Typical Setups

Type-C Communications and Voltages
Products under test (PUTs) are connected to the Type-Creceptacles on the front panel of the Tracker, with a Control Computerconnected to the Tracker for power and application control. All supportedtraffic is captured and uploaded real-time to the Control Computer. Gigabitsignaling is passed through the analyzer. Conveniently, the Tracker’s captureengine will automatically determine which Type-C Communications Channel (CC)pin is being used for USB Power Delivery com­munications and which pin is beingused for Vconn. Various protocols operating over the Type-C Sideband Use (SBU)lines are also captured, in addition to USB 2.0 traffic. A special cable (notshown) is supplied to manage proper signal routing.

Logic Signals, TCPCI/I²C, andOther Serial Protocols
The Logic connection can be used to capture logic /general purpose IO signalsand several protocols, such as I²C, UART, SWD, and SPI. This trafficis displayed in various windows throughout the Tracker software application,including protocol-specific Overviews and the Instant Timing view, for variousprotocol analyses and precision timing-related characterizations. All LogicConnection traffic and signaling can be captured concurrently and in precisesynchronization with all other Logic Connection inputs as well as all capturedfront-panel Type-C traffic (CC, SBU, and USB 2.0), including voltage states.Logic signals captured can be grouped into user-named buses for addedconvenience.

Protocol Analysis

Captured protocols and voltages, along with captured logicsignals, are presented to the user real-time by the Ellisys applicationsoftware. An assortment of displays provides an intuitive understanding oftraffic, protocol sequences, performance criteria, error conditions, electricalcharacteristics, timing details, standard/class decoding, protocol decoding,and more.

The physical capture of supported communications is accomplishedusing latest-generation hardware capture technology to non-intrusively tap andreliably pass through supported protocols while passively passing gigabittraffic.

Integrated Logic Analysis

The integrated logic analysis provides developers with efficientand convenient visualization of external digital signals (such as discrete outputsof FPGA/ ASIC) in synchronization with all other captured traffic. CapturedGPIOs can be grouped into buses and given user-defined names for easyidentification.

Precision TimingCharacterization

All protocol traffic, logic signals, and voltages of Type-Csignaling and power lines (CC, Vconn, SBU_A, SBU_B, and Vbus) are tracked usingthe Instant Timing view. These events are perfectly synchronized with eachother and with the Overview windows. Precision timing measurements can be madebetween any events within the Timing view to precisely characterize timings.Throughput and statistical information is also provided. Events selected in theOverviews are highlighted and aligned to the Instant Timing view.

Voltage State Tracking

Tracking Type-C electrical signaling is crucial to understandstate machine behaviors. Timings and voltage levels of the various Type-Csignaling and power lines have specific meanings and purposes. When notproperly implemented, they can wreak havoc with an implementation.Additionally, it is important to precisely relate these voltage values andstates to protocol events for performance characterizations and debugexercises. The Type-C Tracker application provides accurate monitoring of Vbus,Vconn, SBU_A, SBU_B, and CC in the Instant Timing view, associated with anycaptured logic signals and protocol packets and events.

Alternate Mode Traffic

USB Power Delivery protocol provides a wide array of mechanismsto negotiate power, and can also be used as a sideband channel for standard andvendor-defined messages. Additionally, Power Delivery provides methods todiscover, enter, and exit alternative modes, identified by a unique identifier(SVID) and defined by vendors or standards bodies outside of the scope of theUSB Implementers Forum (USB-IF). The Type-C Tracker supports capture anddecoding of ALT Mode entry, discovery, and exit protocols as well as ALT Modecommands. Additionally, the Tracker supports several ALT Mode protocols thatare conveyed over the Type-C sideband lines (SBU_A and SBU_B), includingDisplayPort Auxiliary (AUX) traffic and UART for Thunderbolt 3.

Type-C Port Controller and I²C

Located between a Type-C Port Manager (TCPM) and a Type-C PortController (TCPC), the Type-C Port Controller Interface (TCPCI) is astandardized connection between I²C devices. The Type-C Trackercaptures and decodes TCPCI traffic over the Logic GPIO connection, and can beconfigured to capture other vendor-specific I²C protocols (multiplesuch protocols, concurrently).

UART, SPI, and SWD Protocols

The Type-C Tracker supports capture of UART, Serial Pe­ripheralInterface (SPI), and Serial Wire Debug (SWD) protocols over its logicconnection interface. Traffic captured is displayed in tight synchronizationwith all other traffic captured by the analyzer. Detailed decoding is providedand each protocol is displayed chronologically in dedicated Overview windows.
