In this paper, a simple model of the energy consumption of RLC tree circuits under exponential inputs is presented. The modeling approach is based on the reduction of a RLC tree network to a proper 2 nd -order RLC equivalent circuit. The extraction of the 2 nd -order RLC equivalent circuit is very simple, thus leading to an efficient model that is suitable for fast simulations.Closed-form expressions of the energy consumption are derived. The resulting expressions allow for understanding the effect of the inductance and the shape of the input waveform on the energy consumption. Extensive SPICE simulations show a typical error lower than 1%, confirming that the model exhibits very good accuracy despite of the simplicity of the adopted approach.

“…Several concerns regarding system modeling and simulation techniques for VLSI interconnect with an RLC higher-order tree networks have been addressed in the literature. Most analyses employ a reducedorder model or other model reduction methods to obtain simulation results for comparison with those obtained from SPICE or HSPICE tools [4][5][6][7][8][9][10][11]. It is forbidden for simulations to use SPICE-like tools to the large number of interconnect line networks.…”

“…The following representations and techniques for analyzing time-domain, dynamic performance, and frequency-domain stability of higher-order RLC-TIN systems, have been widely applied: 1) algebraic equations and differential equations, 2) signal flow graphs and transfer functions, and 3) higher-order reduction and model reduction methods [2,[4][5][6][7][8][9][10][11]. The use of higher-order reduction and model reduction approaches sometimes results in the loss of correspondence to the original physical system structure.…”

A practical and effective novel graphical structural modeling and analysis approach is presented. This approach is used for solving the state interactions modeling problem caused by the model approximations in VLSI interconnect for RLC tree network systems. The bond graph (BG) energy model with a simulink energybased block diagram (SEBD) algorithm is developed. The dynamic behaviors of an example of VLSI interconnect with a 20 th -order RLC tree are presented. Methods of sequent structuring and the delineation of dynamic interactions can be provided for users applying the BG/SEBD algorithms in the development of structural models. It is shown that the new BG/SEBD structural modeling approach requires neither mathematical higherorder reduction nor physically based model reduction. Therefore, useful information can be extracted from the BG/SEBD representation of physical RLC tree network systems. Both time-domain and frequency-domain simulation results are applied to analyze the dynamic response of energy-storing elements using BG/SEBD algorithm combined with Matlab/Simulink software. Finally, a causal analysis of the system zeros plot from the shortest causal path method is proposed, to predict the dynamic response of energy-storing elements and the system performance for design and verification purposes. The dynamic response outputs from different node points were revealed, and the obtained physical information is significant which suggests feasible directions for design (re-design) improvement toward better overall system performance.Keywords higher-order, RLC tree interconnect network (RLC-TIN), bond graph (BG), structural modeling, time-domain and frequency-domain analysis, causality analysis CitationChang R F, Kao W S, Chang C W, et al.

In this paper, a simple and accurate model of the energy consumption in RLC trees with ramp inputs is proposed. The modeling approach is based on the reduction of the RLC tree network to a proper 2 nd -order RLC equivalent circuit, according to the strategy proposed by the same authors in [1]. This approach leads to a closed-form expression of the energy consumption that allows for a deeper understanding of the contribution of the inductance, as well as of the effect of the input rise time.Thanks to its simplicity, the model is well suited for fast energy estimations. Extensive simulations show that the proposed approach is faster than SPICE simulations by four orders of magnitude. At the same time, the proposed approach provides results that are very close to SPICE simulations, with a typical error of 1.5%.
