UMC and Cadence's mmWave Reference Flow Helps Customers Achieve Exceptional 5G RF Design Results

Cadence Design Systems and United Microelectronics Corporation have announced that customers are adopting their certified mmWave reference flow and experiencing exceptional results. As a proof point, mutual customer, Gear Radio Electronics, Asia’s leading RF IP design firm, successfully taped out a low noise amplifier (LNA) IC on the first pass, leveraging UMC’s 28HPC+ process technology and the Cadence® RF solution.

UMC’s production-proven 28HPC+ solution is ideal for high-speed mmWave devices and provides silicon-accurate models for circuit applications up to 110 GHz, such as Gear Radio’s LNA design. The Cadence Virtuoso® RF Solution, incorporating multiple electromagnetic (EM) solvers, enabled Gear Radio to achieve silicon-accurate results. More specifically, Gear Radio utilized the Cadence EMX® Planar 3D Solver, the industry’s gold standard electromagnetic simulator, to accurately model their CMOS design. This resulted in a significantly faster turnaround time between schematic design and post-layout simulation and verification.

Consequently, Gear Radio achieved a first-pass, silicon-accurate design faster than their previous design flow. When Gear Radio compared simulations with the measured silicon results for their 60GHz LNA, metrics such as S21 peak frequency, S21 peak value and noise figure (NF) were within the mid-single-digit range.

The certified mmWave reference flow offers several capabilities via Cadence tools, including:

“Working closely with UMC, we enabled Gear Radio to achieve excellent results with our certified mmWave flow, which includes our industry-leading Virtuoso RF solution, featuring the EMX 3D Planar Solver,” said Ben Gu, vice president, R&D, of the Multiphysics System Analysis at Cadence. “Furthermore, the Cadence foundry team put forth an incredible effort to ensure that our innovative workflow, when deployed with UMC’s 28nm process, adds tremendous value to customers like Gear Radio. While this is Gear Radio’s first silicon-proven design, we look forward to working on many more successful projects together.”

“Simulation of electromagnetic models from EMX together with parasitic extraction information from the Cadence Quantus Extraction Solution, combined in a single, unified cell view within the Virtuoso RF solution, made post-layout simulations much more efficient,” said BJ Kuo, CEO of Gear Radio Electronics. “Moreover, the silicon data demonstrated proven accuracy with UMC’s mmWave models and the Cadence RF solution.”

“The comprehensive mmWave reference flow we developed with Cadence is making RF design faster and easier, and this is evident through customer successes like Gear Radio’s,” said Osbert Cheng, vice president of device technology development & design support at UMC. “Our collaboration with Cadence enabled Gear Radio to create an accurate, innovative LNA design where Gear Radio’s silicon data correlated closely to our models. We are eager to see even more customer successes with our mmWave platform.”
