1.25.5

Bug Fixes:

• Do not warn about missing reset on virtual fields. This is usually intentional.
• Fix numerous issues with array & struct UDPs that contain references. Includes fix for #161, and other related issues.
• Fix incorrect reference returned for property refs in array. #164
• Implement proper check for illegal component references embedded in aggregate datatypes in parameters. #114

1.25.4

Bug Fixes:

• Remove overly-strict validation check on fields with access policy sw=w; hw=na;. #155

1.25.3

Bug Fixes:

• Fix bug when processing UDPs that use an array type. #147

1.25.2

Updates:

• Add pre-built binary distributions for Python 3.11
• Throw error if memory's width is not able to be determined. #146
• Fix missing check for address alignment. #141

1.25.1

Bug Fixes:

• Fix unintended behavior of a soft UDP's unassigned default value.
• If UDP is not assigned a value, rather than ignoring the assignment, assign a NoValue token to it. (spec 15.2.1-c)

1.25.0

New features

• UserEnum is now pickleable.
• Upgrade to Antlr 4.11.1 runtime
• Rework compiler's UDP preregistration API
  • Deprecated RDLCompiler.define_udp() method in favor of new RDLCompiler.register_udp()
  • New API allows for "soft" UDP predefinition
  • Better default value & validation hooks
  • See docs for more details: https://systemrdl-compiler.readthedocs.io/en/stable/api/udp.html

Bug Fixes

• Fix ability to define and instantiate signals inside fields. (#131)

1.24.0

New features

• Add more formalized UserEnum.define_new() factory method for use in importers
• Add explicit UserStruct.type_name property.
• UserStruct is now pickleable.

Bug Fixes

• Fix missing error detection if extraneous input is passed to RDLCompiler.expr()
• Rework UserEnum to remove member name restrictions(#130)
• Fix invalid importer identifier check regex.
• Fix UserStruct so RDL inheritance is also represented in Python class inheritance.

1.23.0

New Features

• Add numerous Node methods and properties to make working with aliases easier:
  • RegNode.is_alias
  • RegNode.alias_primary
  • RegNode.has_aliases
  • RegNode.aliases
  • FieldNode.is_alias
  • FieldNode.alias_primary
  • FieldNode.has_aliases
  • FieldNode.aliases
• FieldNode.implements_storage now accounts for aliases:
  • Fields inside an alias register never implement storage
  • A field inside a primary register may inherit additional access modes indirectly from its aliases, and therefore end up implementing storage.
• Enhance walker so that listener callbacks can control walker traversal. Listener callbacks can now optionally return a systemrdl.WalkerAction enumeration to direct how walker should continue.

New Validation

• Numerous rule checks added to check consistency of alias registers and their contents.

Bug Fixes

• Fix elaboration so alias registers inherit primary instance's internal/external type. #123

1.22.0

New Features

• Add RegNode.is_interrupt_reg
• Add RegNode.is_halt_reg
• Include offending text in "illegal name" import exceptions
• FieldNode.implements_storage now returns True for counters, interrupts, and sticky/stickybit fields

New Validation

• Enforce that next property requires field to be hw writable.
• Add check for conflicting edge-sensitive interrupt that uses whole-field sticky property.
• Add check for conflicting sticky/stickybit with we/wel properties
• A field that uses sticky/stickybit properties shall be hw writable
• Illegal to use enable/mask/haltenable/haltmask on non-interrupt fields
• Value of incrwidth/decrwidth shall be between 1 and the width of the counter
• Use of overflow/underflow is pointless on counters that saturate. Emit error.

Bug Fixes

• Fix intr type to return None for non-interrupt fields
• Fix uncaught error if local property assignment is attempted in the root namespace

1.21.0

New Features

• Upgrade to Antlr 4.9.3
• Add FieldNode.is_up_counter and FieldNode.is_down_counter
• Add PropertyReference.width
• Add MemNode.is_sw_readable and MemNode.is_sw_writable (#115)
• Add skip_top option to RDLWalker.walk() method

New Validation

• Improve validation of counter properties
• Add validation of property reference widths
• Require that signals used in resets shall have activehigh/activelow specified
• Flag illegal rclr/rset/woclr/woset properties if field is not readable/writable

Bug Fixes

• Fix default return value for incrvalue/decrvalue
• Fix incorrect validation of incrvalue/decrvalue reference widths
• Fix incorrect spelling of decrsaturate/decrthreshold RHS property references (was previously decsaturate/decthreshold!)
