0.9V/2.5V I/O Library in TSMC 55nm

A 0.9V/2.5V In-Line I/O Library in TSMC 55LP.

Overview

A 0.9V/2.5V In-Line I/O Library in TSMC 55LP.

This SoundWire Digital I/O Library in TSMC 55nm LP is a silicon-proven interface solution for high-performance au- dio applications. Designed for 0.9V/2.5V operation, the Data, Clock, and Select I/Os, ensuring seamless integration with SoundWire-based systems. Engineered for reliability, the I/O cells meet 2kV HBM, 500V CDM, and 8kV system-level ESD protection (150pF, 330 Ohm direct contact to housing), with 18kV air discharge capability, offering exceptional robustness against electrostatic and environmental stress. This library is ideal for low-power, high-fidelity audio-designs, this I/O library deliver high signal integrity and compliance with industry standards.

GPIO Solutions for CERN’s Radiation-Hardened Applications

For over a decade, Sofics has collaborated with CERN, the European Organization for Nuclear Research. Sofics has delivered advanced GPIO cells tailored for radiation-hardened applications, supporting CERN’s groundbreaking particle physics experiments.

A Generic Solution to GPIO verification

This paper provides a complete solution to the GPIO Verification for any SoC. GPIO interface is available in every ASIC. To avoid duplicate efforts and (save) time to verify the GPIO interface, we have produced this Generic GPIO verification suite. It is a UVM-based verification environment, with all the necessary subcomponents that are required to verify any GPIO design.

How AI and Edge Computing Are Accelerating RISC-V Adoption

One of the critical problems in today’s computing is that transporting data can be more costly in energy and time than computing. With the growing complexity of AI models, SoC designers have shifted their focus toward optimizing memory hierarchies, increasing bandwidth in interconnects, and architecting based on workloads for improved efficiency.

Ensuring reliability in Advanced IC design

To complete our task as engineers we rely on the tools we use. We collaborated with Siemens EDA solutions back in 2025 on a webinar about how we use their tools to develop our designs and layouts.
