Overview
A TSMC 130nm Wirebond/Flipchip compatible I/O Library with 5V GPIO, 5V ODIO, 5V Analog I/O and 5V Power Supply I/O.
This silicon-proven, I/O Library features a 5V General Purpose I/O, 5V Open-Drain I/O, 5V Analog I/O, 5V Power Supply and an area efficient 5V ESD protection scheme. The functional cells in the library (GPIO & ODIO) feature an Output Enable pin which, when de-asserted, place the I/O in a HiZ state, and can control multiple modes of output operation with the Output Mode Control pins. The input RX path for this library all have selectable operations between a Schmitt trigger input with hysteresis, a standard buffer with no hysteresis, and a low input voltage mode that can receive a voltage level much lower than the I/O supply without causing metastability or large leakage current. The library has no poly orientation limitations and can be used in any orientation. The library cells are only built up to metal three, but include an metal 4 pad anchor that can be overlaid with either a wirebond or connected to a BUMP. ESD design level are 2kV HBM, 500V CDM and +/-125mA Latch-up.

Certus Semiconductor’s I/O libraries for TSMC’s 22nm ultra-low leakage (22ULL) and 22nm ultra-low power (22ULP) technologies offer robust, high-performance solutions tailored to a wide range of SoC designs — from ultra-low power IoT nodes to demanding consumer and automotive systems. Whether you need low leakage, high drive strength, or analog compatibility, our production-proven IP covers it all.
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.
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.
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.
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.
Post-quantum cryptography (PQC) is moving from theory to engineering reality. With NIST-standardized algorithms ML-KEM (FIPS 203) and ML-DSA (FIPS 204) now finalized, FPGA developers face a practical challenge: How to integrate these algorithms efficiently on resource-constrained hardware?
