100BASE-T1 Automotive Ethernet Protocol Analyzer

Prodigy Technovations PGY-100BASE-T1 Automotive Ethernet Protocol Analyzer provides passive tapping of 100BASE-T1 Bus. Powerful layer 2 to layer 7 protocol layer trigger capabilities with the flexibility to capture protocol activity over a long period of time makes it easy to debug 100BASE-T1 designs.

Automotive Ethernet interface scales up to address current and future needs of in-vehicle bus speed requirements. The need for the higher-speed in-vehicle bus is increasing to support feature-rich ADAS and connected vehicle needs. Two-wire full-duplex 100BASE-T1 PAM 3 signaling is the choice of interface bus to address these needs. But the 100BASE-T1 bus is difficult to non-intrusively access at the physical layer for protocol analysis. Active tapping of 100BASE-T1 adds Latency and buffering limitation and may not provide real-world timing and protocol layer information to debug the design problems. Oscilloscope based Protocol decode solutions have limitations in buffer size and make it difficult to use in real-world applications due to the low 100BASE-T1 bus utilizations. 

Prodigy Technovations 100BASE-T1 Automotive Ethernet Protocol Analyzer provides an industry-first solution for non-intrusively passive tap the 100BASE-T1 bus at the physical layer and ensures no latency and accurate capturing of protocol data. Powerful basic and multi-level layer 2 to layer 7 protocol trigger capabilities enable the design engineer to capture protocol activity at a specific event. PGY-100BASE-T1-PA supports continuous streaming of captured protocol data to host computer SSD/HDD enabling long-duration capture.

Automotive Ethernet Analyzer Test Setup

PGY-100BASE-T1-PA sniffs the automotive Ethernet bus and monitors the protocol activity between the Master and Slave ECU. Simultaneously monitoring of MDIO and MDC lines and correlating with 100BASE-T1 protocol activity helps easy debugging the design problems. The Automotive Ethernet Analyzer unit will extract bit values from a full-duplex PAM3 signal using Prodigy’s patent-pending solution.  The host computer manages the operation of the analyzer unit, stores, and analyzes the acquired data. Passive tapping of 100BASE-T1 bus ensures the least latency in acquiring the data making this solution is an industry first Passive TAP patent-pending solution.

Powerful Trigger capabilities

PGY-100BASE-T1-PA supports industry best protocol layer trigger capabilities. Users can define a trigger condition at Layer 2 to layer 7. An advanced multi-layer trigger featured with If-then-else if allows the design engineer to monitor more than one trigger condition at the same time.

Protocol Analysis

Ethernet is one of the oldest protocol widely used protocol for many applications. Design engineers are used to viewing and analyzing the protocol data in a specific format. PGY-100BASE-T1_PA Protocol Analyzer software maintains the traditional views and provides advanced analysis capabilities. Lieve decoding capability provides decoding with any DCS error packets.

Analytics of Protocol data

Analyzing Protocol data to identifying the design issues is a challenging task in millions of protocol packets. PGY-100BASE-T1-PA provides statistical information about each layer packet count and error packets. This simplifies the process of isolation of the errors to specific protocol packets or protocol layers. Powerful expression based search capabilities quickly helps in locating packet of interest in the acquired entire protocol data for further analysis.
