Prodigy PGY-JTAG is IEEE 1149.1 JTAG protocol decode software that runs inside a Tektronix oscilloscope. It decodes JTAG activity into TAP states, shows the IR opcode and DR name for each transaction, and links every decoded packet to its waveform. Because it can decode from the digital channels of an MSO, the analog channels stay free to probe other test points and correlate them with JTAG activity. Pertech is the authorized Prodigy distributor.
JTAG decode software highlights
- JTAG protocol analysis from live analog and digital channels or saved files
- Decoded data shown in JTAG state format, with IR opcode and DR name
- User-defined symbols for IR and DR values
- Decoding on digital channels leaves analog channels free for other test points
- Detail view of decoded data together with the waveforms
- Search and filter by state across hundreds of packets
- CSV and TXT export and report generation
Where the JTAG decode software earns its keep
- Debugging JTAG chains and TAP controllers on new boards
- Correlating JTAG activity with power rails or reset signals on the analog channels
- Checking what a debugger or programmer actually sends over JTAG
- Labs with a Tektronix MSO that need JTAG decode without another instrument

Frequently asked questions
What does the JTAG decode software show?
It decodes JTAG activity into TAP states and shows the IR opcode and DR name for each transaction, with your own symbols for IR and DR values, linked to the waveforms.
Which oscilloscopes does PGY-JTAG run on?
It runs inside Windows-based Tektronix oscilloscopes, and uses the digital channels of an MSO for decoding where available.
Why decode JTAG on the digital channels?
Decoding from the MSO digital channels leaves the analog channels free, so you can probe other test points, such as power or reset, and see them in time with the JTAG activity.
Do I also need a JTAG exerciser?
The software analyzes what the oscilloscope captures; it does not drive the bus. To emulate a JTAG device, generate traffic or inject errors, pair it with Prodigy’s JTAG Protocol Exerciser and Analyzer.
