Creating and sharing knowledge for telecommunications

Project: Ready-to-Fabricate RF and mmWave Integrated Circuit Layouts

Acronym: LAY(RF)^2
Main Objective:
The LAY(RF)^2 proposes the research, development and test of highly accurate and efficient methods for the automation of radio frequency (RF) and millimeter wave (mmWave) integrated circuit (IC) building blocks. This will be achieved by bringing together the previous work from the involved research teams, and, the knowledge of its members in the areas of: analog, mixed-signal, RF/mmWave IC design in deep nanometer technologies; electronic design automation (EDA); physics and modeling of semiconductor devices; computational intelligence; and also, machine learning (ML). The starting point for LAY(RF)^2 project is AIDASoft, an EDA tool developed by the ICG-Lx research team on the course of several IT projects. However, the latest developments in RF/mmWave IC domains and technologies are bringing new and complex challenges that must be mandatorily incorporated within EDA tools functionalities. The proposed automatic layout-aware methodology with ready-to-fabricate prototypes in-the-loop will be the most complete EDA solution for RF and mmWave IC design to date. While providing fully-automatic functionalities based on advanced computational intelligent and ML techniques, its target is not to drive designers away from their current workspace, but instead, to exploit the full capabilities of well-known and established off-the-shelf CAD tools, i.e., circuit simulator, electromagnetic simulator, DRC, LVS checker, and, layout extractor. By automatically exploring the ready-to-fabricate post-layout design space, re-design iterations can be successfully eliminated, bringing RF/mmWave circuit blocks closer to a first-pass fabrication success as every structure required for tape-out is considered and balanced during the optimization process, ultimately: (1) decreasing design time; (2) reducing design costs; (3) decreasing errors; and, (4) achieving optimal or near-optimal circuit performances.
