Configuring PeakRDL-regblock

If using the PeakRDL command line tool, some aspects of the regblock command have additional configuration options available via the PeakRDL TOML file.

All regblock-specific options are defined under the [regblock] TOML 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:

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

default_reset

Choose the default style of reset signal if not explicitly specified by the SystemRDL design. If unspecified, the default reset is active-high and synchronous.

Choice of:

• rst (default)

• rst_n

• arst

• arst_n

For example:

[regblock]
default_reset = "arst"

err_if_bad_addr

If set to true, generate CPUIF error response if a transaction attempts to access an address that does not map to anything.

err_if_bad_rw

If set to true, generate CPUIF error response if an illegal access is performed to a read-only or write-only register.
