I korthet

This Master Thesis project at Ericsson focuses on exploring and validating packet timing and data flow within 5G/6G silicon, specifically analyzing timestamping with nanosecond precision. The intern will develop test content to stress data paths, verify synchronization and timestamping accuracy, and port tests to hardware and virtual platforms.

Ansvarsområden

Study the Ethernet interface, on-chip data engines (EMCA, DMA components), and data paths.
Develop test content for sending and receiving packets via the Ethernet PHY.
Drive data paths at maximum throughput for worst-case stress conditions.
Verify synchronization and timestamping accuracy under maximum load.
Exercise DMA components to move data between engines, Ethernet, DDR, and internal RAM at full rate.
Bring up and validate test content on existing project hardware as a proof of concept.
Port test content to the SVP virtual platform for chips under development.
Measure timing accuracy, latency, and throughput.
Document a reusable methodology for the team.

Krav

Master’s student in electrical/computer engineering, embedded systems, or a related field.
Proficiency in programming, particularly in C.
Curiosity about hardware and network operations.
Interest in understanding system behavior at a low level.

Önskade kvalifikationer

Knowledge of Ethernet and packet-based networking.
Familiarity with DMA, memory, and on-chip data paths.
Experience with bare-metal or firmware programming.
Knowledge of synchronization and timestamping (e.g., IEEE 1588/PTP).
Experience with scripting, such as Python, for test automation and analysis.

Förmåner

Hands-on experience with real silicon bring-up.
Skills in high-speed networking, timing, and embedded testing.
A concrete contribution for future Ericsson silicon bring-up.
Experience working alongside hardware design engineers.
