Overview

Dolphin Technology provides General Purpose I/O IP which cosists of up to 32 I/O ports that can be programmed individually for input, output, or bidirectional operation. Each port can be programmed to trigger the GPIO interrupt on level (high, low) or edge (rising, falling, any) events. The IP serves as additional means of communication between various components of the system on chip (SoC).

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.

Integrating Post-Quantum Cryptography (PQC) on Arty-Z7

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?
