5.9 Profiling Function

• If there is no stack information file (extension is ‘.sni’) that is output from the optimizing linkage editor, only

the functions that have been executed during the profiling data measurement are displayed. For details of the

stack information file, refer to the manual of the optimizing linkage editor.

• The stack size differs from the actual value. It should be used as a reference value during a function call. If

there is no stack information file (extension is ‘.sni’) that is output from the optimizing linkage editor, the

stack size is not displayed.

• While the profiling function is used, software break and on-emulator break, which are event functions, are

not available.

• While the profiling function is used, the parallel access function during user program execution is not

available.

• Since the profiling function internally breaks user program execution, the program is not executed in realtime.

The measured value includes an error.

• [Cycle] displays a decimal value of the counter for measurement of execution time. The resolution for the

counter for measurement of execution time can be set in [Timer Resolution] of the [Configuration Properties]

dialog box. The expression for the execution time of each function is as follows:

Execution time = Value of the [Cycle] item × Value of [Time Resolution]

• To enable the profiling function, [Enable read and write on the fly] must be unchecked in the [Configuration

Properties] dialog box.

5.10 Input Format

5.10.1 Entering Masks

Address bus conditions and data bus conditions can be input with masks. Addresses can be masked in 1-, 3-, or

4-bit units. When a bit is masked, it always satisfies the condition.

To specify a mask for an address bus condition, specify the mask value in the [Mask] area.

The mask for data conditions is similarly specified in the [Mask] area.

To specify any further mask, specify 1 for the digits to be ignored. Examples of mask specification are listed

below.

Input Value Mask Unit Example Masked Bits

Binary 1 bit B’00000111 Masks bits 0 to 2

Octal 3 bits O’000017 Masks bits 0 to 3

Hexadecimal 4 bits H'07FF Masks bits 0 to 10
