I-jet Trace provides extensive debugging and trace functionality. It delivers large trace memory capacities and high-speed communication via SuperSpeed USB 3.0. I-jet Trace is equipped with Embedded Trace Macrocell (ETM) trace, supporting all Cortex-M devices with ETM.
I-jet and I-jet Trace has a MIPI-20 connector on the front panel and come with MIPI-20 and MIPI-10 cables, as well as a legacy ARM-20 adapter. For I-jet Trace, only the MIPI-20 cable supports the ETM trace functionality, MIPI-10 and ARM-20 are for plain JTAG/SWD/SWO debugging. For details on the connectors, see the user manual.
In addition, the following adapters are available from IAR Systems to fit different target connectors:
I-scope adds current and voltage measurement capabilities to I-jet and I-jet Trace. The measurements can be done at any designated points on the target board and are displayed in real-time by the C-SPY Debugger in IAR Embedded Workbench.
I-scope measures current and voltages and sends it to I-jet, which synchronizes the data with the program counter of the running application. The data can be graphed and profiled in real time and analyzed using C-SPY. The current sensing is done by connecting two differential current measurement leads across a shunt resistor on the target board.

Please note: I-scope is used in combination with I-jet or I-jet Trace.
