Introduction THE I-JET IN-CIRCUIT DEBUGGING PROBE I-jet connects to the target board via a JTAG, SWD, or cJTAG connection, and to the host computer via the USB port. C-SPY debugger C-SPY driver USB connection I-jet JTAG, SWD or cJTAG I-jet communicates using USB 2.0. (USB 1.0 is also supported but not recommended.) The I-jet in-circuit debugging probe is also referred to as a debug probe, debug adapter, or JTAG in-circuit emulator by different tool vendors. -

I-jet Trace Such SI tools will take into consideration the output impedance and rise and fall times of the MCU trace port lines, the length, geometry, and impedance of the PCB traces, the geometry of the layer stack as well as the dielectric properties of the PCB materials to give a simulated graph of the resulting waveform at the trace connector or any other place along the path. - Page 54 They also make the trace impedance matching easier and more consistent. Trace signal requirements I-jet Trace supports DDR (Double Data Rate) clocking mode, which means the data is output on both edges of the TRACECLK signal. To compensate for variations in MCU ETM logic and target board PCB layouts, I-jet Trace contains logic to delay the TRACECLK and each TRACEDATA signal for up to 2.5 ns in 78 ps steps.
- Page 55 Important: The minimum setup and hold times in the table are not as important as the length of the data valid time, because the logic inside the I-jet probe can delay the TRACECLK and TRACEDATA signals as needed, up to 2.5 ns. To get the best results, the trace valid data (Tds + Tdh) should be as long as possible.
