QSPI Analyzer

The QSPI Analyzer decodes quad SPI flash traces to confirm command sequences, address/data payloads, and mode transitions. It ingests raw trace data from capture tools (logic analyzers, oscilloscopes with SPI decoders) or loader formats and outputs structured event streams with timestamps and edge markers. It supports variants including single, dual, and quad data lines, differing dummy cycles, and common opcodes (READ, PAGE PROGRAM, SECTOR ERASE) per JEDEC conventions. This enables rapid validation in firmware bring-up and hardware debug cycles.

The core algorithm maps captured timing to a precise clock reference, calculates setup and hold margins, clock skew, and data sampling windows. It flags violations such as wrong CPOL/CPHA, misaligned sampling, or improper CS assertion timing. It computes read and write latencies, data throughput, and per-transfer integrity. Outputs include an auto-generated timing diagram conceptually, and optional comparison against device datasheets with suggested mitigations.

Target users include embedded developers, firmware engineers, test technicians, and hardware QA teams performing protocol conformance, stress testing, and regression checks. The tool provides a repeatable, auditable analysis flow: inputting traces, decoding sequences, running timing checks, and exporting reports. Its uniqueness lies in combining opcode decoding with timing margins across single and quad modes, a consistent export format, and a compact summary suitable for test reports and design reviews.
