Overview

QSGMII (Quad Serial Gigabit Media Independent Interface) IP from Comcores is a high-speed serial interface developed to aggregate four Gigabit Ethernet (SGMII) ports into a single high-speed serial link using 8b/10b encoding at 5 Gbps. It reduces the number of physical connections needed between Ethernet MACs and PHYs contributing to lowering power and cost.

The IP is compliant with IEEE 802.3, SGMII, QSGMII (as defined by Broadcom) and is targeting ASIC’s and has gone through full UVM verification and is silicon proven.

Key features

What Makes Ethernet IP Truly Automotive-Grade

This blog examines what separates truly automotive-grade Ethernet IP from generic implementations across functional safety, time-sensitive networking, security, observability, lifecycle management, and the integration disciplines that only become visible once a program is deep into development.

Omnitrx introduces Omni500 Ethernet Evaluation Platform, Built on Comcores Expertise

Omni500 supports Time-Sensitive Networking (TSN), multi-speed Ethernet connectivity, and advanced synchronization capabilities essential for modern software-defined systems with time critical processes. It enables testing of TSN end stations, switching functionality, hardware timestamping, and a security features. Omni500 integrates state of the art TSN Ethernet IPs from Omnitrx’s sister company, Comcores.

How Time Sensitive Networking powers the Software Defined Vehicle

Software-Defined Vehicles (SDVs) are turning cars into distributed real-time computing platforms. Instead of dozens of standalone ECUs connected by a tangle of legacy field buses, we now see zonal controllers aggregating local I/O, centralized compute platforms running safety, mission critical software, and a service-oriented middleware layer stretching across the vehicle.

Automotive Ethernet with Comcores – Safety, Quality and ASIL certification of IP

In today’s automotive industry, safety and reliability are non-negotiable. With the increasing complexity of electronic systems in modern vehicles, ensuring compliance with ISO 26262 and Automotive Safety Integrity Level (ASIL) requirements is a demanding aspect of development. At Comcores, we embrace these challenges head-on, combining rigorous processes with a strong commitment to product quality.
