PCB Design Automation
Samsung Electonics, 2019 - 2022
In the existing PCB design, the designer has to do the wiring work manually, and at this time, time and cost are consumed because the design takes into consideration the interference and delay of components and wires. Therefore, in order to avoid spending a lot of time and money on wiring work in PCB design, we developed a PCB design wiring automation technology through an algorithm to reduce the time and cost required for design, increase efficiency, and at the same time satisfy all necessary conditions through the integrity of the algorithm. It aims to ensure the stability of calculating wiring within the target deadline. In this project, the focus is mainly on the design of algorithms and the development of S/W that automates the wiring between CPU-Memory. In order to achieve the objectives mentioned above, algorithm design and S/W development that automates wiring work according to given conditions in PCB design are carried out.
Optimal Data Structure and Algorithmic Applications in Dynamic Geometric Environment
SW StarLab, Institute of Information & Communications Technology Planning & Evaluation (IITP), 2018 - 2022
This project aims to design optimal algorithms that handles data such as objects existing in space. Among them, we are conducting research on designing the optimal geometric algorithm that calculates the shortest path and geometric data structure in a fast time in an environment where objects and data in space dynamically change.
