slang::ast::Scope class

#include <slang/ast/Scope.h>

Derived classes

class CheckerSymbol

Represents a checker declaration.

class ClassType

Represents a class definition type.

class ClockingBlockSymbol

Represents a clocking block.

class CompilationUnitSymbol

The root of a single compilation unit.

class ConfigBlockSymbol

Represents a config block declaration.

class ConstraintBlockSymbol

Represents a named constraint block declaration within a class.

class CoverCrossBodySymbol

Represents the body of a cover cross type, separated out because the members of the cross body can't be accessed outside of the cross itself.

class CovergroupBodySymbol

Represents the body of a covergroup type, separated out because the arguments of a covergroup need to live in their own scope so that they can be shadowed by body members.

class CovergroupType

Represents a covergroup definition type.

class EnumType

Represents an enumerated type.

class GenerateBlockArraySymbol

Represents an array of generate blocks, as generated by a loop generate construct.

class GenerateBlockSymbol

Represents blocks that are instantiated by a loop generate or conditional generate construct.

class LetDeclSymbol

Represents a let declaration.

class ModportSymbol

Represents a modport within an interface definition.

class PackageSymbol

A SystemVerilog package construct.

class PackedStructType

Represents a packed structure of members.

class PackedUnionType

Represents a packed union of members.

class PropertySymbol

Represents a named property object.

class RootSymbol

Represents the entirety of a design, along with all contained compilation units.

class SequenceSymbol

Represents a named sequence object.

class SubroutineSymbol

Represents a subroutine (task or function).

class UnpackedStructType

Represents an unpacked structure of members.

class UnpackedUnionType

Represents an unpacked union of members.

Public types

class iterator

An iterator for members in the scope.

template<typename SpecificType>

class specific_symbol_iterator

An iterator for members in the scope of the specified type.

Collection of information about wildcard imports in a scope.

Public functions

void addMember(const Symbol& symbol)

Adds a symbol as a member to the scope.

void addMembers(const syntax::SyntaxNode& syntax)

Creates and adds one or more member symbols to the scope from the given syntax node.

auto getCompilation() const -> Compilation&

Gets the compilation that contains this scope.

auto getDefaultNetType() const -> const NetType&

Gets the default net type for implicit nets in this scope.

auto getTimeScale() const -> std::optional<TimeScale>

Gets the time scale for delay values expressed within this scope.

auto isProceduralContext() const -> bool

Returns true if this scope represents a procedural context; that is, a procedural block, or a task/function scope.

auto getContainingInstance() const -> const InstanceBodySymbol*

Gets the instance body that contains this scope, if applicable.

auto isUninstantiated() const -> bool

Returns true if this scope is in an uninstantiated context, like if in a module that is not used in the design.

auto addDiag(DiagCode code, SourceLocation location) const -> Diagnostic&

Reports a new diagnostic under this scope.

auto addDiag(DiagCode code, SourceRange sourceRange) const -> Diagnostic&

Reports a new diagnostic under this scope.

void addDiags(const Diagnostics& diags) const

Reports the given set of diagnostics under this scope.

auto find(std::string_view name) const -> const Symbol*

Finds a direct child member with the given name.

template<typename T>

auto find(std::string_view name) const -> const T&

Finds a direct child member with the given name.

auto lookupName(std::string_view name, LookupLocation location = LookupLocation::max, bitmask<LookupFlags> flags = LookupFlags::None) const -> const Symbol*

Performs a full fledged name lookup starting in the current scope, following all SystemVerilog rules for qualified or unqualified name resolution.

template<typename T>

auto lookupName(std::string_view name, LookupLocation location = LookupLocation::max, bitmask<LookupFlags> flags = LookupFlags::None) const -> const T&

Performs a full fledged name lookup starting in the current scope, following all SystemVerilog rules for qualified or unqualified name resolution.

template<typename T>

auto memberAt(uint32_t index) const -> const T&

Gets a specific member at the given zero-based index, expecting it to be of the specified type.

auto empty() const -> bool

Checks whether the scope is empty (has no members).

auto members() const -> std::ranges::subrange<iterator>

Gets the range of members contained in the scope.

template<typename T>

auto membersOfType() const -> std::ranges::subrange<specific_symbol_iterator<T>>

Gets the range of members of the given type contained in the scope.

auto getFirstMember() const -> const Symbol*

Gets a pointer to the first member in the scope.

auto getLastMember() const -> const Symbol*

Gets a pointer to the last member in the scope.

auto getNameMap() const -> const SymbolMap&

Gets the map of names for child symbols in this scope.

auto getUnelaboratedNameMap() const -> const SymbolMap&

Gets the map of names for child symbols in this scope without forcing elaboration of the scope.

void reportNameConflict(const Symbol& member, const Symbol& existing) const

Reports a name conflict between the two given symbols in this scope.

auto getWildcardImportData() const -> WildcardImportData*

Gets the wildcard import data declared in this scope.

Protected functions

void ensureElaborated() const

Before we access any members to do lookups or return iterators, make sure the scope is fully elaborated.

void setNeedElaboration()

Flag the need for this scope to be elaborated before members are accessed.

void addWildcardImport(const WildcardImportSymbol& item)

Add a preconstructed wildcard import to this scope.
