The Prodigy xSPI Protocol Exerciser and Analyzer (PGY-STG-PAXSPI) validates and debugs the protocol layer of xSPI and Octal SPI (OSPI) flash and memory interfaces. It captures commands, responses and data at up to 250 MHz in DDR mode through an active probe that puts minimal load on the device under test, and streams the protocol data continuously to the host. A capture can run from power-on through a full transfer, including the switch from single-lane to eight-lane mode, with errors flagged as they happen. Pertech is the authorized Prodigy distributor.
xSPI analyzer highlights
- Captures commands, responses and data in both 1S-1S-1S and 8S-8S-8S modes
- Data capture at 250 MHz in DDR mode, with continuous streaming to the host SSD or HDD for long captures
- Hardware protocol-aware triggers: auto, message and advanced if-then-else multi-level triggers
- On-the-fly validation of the expected command and response sequence
- Decodes command, response, CRC, data, arguments and device registers, with analytics and statistics views
- Monitors two devices at once, at 1.2, 1.8 or 3.3 V
- Trigger out to start an oscilloscope, and a digital input to mark events in the capture
- Upgradable to QSPI, eMMC, SD and SDIO protocol analysis
Where the xSPI analyzer earns its keep
- Bring-up of xSPI and Octal SPI flash and memory controllers in SoCs and MCUs
- Debugging what happens on the bus from power-on, including the change from one lane to eight lanes
- Hunting intermittent CRC and sequence errors that need hours of continuous capture
- Storage teams that want one platform they can extend to QSPI, eMMC and SD

Frequently asked questions
Which interfaces does the Prodigy xSPI analyzer support?
It supports xSPI and Octal SPI (OSPI), decoding 1-bit and 8-bit data in 1S-1S-1S and 8S-8S-8S modes at up to 250 MHz. The same hardware can be upgraded to QSPI, eMMC, SD and SDIO protocol analysis.
Can it capture the boot sequence from power-on?
Yes. The analyzer captures xSPI activity from the power-on state through a full transfer, including the device switching from one lane to eight lanes, and streams it continuously to the host so nothing is lost.
Can it trigger other instruments?
Yes. A trigger out signal fires on any chosen protocol event, so an oscilloscope can capture the electrical waveform at the exact moment of a protocol error.
How does it find protocol errors?
It validates the sequence of commands and responses on the fly and reports any failure, and its search and filter tools jump straight to the packets of interest in a long capture.
