Precision Power Estimation
Our analysis reveals that Back-Propagation Neural Networks (BPNN) achieve exceptionally low deviations: 0.77% for NAND-based and 1.04% for NOR-based combinational circuits, with Mean Square Errors (MSE) of 0.88751 and 1.08402, respectively. For sequential circuits, BPNN exhibits an outstanding deviation of 0.01% and an MSE of 6.254×10-5.
Random Forest (RF) models demonstrate even superior performance with lower MSEs for combinational circuits (0.115 and 0.26) and significantly better sequential circuit power estimation, achieving an MSE of 1.46E-6 and error rates ranging from 1.4% to 6.8%, compared to BPNN's 4.5% to 68.2%.
Robust AI-Driven Approach
The core methodology involves training two distinct machine learning models: Back-Propagation Neural Networks (BPNN) and Random Forest (RF). BPNN, a supervised learning method, uses a multi-layer feed-forward network with error-correction learning to adjust synaptic weights and minimize errors. Key parameters like learning rate and momentum constant are meticulously tuned across 11 training algorithms.
Random Forest, an ensemble learning method, consists of multiple decision trees. It optimizes precision through hyperparameter tuning, including the number of trees and tree depth, and employs tenfold cross-validation. Actual power consumption values for training and validation are obtained via SPICE/Monte Carlo simulations, with model performance measured using Mean Square Error (MSE) and regression analysis.
Strategic Advantages for VLSI Design
Implementing AI-driven power estimation at early design stages is critical for preventing costly and complex redesigns. The presented BPNN and Random Forest models provide an alternative to traditional, resource-intensive simulations, offering efficient power estimation for large-scale VLSI circuits with significantly lower time complexity.
The Random Forest model's capability to identify the most relevant input features enhances interpretability and facilitates further optimization. These methods are particularly valuable in addressing the challenges posed by increasing design complexity and the demand for gigahertz operating frequencies in modern semiconductor production.

Case Study: VLSI Power Estimation with AI
Challenge: Modern VLSI circuits face increasing design complexity and gigahertz operating frequencies, making power dissipation a critical design constraint. Traditional simulation methods are computationally expensive and unreliable for early design stages.
Solution: This research developed and validated intelligent power estimation models using Back-Propagation Neural Networks (BPNN) and Random Forest (RF). These models were trained on SPICE/Monte Carlo simulated data for various combinational and sequential circuits.
Outcome: The AI models achieved remarkable accuracy. BPNN showed deviations as low as 0.01% for sequential circuits, while Random Forest consistently delivered lower Mean Square Errors (e.g., 1.46E-6 for sequential circuits). This enables designers to precisely estimate power early in the design phase, preventing costly redesigns and supporting efficient, high-performance VLSI development.
