Overview

The 1.8V GPIO 3VT library provides general purpose bidirectional I/O cells that are both fault tolerant and 3.3V tolerant. These programmable, multi-voltage I/O’s give the system designer the flexibility to design to a wide range of performance targets.

These libraries are offered at both 16nm and a 12nm shrink. They
are available in a staggered CUP wire bond implementation with a flip chip option.

To design a functional I/O power domain with these cells, an additional library is required – 1.8V Support: Power. That library contains an input-only buffer, isolated analog I/O, and a full complement of power cells along with corner and spacer cells to assemble a complete pad ring by abutment. An included rail splitter allows multiple power domains to be isolated in the same pad ring while maintaining continuous VDD/VSS for robust ESD protection.

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.
