Variable Name

Static analysis

Displays the name of the global variable, the static variable inside a file, the static variable inside a function or the class variable (static member variable of a class type) that is defined/referenced in the C/C++ source file.

Up to 1024 characters can be displayed.

The meanings of icons displayed are as follows:

[CC-RX]

If an anonymous union is used, then this will display "<unnamed_N>" as the variable name (N: A number from 1 automatically provided in appearance order).

Class Name

[CC-RX]

Static analysis

Displays the name of the class to which the variable belongs.

If it is a template class, then the number of template arguments are also displayed in the format of "class name<T: the number of template arguments>".

Note, however, that if the variable is not a member variable, or if analysis was not completed, then this will be blank.

Namespace

[CC-RX]

Static analysis

Displays the name of the namespace to which the variable belongs.

If the namespace is nested, then it is displayed in the format of "namespace name::namespace name". If it is an anonymous namespace, then "<unnamed>"is displayed.

Note, however, that if analysis was not completed, then this will be blank.

File Name

Static analysis

Displays the file name (without path) of the C/C++ source file where the variable is definedNote 1.

Note, however, that if it is not defined in a C/C++ source file in project, or if analysis was not completed, then this will display "(No Definition)".

If it is defined in a header file, then the name of the header file is displayed.

Function NameNote 1

Static analysis

Displays the name of the function where the variable is defined.

Note, however, this will be blank for other than a static variable inside a function.

[CC-RX]

In addition to the above, the argument types of the function are also displayed in parentheses "( )". If the function is a const member function/volatile member function, then "const"/"volatile" is displayed immediately after the function name.

File PathNote 1

Static analysis

Displays the absolute path of the C/C++ source file where the variable is defined.

Note, however, that if it is not defined in a C/C++ source file in project, or if analysis was not completed, then this will be blank.

If it is defined in a header file, then the absolute path of the header file is displayed.

PM Information [RH850]

Static analysis

Displays the following information about PE from which the variable can be accessed.

Note that this item appears only when the selected microcontroller version supports multi-core.

ImportNote 1

Static analysis

Displays the following information about the source of the variable information.

See "2.12 Import or Export Information File" for details on the import function.

Access Specifier

[CC-RX]

Static analysis

Displays the access specifier being declared to the member variable.

Note, however, that this will display "-" if analysis is not complete.

The following access specifiers can be displayed.

public, private, protected

Attribute

Static analysis

Displays the variable's symbol attributes/symbol-modifier attributes.

If there are multiple attributes, then they are displayed separated by commas (",").

Note, however, that this will display "-" if analysis is not complete.

The following attributes can be displayed.

Type

Static analysis

Displays the type of the variableNote 2.

If including an alternative name by using "#define statement" or "typedef statement", then not the alternative name but the type is displayed.

Note, however, that this will display "-" if analysis is not complete.

There is no limit to display the number of pointers (up to 4 dimensions for an array can be displayed).

Members

Static analysis

Displays the members of the structure/union.

If there are multiple members, then they are displayed separated by commas (",").

Note, however, that this will display "-" if other than structures/unions or analysis is not complete.

Address

Static analysis

Displays the variable's allocated address in hexadecimal number notation.

The number of digits to display is equivalent to the maximum address value of the selected microcontroller.

Note, however, that this will display "-" if analysis is not complete.

Size[Bytes]

Static analysis

Displays the variable's size in decimal number notation.

Note, however, that this will display "-" for bit variables or the like that cannot be displayed in bytes, or if analysis is not complete.

[CC-RX(V1.xx.xx)]

Variables that are defined only and not referenced will be eliminated by compiler optimization. For this reason, this will display "0" for such variables.

Reference Count

Static analysis

Displays the number of times the variable is referenced in the program, in decimal number notation.

The location where the variable is defined is also counted. The totals for structures, unions, and arrays are displayed at the variable level (references to individual members and array elements are not shown).

In the definition of variables, a line with an assignment statement (e.g. "int variable = 10") is counted.

"variable++;" is interpreted as "variable = variable + 1". Therefore, this variable is counted twice.

Code in C/C++ source files that is referenced but is eliminated by the preprocessor during compilation (e.g. via "#if" or "#ifdef" statements) is not included in the number of references (it is also not output by the search results from [Find All References] in the context menu).

Note, however, that this will display "-" if analysis is not complete.

Read Count

[Full-spec emulator]
[IECUBE]
[E1/E2/E20[RH850]]
[E1/E2 Lite/E20[RX]]
[Simulator]

Dynamic analysis

Displays the number of times the variable was read, in decimal number notationNote 3, 4.

For structures and unions, reads are counted at the structure/union variable level (the number of reads at the individual member and element levels are not shown).

Note, however, that this will display "-" if the debug tool's Trace function is disabled, or if analysis is not complete.

Write Count

[Full-spec emulator]
[IECUBE]
[E1/E2/E20[RH850]]
[E1/E2 Lite/E20[RX]]
[Simulator]

Dynamic analysis

Displays the number of times the variable was written, in decimal number notationNote 3, 4.

For structures and unions, writes are counted at the structure/union variable level (the number of writes at the individual member and element levels are not shown).

Note, however, that this will display "-" if the debug tool's Trace function is disabled, or if analysis is not complete.

Read/Write CountNote 1

[Full-spec emulator]
[IECUBE]
[E1/E2/E20[RH850]]
[E1/E2 Lite/E20[RX]]
[Simulator]

Dynamic analysis

Displays the number of times the variable was read/written, in decimal number notationNote 3, 4.

For structures and unions, reads/writes are counted at the structure/union variable level (the number of reads/writes at the individual member and element levels are not shown).

It may not be possible to analyze reads/writes of variables in segments where variables have been assigned to registers via compiler optimization. For this reason, reads/writes in such sections will not be counted.

Note, however, that this will display "-" if the debug tool's Trace function is disabled, or if analysis is not complete.

Minimum Value

[Full-spec emulator]
[IECUBE]
[E1/E2/E20[RH850]]

Dynamic analysis

Displays the minimum measurement time from the results of program execution, in decimal number notationNote 3.

Only a variable less than or equal to 4 bytes can be displayed.

Note, however, that this will display "-" if for bit type variables/boolean type variables/Bool type variables/structures/unions/arrays/pointer, if the debug tool's Trace function is disabled, or if analysis is not complete.

Maximum Value

[Full-spec emulator]
[IECUBE]
[E1/E2/E20[RH850]]
[E1/E2 Lite/E20[RX]]
[Simulator]

Dynamic analysis

Displays the maximum measurement time from the results of program execution, in decimal number notationNote 3.

Only a variable less than or equal to 4 bytes can be displayed.

Note, however, that this will display "-" if for bit type variables/boolean type variables/Bool type variables/structures/unions/arrays/pointer, if the debug tool's Trace function is disabled, or if analysis is not complete.

Data Coverage[%]

[IECUBE[RL78]]
[Simulator]

Dynamic analysis

Displays the data coverage rates of the variable ("number of bytes accessed in the address range" / "variable size" x 100) (see "3.2 Coverage Results").

The level of shading of the cell's background color indicates the data coverage.

Note, however, that this will display "-" if the debug tool's Coverage function [IECUBE][E20[RX]][Simulator] is disabled, or if analysis is not complete.

Notes 1.

This item does not appear by default.
See "2.6.1 Set the columns to display" for details on how to display this item.

Notes 2.

If including an alternative name by using "#define" or "typedef", then not the alternative name but the original type is displayed.

Notes 3.

Set the [Accumulate result of analysis] property in the [General] category on the [Settings] tab of the Property panel to [Yes] to display the cumulative value for each program execution.

Notes 4.

The calculation is based on the acquired trace data. So for example, if one write to a 4-byte area was output in the trace data as the upper 2 bytes and the lower 2 bytes, then two times will be displayed.

Note

This item does not appear by default.
See "2.6.1 Set the columns to display" for details on how to display this item.

Cautions 1.

Items of the Dynamic analysis information do not appear while disconnecting from the debug tool (default).

Cautions 2.

The [Read Count]/[Write Count]/[Read/Write Count]/[Data Coverage[%]] item for a bit type variable/boolean type variable/_Bool type variable/bit field structure is measured by counting the number of accesses to the address that the variable is being allocated.
Consequently, if bit type variables/boolean type variables/_Bool type variables/bit field structures are allocated to the same address, these items above will display the same value.

Remarks 1.

If static variables inside a function with the same name are declared in a function, they are handled as follows:

Remarks 2.

If you define a static variable in a header file, and include it from more than one source file, information for the header file and all source files is displayed on one line.

Remarks 3.

The display of each type of information can be customized as follows:
- Sort the analysis information
- Filter the analysis information

Remarks 4.

The current row mark ( ) on the left edge of this area indicates that the column in question is the current row.
The following operations can be performed on the current row:
- Jump to Defined Location
- Register Watch-Expressions
- Display List of Referencing Location
- Graph transitions in values
