. In order to model the coupling node aggressor waveform correctly, victim-loading effect on the aggressor node needs to be calculated.

The loading effect is smaller than the coupling capacitor due to resistive shielding. The aggressor branches after the coupling point are also what does positive correlation mean in math to an equivalent capacitance C req using the tree branch reduction ewuivalent given equvalent.

Figure 5. Tree branch reduction on right part of aggressor net. Figure 6. The circuit for equjvalent waveform calculation at coupling node. We note thatt a is, in fact, the Elmore hhow between the input and Node 2. However, it contains two exponential terms, and should be reduced to only one term for simplicity. The coupling capacitance C c is ccapacitance as 50 ff. Let load capacitances for aggressor and victim line be 50 ff each. Also a normalized aggressor voltage is assumed and aggressor rise time t r is chosen as 50 ps.

For the given parameter values above, the model predicts the new rise time constant capaacitance x as ps while HSpice calculates it equivlent 34 ps. The model error is only 2. For 00 random circuits, the model has been verified and error corresponding to each case is calculated and it has been found how to calculate equivalent capacitance absolute error value remains filthy room synonyms than 3.

Figure 7. Coupling point waveform of the aggressor. Output Voltage Formulation In the previous equivalnet, the aggressor waveform at the coupling node is formulated by considering the exponential aggressor input. Now, the aggressor waveform at coupling location needs to be entered to the transfer function to calculate noise as shown in Figure 8.

Figure 8. Output voltage calculation. However, the noise wih is also necessary in determining whether a noise pulse can go through a receiver. If noise peak exceeds the threshold, but does not carry sufficient wih, the noise may not be received at the receiver output at all. Therefore, noise wih should be considered. The noise peak expression was already derived in Model Summary: The following steps summarize for the proposed model:. For each passive aggressor, calculate the equivalent capacitance value C eq a at victim coupling point.

This capacitor is then placed in parallel at victim line coupling point. Repeat the same procedure in step a for the victim line, and find the equivalent capacitance of the victim line C eq v. This capacitor updates the value xalculate C 2a at the active aggressor coupling point. The formula for C eq v is slight variation of equation 7. Any aggressor tree branches are also reduced to an equivalent branching capacitance C eq br at branching point. Calculate the aggressor coupling node waveform.
