peakrdl-svd 0.1.0

PeakRDL importer plugin for CMSIS-SVD register description files

peakrdl-svd

A PeakRDL importer plugin that reads CMSIS-SVD (System View Description) register description files and compiles them into the SystemRDL register model.

Installation

pip install peakrdl-svd

Once installed, the plugin registers itself automatically under the svd importer name, so PeakRDL picks it up with no extra configuration.

Usage

CLI

Import an SVD file and export to another format (e.g. IP-XACT):

peakrdl ipxact path/to/device.svd -o out/

Import only a single peripheral:

peakrdl ipxact path/to/device.svd --svd-peripheral UART0 -o out/

Python API

from systemrdl import RDLCompiler
from peakrdl_svd.importer import SVDImporter

rdlc = RDLCompiler()
imp = SVDImporter(rdlc, peripheral_filter="UART0")  # omit filter for full device
imp.import_file("path/to/device.svd")

root = rdlc.elaborate()
for periph in root.children():
    print(periph.inst_name)

Features

• Full device or single-peripheral import via --svd-peripheral
• derivedFrom — peripherals, registers, clusters, and <enumeratedValues>
• Register and cluster arrays via <dim> / <dimIncrement>
• Nested clusters mapped to nested regfile components
• All three SVD bit-range notations: bitOffset+bitWidth, lsb+msb, [msb:lsb]
• Default inheritance — size, access, resetValue, resetMask propagate from device → peripheral → cluster → register
• <enumeratedValues> mapped to UserEnum encoding properties
• modifiedWriteValues and readAction mapped to onwrite / onread

Development
