Access device for on-chip debugging and tracing

PLS Programmierbare Logik & Systeme is presenting its Universal Access Device 2next (UAD2next) at the fair. It is an access device for on-chip debugging and trace of multicore micro-controllers in embedded systems.

The UAD2next acts as a bridge between the base model UAD2pro and the high-end tool UAD3+. Besides a number of debug and trace interfaces, such as DAP, SWD, JTAG, cJTAG, and LPD, the access device also supports CAN and ASC interfaces for connecting the target. For debugging, PLS uses the concept of its target adapters, which are also optionally available with galvanic isolation. The adaptation covers an I/O voltage range from 1,5 V to 5,5 V.

In addition to recording CAN messages or specific stimulation of the CAN network, the galvanic isolated separate CAN interface also enables communication via DAP over CAN Physical Layer (DXCPL). USB 3.0 and Gigabit Ethernet ports provide data exchange with the Universal Debug Engine (UDE) installed on the PC. Trace modules, which can be plugged in as needed, ensure transfer of trace data from the target into the UAD2next.

Above all, the modules for parallel trace with up to 12 bits width and for serial Aurora protocol with up to two lanes and 1,25 Gbit/s bandwidth ensure data throughput. The data are then recorded into the 512-MiB trace memory of the UAD2next. Trace architectures such as ARM CoreSight, Nexus Class 3 Trace, and Infineon's MCDS (Multi-Core Debug Solution) are supported. The UAD2next is enclosed in an aluminum housing with passive cooling, thus ensuring use in a range of development and test environments. The product will be presented at the Embedded World 2017 in Nuremberg, Germany in hall 4, booth 310.
