v0.19.0

Release created on: 26.12.2022 - 21:11:29

New Features

• Converted many existing symbol classes to new symbol classes deriving from Name and NewSymbol.
  This simplifies the usage of symbols, as names in VHDL are already very close to symbols.
  ⚠️ NewSymbol will be renamed to Symbol or SymbolMixin once all symbols are converted to the new style.
  • LibraryReferenceSymbol
  • PackageReferenceSymbol
  • PackageMembersReferenceSymbol
  • AllPackageMembersReferenceSymbol
  • ContextReferenceSymbol
  • EntitySymbol
  • ArchitectureSymbol
  • PackageSymbol
• Named entities and new-style symbols now provide a NormalizedIdentifier property.
• Implemented more analyze methods on Design:
  • LinkPackageReferences
  • LinkContextReferences
• Added _references, _contextReferences and _referenced*** fields to Context class.
• Added predefined flag groups to PossibleReference.
• Added _referenced*** fields to DesignUnitWithContextMixin class.
• Added DesignUnits flag for filtering in IterateDesignUnits.

Changes

• Changed PossibleReference from IntEnum to Flag.
• Merged parameters libraryReferencesand packageReferences of class Context to new parameter references.
• A package body now doesn't except an identifier for its name, but a PackageSymbol.
• Improved analyze methods:
  • LinkLibraryReferences
  • LinkArchitectures
  • LinkPackageBodies
• Using ...Identifier instead of ...Name in variables and parameters for a name of an entity. This identifier variable is normalized. In exceptions, ...Identifier is used to print the original name without normalization.
• Improved predefined libraries and packages std.standard, etc.

Bug Fixes

• Added missing initializer for IndexedName.
• Fixed how flag values are combined: + → |
• Fixed example code in README.

v0.18.0

Release created on: 23.12.2022 - 22:38:50

New Features

• Added Document property to DesignUnit.
• Added LibraryReferenceSymbol, PackageReferenceSymbol and ContextReferenceSymbol.
• Added new packages std and ieee containing pre-defined VHDL libraries and VHDL packages.
• Added LoadStdLibrary and LoadIEEELibrary to Design.
• Added IterateDesignUnits generator on Design and Library.
• Implemented various analyze methods on Design:
  • LinkLibraryReferences
  • LinkArchitectures
  • LinkPackageBodies
• Added _Add*** methods to Document.
• Added DesignUnits, VerificationUnits, VerificationProperties and VerificationModes properties to Document.

Changes

• Moved classes:
  • pyVHDLModel.SyntaxModel.Name → pyVHDLModel.Name
  • pyVHDLModel.SyntaxModel.Symbol → pyVHDLModel.Symbol
  • pyVHDLModel.SyntaxModel.Reference → pyVHDLModel.Reference
  • pyVHDLModel.SyntaxModel.LibraryClause → pyVHDLModel.LibraryClause
  • pyVHDLModel.SyntaxModel.UseClause → pyVHDLModel.UseClause
  • pyVHDLModel.SyntaxModel.ContextReference → pyVHDLModel.ContextReference
• Property PrimaryUnit.Library uses it's own private field _library instead of _parent, so _parent can be used to refer to the document a design unit is in.
• Improved EntitySymbol, ArchitectureSymbol, PackageSymbol.
• Improved GetLibrary in Design.
• Improved AddDocument in Library.
• Changed almost all internal lists in Library and Document to dictionaries for quick name lookups.
• Enabled CI job Windows + Python 3.11 again.
