The highest performance debug and trace solution.

Delivery time: approx. 3 weeks


Debug and trace hardware system that enables software debug and trace for the optimization of software running on Arm processor-based targets.

DSTREAM-PT provides an interface between a host such as Arm Development Studio and an Arm processor-based target using a hardware interface such as JTAG or Serial Wire Debug (SWD). DSTREAM-PT also enables the collection of up to 32-bit wide CoreSight-compliant parallel trace for powerful code optimization.

The DSTREAM-PT debug system is made up of a standard Arm DSTREAM-ST unit, along with an additional Arm Parallel Trace probe, enabling:

  • Debug on Arm processors from Arm v.4 to Arm v.8, and CoreSight trace
  • USB 3.0 and remote Gigabit Ethernet host connections
  • Code download speeds of up to 12 Mb per second
  • JTAG clock of up to 180 MHz
  • Serial Wire Debug of up to 125 MHz (standard single-ended signaling)
  • A wide range of target connectors
  • Flexible DDR trace clock timing of up to 300 MHz (600 Mbits/s, per pin)
  • Up to 32-bit parallel trace support (up to 19.2 Gbps maximum trace bandwidth)
  • 8 Gb of trace memory storage on the Parallel Trace probe
  • Real-time dynamic monitoring, to automatically calibrate trace sampling between clock edges
  • Support for up to 1022 CoreSight devices
  • Remote target reset
  • Device bring-up and test utilities
  • Flexible architecture to support third party IP and debuggers


  • Main unit (DSTREAM-ST), High-speed Serial Trace (HSSTP) probe and connecting ribbon cable
  • Unified 5 V power supply unit (PSU) and associated cables
  • Target connectors:
    • 20-pin Arm JTAG connector
    • 14-pin TI JTAG connector
    • 10-pin & 20-pin high-density CoreSight connectors
    • MIPI-60 (QSH) connector
    • Single (16 bit) and dual (32 bit) MICTOR 38 connectors
