Machine learning methods for fast evaluation of static IR drop effect


Abstract

This paper describes the approach of applying a machine learning model to analyze the static IR drop effect. The problem of static IR drop analysis was solved within the framework of ICCAD Contest 2023(ProblemC). The paper discusses the methodology of ML model training for predicting static IR drop. Various methods for generating a dataset from the SPICE description of circuits for ML model training are proposed. The provided solution to the static IR drop effect problem using machine learning techniques was ranked among the top 3 solutions in the ICCADContest 2023. Two scores, MAE and F1 score, were used to evaluate the obtained results. Compared to the results of static IR drop analysis performed by SPICE modeling, the main score that was used to evaluate the prediction results does not exceed V(MAE). The F1 score has high values up to 0.87.

Notes for potential reviewers

  • Volunteering is not a guarantee that you will be asked to review. There are many reasons: reviewers must be qualified, there should be no conflicts of interest, a minimum of two reviewers have already accepted an invitation, etc.
  • This is NOT OPEN peer review. The review is single-blind, and all recommendations are sent privately to the Academic Editor handling the manuscript. All reviews are published and reviewers can choose to sign their reviews.
  • What happens after volunteering? It may be a few days before you receive an invitation to review with further instructions. You will need to accept the invitation to then become an official referee for the manuscript. If you do not receive an invitation it is for one of many possible reasons as noted above.

  • PeerJ Computer Science does not judge submissions based on subjective measures such as novelty, impact or degree of advance. Effectively, reviewers are asked to comment on whether or not the submission is scientifically and technically sound and therefore deserves to join the scientific literature. Our Peer Review criteria can be found on the "Editorial Criteria" page - reviewers are specifically asked to comment on 3 broad areas: "Basic Reporting", "Experimental Design" and "Validity of the Findings".
  • Reviewers are expected to comment in a timely, professional, and constructive manner.
  • Until the article is published, reviewers must regard all information relating to the submission as strictly confidential.
  • When submitting a review, reviewers are given the option to "sign" their review (i.e. to associate their name with their comments). Otherwise, all review comments remain anonymous.
  • All reviews of published articles are published. This includes manuscript files, peer review comments, author rebuttals and revised materials.
  • Each time a decision is made by the Academic Editor, each reviewer will receive a copy of the Decision Letter (which will include the comments of all reviewers).
