What this CMSIS-SVD inspector resolves
The page reads device-level register defaults, peripheral base addresses, address blocks, interrupts, nested clusters, register fields, and enumerated values. It expands bounded peripheral, cluster, register, and field arrays, applies common peripheral and register derivedFrom inheritance, and calculates absolute byte addresses plus effective field bit ranges.
Overlap and range checks
Expanded registers are checked against register address blocks and against their neighbors using the inherited register width. Explicit alternateRegister aliases are distinguished from accidental collisions. Fields are checked for valid range syntax, fit, and overlap; enumerated values and reset values or masks are checked against their effective widths. Peripheral address-block and interrupt-number collisions remain visible.
Validation boundary
This is a readable preflight, not the CMSIS schema validator. It does not apply the complete XSD, reproduce every SVDConv diagnostic, generate C headers, connect to a target, prove hardware accuracy, evaluate debugger expressions, or fully expand inherited cluster children. Vendor extensions and unfamiliar elements remain outside its semantic checks. Validate release files with the current official schema and SVDConv, then compare important addresses with the silicon reference manual.
Frequently asked questions
Why are there more peripherals or registers than XML templates?
dim, dimIncrement, and dimIndex describe arrays. The inspector expands them so each effective address can be reviewed independently.
Why can two registers share an address?
Some devices intentionally provide alternate views of the same storage. An explicit alternateRegister relationship suppresses the accidental-overlap error; unrelated overlaps remain findings.
Does a clean result prove the SVD matches the chip?
No. A structurally coherent description can still contain the wrong addresses, reset values, access modes, or prose. The reference manual and hardware remain authoritative.
Authoritative references
The hierarchy and inheritance model follow the Open-CMSIS-SVD format specification, including the official peripheral and register and field definitions. Use the official SVDConv utility for full validation and header generation.
