TOOLS / TEST EQUIPMENT / JTAGULATOR BY GRAND IDEA STUDIO
DESCRIPTION
On-chip debug (OCD) interfaces can provide chip-level control of a target device and are a
primary vector used by engineers, researchers, and hackers to extract program code or data,
modify memory contents, or affect device operation on-the-fly. Depending on the complexity of
the target device, manually locating available OCD connections can be a difficult and time
consuming task, sometimes requiring physical destruction or modification of the device.
JTAGulator is an open source hardware tool that assists in identifying OCD connections from
test points, vias, or component pads on a target device.
This is a high end JTAG reverse-engineering tool! Be careful when using and select the
correct voltages to avoid damaging it.
Module Highlights:
24 I/O channels with input protection circuitry
Adjustable target voltage for level translation: 1.2V to 3.3V
Supported target interfaces: JTAG/IEEE 1149.1, UART/asynchronous serial
USB interface for direct connection to host computer
