Simultaneous Statement

The diagrams below draw one box per node kind, with one port per field. The edge colours say how a link is held; they are listed in full on the Fields page.

Iir_Kind_Simple_Simultaneous_Statement

Format: Medium

Accessor	Field	Type	Access	Description
Parent	Field0	Iir	ref	Get/Set the statement in which TARGET appears. This is used to check if next/exit is in a loop.
Chain	Field2	Iir	chain next	—
Label	Field3	Name_Id	owned	—
Simultaneous_Left	Field5	Iir	owned	—
Simultaneous_Right	Field6	Iir	owned	—
Tolerance	Field7	Iir	owned	—
Visible_Flag	Flag4	Boolean	owned	Get/Set the visible flag of a declaration. The visible flag is true to make invalid the use of the identifier during its declaration. It is set to false when the identifier is added to the name table, and set to true when the declaration is finished.

Iir_Kind_Simultaneous_Null_Statement

Format: Short

Accessor	Field	Type	Access	Description
Parent	Field0	Iir	ref	Get/Set the statement in which TARGET appears. This is used to check if next/exit is in a loop.

Label	Field3	Name_Id	owned	—
Visible_Flag	Flag4	Boolean	owned	Get/Set the visible flag of a declaration. The visible flag is true to make invalid the use of the identifier during its declaration. It is set to false when the identifier is added to the name table, and set to true when the declaration is finished.

Declaration_Chain	Field1	Iir	chain	—
Sequential_Statement_Chain	Field4	Iir	chain	—
Attribute_Value_Chain	Field5	Iir	ref	Chain of attribute values for declared items. To be used with Get/Set_Value_Chain. There is no order, therefore, a new attribute value may be always prepended.
Visible_Flag	Flag4	Boolean	owned	Get/Set the visible flag of a declaration. The visible flag is true to make invalid the use of the identifier during its declaration. It is set to false when the identifier is added to the name table, and set to true when the declaration is finished.
Is_Within_Flag	Flag5	Boolean	owned	This flag is set is code being analyzed is textually within TARGET. This is used for selected by name rule.
Has_Is	Flag7	Boolean	owned	Layout flag: true if ‘is’ is present.
End_Has_Reserved_Id	Flag8	Boolean	owned	Layout flag: true if ‘end’ is followed by the reserved identifier.
End_Has_Identifier	Flag9	Boolean	owned	Layout flag: true if ‘end’ is followed by the identifier.

Iir_Kind_Simultaneous_Case_Statement

Format: Short

Accessor	Field	Type	Access	Description
Parent	Field0	Iir	ref	Get/Set the statement in which TARGET appears. This is used to check if next/exit is in a loop.
Case_Statement_Alternative_Chain	Field1	Iir	chain	Chain is composed of Iir_Kind_Choice_By_XXX.
Chain	Field2	Iir	chain next	—
Label	Field3	Name_Id	owned	—
Expression	Field5	Iir	owned	Expression for an various nodes.
Visible_Flag	Flag4	Boolean	owned	Get/Set the visible flag of a declaration. The visible flag is true to make invalid the use of the identifier during its declaration. It is set to false when the identifier is added to the name table, and set to true when the declaration is finished.
Is_Within_Flag	Flag5	Boolean	owned	This flag is set is code being analyzed is textually within TARGET. This is used for selected by name rule.
End_Has_Reserved_Id	Flag8	Boolean	owned	Layout flag: true if ‘end’ is followed by the reserved identifier.
End_Has_Identifier	Flag9	Boolean	owned	Layout flag: true if ‘end’ is followed by the identifier.

Iir_Kind_Simultaneous_If_Statement

AMS-LRM17 11.11 Simultaneous if statement

simultaneous_if_statement ::=
  [ /if/_label : ]
    IF condition USE
      simultaneous_statement_part
    { ELSIF condition USE
      simultaneous_statement_part }
    [ ELSE
      simultaneous_statement_part ]
    END USE [ /if/_label ];

Format: Short

Accessor	Field	Type	Access	Description
Parent	Field0	Iir	ref	Get/Set the statement in which TARGET appears. This is used to check if next/exit is in a loop.
Label	Field3	Name_Id	owned	—
Condition	Field1	Iir	maybe ref	Condition of a conditional_waveform, if_statement, elsif, while_loop_statement, next_statement or exit_statement.
Simultaneous_Statement_Chain	Field4	Iir	chain	—
Else_Clause	Field5	Iir	owned	—
Chain	Field2	Iir	chain next	—
Visible_Flag	Flag4	Boolean	owned	Get/Set the visible flag of a declaration. The visible flag is true to make invalid the use of the identifier during its declaration. It is set to false when the identifier is added to the name table, and set to true when the declaration is finished.
Is_Ref	Flag12	Boolean	owned	Set to True if Maybe_Ref fields are references. This cannot be shared with Has_Identifier_List as: Is_Ref is set to True on all items but the first, while Has_Identifier_List is set to True on all items but the last. Furthermore Is_Ref appears in nodes where Has_Identifier_List is not present.
End_Has_Identifier	Flag9	Boolean	owned	Layout flag: true if ‘end’ is followed by the identifier.
