Configuring PeakRDL-BusDecoder

Configuring PeakRDL-BusDecoder#

If using the PeakRDL command line tool, some aspects of the busdecoder command can be configured via the PeakRDL TOML file.

All busdecoder-specific options are defined under the [busdecoder] heading.

cpuifs#

Mapping of additional CPU Interface implementation classes to load. The mapping’s key indicates the cpuif’s name. The value is a string that describes the import path and cpuif class to load.

For example:

[busdecoder]
cpuifs.my-cpuif-name = "my_cpuif_module:MyCPUInterfaceClass"

Command-Line Options#

The following options are available on the peakrdl busdecoder command:

  • --cpuif: Select the CPU interface (apb3, apb3-flat, apb4, apb4-flat, axi4-lite, axi4-lite-flat)

  • --module-name: Override the generated module name

  • --package-name: Override the generated package name

  • --addr-width: Override the slave address width

  • --unroll: Unroll arrayed children into discrete interfaces

  • --max-decode-depth: Control how far the decoder descends into hierarchy
