Encoder-Decoder Networks for Analyzing Thermal and Power Delivery Networks
نویسندگان
چکیده
Power delivery network (PDN) analysis and thermal are computationally expensive tasks that essential for successful integrated circuit (IC) design. Algorithmically, both these analyses have similar computational structure complexity as they involve the solution to a partial differential equation of same form. This article converts into image-to-image sequence-to-sequence translation tasks, which allows leveraging class machine learning models with an encoder-decoder–based generative (EDGe) architecture address time-intensive nature tasks. For PDN analysis, we propose two networks: (i) IREDGe: full-chip static dynamic IR drop predictor (ii) EMEDGe: electromigration (EM) hotspot classifier based on input power, power grid distribution, pad distribution patterns. ThermEDGe, temperature estimator patterns analysis. These networks transferable across designs synthesized within technology packing solution. The predict on-chip drop, EM locations, in milliseconds negligibly small errors against commercial tools requiring several hours.

Decoupling Encoder and Decoder Networks for Abstractive Document Summarization
Abstractive document summarization seeks to automatically generate a summary for a document, based on some abstract “understanding” of the original document. State-of-the-art techniques traditionally use attentive encoder–decoder architectures. However, due to the large number of parameters in these models, they require large training datasets and long training times. In this paper, we propose ...
متن کاملSynthesis of Cyclic Encoder and Decoder for High Speed Networks
In this paper a parallel implementation of an encoder and of a decoder for cyclic codes to increase the bit rate is proposed. The structures are composed of a cascade of iterative combinational cells able to obtain a finite output sequence spatially. The proposed solution allows high bit rates and high degree of modularity, so an easy integration of the circuits is possible. These characteristi...
متن کاملRED: Reinforced Encoder-Decoder Networks for Action Anticipation
Action anticipation aims to detect an action before it happens. Many real world applications in robotics and surveillance are related to this predictive capability. Current methods address this problem by first anticipating visual representations of future frames and then categorizing the anticipated representations to actions. However, anticipation is based on a single past frame’s representat...

Pixel-wise Ear Detection with Convolutional Encoder-Decoder Networks
Object detection and segmentation represents the basis for many tasks in computer and machine vision. In biometric recognition systems the detection of the region-of-interest (ROI) is one of the most crucial steps in the overall processing pipeline, significantly impacting the performance of the entire recognition system. Existing approaches to ear detection, for example, are commonly susceptib...
