## Modular Machine Learning for Behavioral Modeling of Microelectronic Circuits and Systems

Modern machine learning algorithms are inherently modular. This modularity, combined with the behavioral approach to system design and simulation, will be leveraged to develop mathematical tools for assessing the performance and minimal data requirements for learning a low-complexity representation of the system behavior, one component or subsystem at a time.

## Intellectual Property Reuse through Machine Learning

The objective of this project was to demonstrate that machine learning can be applied to the problem of recasting an analog or full custom digital design from one technology node to another, assuming the same circuit topology.

## Design Rule Checking with Deep Networks

In this seed project, we investigated the feasibility of training a deep convolutional network to perform Design Rule Checking (DRC). By replacing DRC with a recognition network, we hope to greatly speed it up. After showing initial feasibility, in following years, we investigated tying DRC to interactive layout tools.

## Causal Inference for Early Detection of Hardware Failure

Use time-series sensor data to detect wear-out of a hardware component, e.g. HDD or SSD in a storage array. Longitudinal causal inference techniques will omit redundant covariates or features that might be correlated with the failure but do not help in the prediction task.

## Fast, Accurate PPA Model‐Extraction

Earlier work in CAEML (“Applying Machine Learning to Back End IC Design”) will be used to generate models of performance, area and static power. This project focuses on the important missing piece—dynamic power prediction. Parameterized RTL source code and a test-bench with embedded architectural event counters must be provided for each circuit block. This work seeks to eliminate the complicated gate-level simulations presently needed to make accurate predictions of power, which typically occur very late in the design process. This project will develop a comprehensive data mining methodology to maximize the accuracy of PPA predictions while minimizing the data collection effort. A central challenge of this project is to show that high-level events are meaningful predictors of dynamic power.

## High-Dimensional Structural Inference for Non-Linear Deep Markov or State Space Time Series Models

In many applications, a time series of high-dimensional latent vector variables is observed indirectly from noisy measurements. The data are used to predict future failures, and the system can respond accordingly. This project will investigate deep Markov models (DMMs), in which an inference network approximates a posterior probability for the time-dynamics of latent variables by running a multi-layer perceptron (MLP) neural network. We will implement and develop a DMM system that can cope with various types of statistical structure among the features, and pay close attention to scaling the computation as the dimensionality increases.

**Applying Machine Learning to Back End IC Design**

Back end design refers to physical design of an ASIC, including place and route. The goal of this project is to use machine learning to set up the physical design tools on a design by design basis so that optimum results can be achieved with minimal human interaction.
