Talk 1: AI/ML-infused digital IC design workflows on the hybrid cloud
Abstract: As the complexity of modern hardware systems explodes, fast and effective design space explorations for better integrated circuit (IC) implementations is becoming more and more difficult to achieve due to higher demands of computational resources. Recent years have seen increasing use of decision intelligence in IC design flows to navigate the design solution space in a more systematic and intelligent manner. To address these problems, we have been working on AI/ML-infused IC design orchestration in order 1) to enable the IC design environment on hybrid cloud platform so that we can easily scale up/down the workloads according to the computation demands; and 2) to produce higher quality of results (QoRs) in shorter total turnaround time (TAT). In this work, we will illustrate how we provide a scalable IC design workload execution that produces higher performance designs by utilizing AI/ML-driven automatic parameter tuning capability. We first demonstrate that we can build a cloud-based IC design environment including containerized digital design flow on Kubernetes clusters. Then, we extend the containerized design flow with the automatic parameter tuning capability using AI/ML techniques. Finally, we demonstrate that the automatic parameter tuning can be executed in a more scalable and distributable manner using the Ray platform. We will use the actual design environment setups, the code snippets, and results from the product IC designs as evidence that the proposed method can produce a higher quality of IC designs using the Ray-based automatic parameter tuning methodologies.
Talk 2: Pushing the boundaries of material design with RLlib
Abstract: Improving the design and properties of biomedical devices is fundamental to both academic research and the commercialization of such devices. However, improvement of the designs and their physical properties often relies on heuristics, ad-hoc choices, or in the best case iterative topology optimization methods.
We combine material simulation and reinforcement learning to create new optimized designs. The reinforcement learner’s goal is to reduce the weight of an object, but it has to withstand various types of physical forces such as stretching, twisting, compressing, etc. It does so by iteratively pruning a full block of material to reduce the weight. Due to the considerable number of learning iteration steps required, it is vital that the system simulates every iteration in as little time as possible.
The use of RLlib and Ray Tune enables broad-scale parallelization of the reinforcement learning pipeline and deployment on a decentralized computing platform. This allows us to cut the training time by orders of magnitude and the resulting design outperforms the baseline case with several unique designs.
