SerDes Logging Adapter
SerDes Logging Adapter - our key to the safe validation of autonomous
driving functions
These data have to be interpreted by many control units in the vehicle to enable autonomous driving later. Our SerDes Logging Adapter family (SLA family) supports you in recording the enormous variety of data in test vehicles and using it for various validation phases. As a member of the Automotive SerDes Alliance (ASA), we also promote the standardization of SerDes technology in the automotive market.
The challenge
On the one hand, the difficulty lies in forwarding the data to the receiver control unit with low latency without disturbing normal operation. On the other hand, the data packets must be time-stamped at the same time, optionally compressed live, packaged and finally sent to a data logger.
The solution
- lossless and without noticeable delays to the control unit,
- provides them with high-precision time stamps,
- and passes the data on to a data logger.

SLA accessories

SLA – DCDC – 30W
The galvanically isolated power supply for the SLA is specially designed for automotive test setups and prevents ground loops, especially when using coax signal lines.
- Wide input voltage range.
- Up to 30 W output power.
- Two wake-up pins.

SLA EXTENSION BOX
An SLA Extension Box is used to record additional protocols. The adapter board is often used to record debug interfaces of an ECU or other interfaces parallel to the sensor data.
- Many supported interface types, such as Ethernet RGMII (1Gbit/s), MIPI CSI-2
- High-precision time stamping including external synchronization by SLA.
HiL-Framework
Our software application allows you to unpack recorded sensor data live in your HiL system and finally send it to your ECU (re-injection).
- Used in open-loop HiL environments as data injection.
- Reinjection of recorded scenes stored in PCAP or MDF format.
- High computing efficiency for the lowest possible hardware requirements for the computer.
- Total application data rate up to 15 Gbit/s (3 Gbit/s for each SLA – could be higher or lower depending on the performance of the computer).
- High accuracy time synchronization.
- And more …
Decompression software
Highly optimized OpenCL-based decompression algorithm.
- Uses GPU as well as multi-core and many-core CPU processing power.
- PCAP file format.
- Supports row-based compressed recorded data.
- High performance due to massively parallel processing
Lossless JPEG-1
MDF compression/decompression software
Part of the complete tool chain for validation systems
