You can configure the memory in this category.

Figure 2.63

[Memory] Category [Simulator]

(a)

[Memory mappings]

Current memory mapping status is displayed for each type of memory area.

The memory mapping status cannot be changed on this panel. When necessary, you can add a memory mapping in the Memory Mapping dialog box. This dialog box can be displayed by clicking on the [...] button which appears on the right end of the setting field after selecting [Memory Mapping] property.

See the section for the Memory Mapping dialog box for details on how to configure the parameters.

[Access Memory While Running]

You can configure the memory access while executing a program in this category.

The settings of this category are required when using the real-time display update function. See "2.11.1.4 Displaying and changing memory contents during program execution" for details on the real-time display update function.

Figure 2.65

[Access Memory While Running] Category [Simulator]

(a)

[Update display during the execution]

Specify from the drop-down list whether to update the display in the Watch panel/Memory panel during a program execution.

Select [Yes] to update the display (default).

Caution

You cannot change this property while the program is in execution.

(b)

[Display update interval[ms]]

This property is displayed only when the [Update display during the execution] property is set to [Yes].

Specify the interval in 100ms unit to update the contents in the Watch panel/Memory panel display while executing a program.

Directly enter the Integer number between 100 and 65500 (rounding up the fractions less than 100ms) ([500] is selected by default).

Note that if you've changed the specified value of the [Update display during the execution] property from [No] to [Yes], the previous set value is displayed in this property.

Caution

You cannot change this property while the program is in execution.

(3)

[Register]

In this category, make settings related to PC display in the Status bar during program execution.

Figure 2.66

[Register] Category [Simulator]

(a)

[PC display during the execution]

This property specifies whether the PC value is displayed in the Status bar during program execution.

When you select [No], the Status bar under execution will show "Running."

Caution

You cannot change this property while the program is in execution.

(b)

[Display update interval for PC[ms]]

This property is displayed only when you've selected [Yes] in the [PC display during the execution] property.

During program execution, specify a PC display updating interval in the Status bar in 100 ms units.

Enter an integer directly in the range 100 to 65500 (with fractions below 100 ms rounded up). (By default, [500] is specified.)

Note that if you've changed the specified value of the [PC display during the execution] property from [No] to [Yes], the previous set value is displayed in this property.

Caution

You cannot change this property while the program is in execution.

(4)

[Trace]

You can configure the trace function in this category.

See "2.13 Collecting an Execution History" for details on the trace function and this category configuration.

(5)

[Coverage]

You can configure the coverage function in this category.

See "2.15 Measure Coverage [Simulator] [E20 [RX71M, RX66x, RX65x, and RX64M Groups]]" for details on the coverage function and this category configuration.

(6)

[Stream I/O]

You can configure the stream I/O for performing standard I/O or file I/O to/from the user program in this category.

Figure 2.67

[Stream I/O] Category

(a)

[Select stream I/O mode]

In this property, specify an I/O mode from the drop-down list in which mode you want standard I/O to be executed.

To use files for the same low-level interface routines (assembly language part) as the emulator, specify [Emulator mode]. (By default, [Simulator mode] is specified.)

Remark

File I/O is usable only when [Simulator mode] is specified. File I/O cannot be used when [Emulator mode] is specified.

Caution

This property cannot be changed when a simulator is connected.

(b)

[Use stream I/O function]

This property is displayed only when [Simulator mode] is specified in the [Select stream I/O mode] property.

Specify from the drop-down list whether or not to use the stream I/O function while simulator mode is in use.

Select [Yes] when using this function ([No] is selected by default).

(c)

[Stream I/O address]

This property is displayed only when [Simulator mode] is specified in the [Select stream I/O mode] property.

Specify the position at which stream I/O starts while simulator mode is in use.

Directly enter the desired address ([0x00000000] is specified by default).

(7)

[Execution mode]

You can configure the operation that is required in the event of simulation error or exception in this category.

Figure 2.68

[Execution mode] Category

(a)

[Select execution mode]

In this property, you can select the execution mode from the following drop-down list.

Stop

Stops simulation (default).

Continue

Continues simulation (Property items in the bottom section will be enabled.)

(b)

[Stop when undefined instruction exception is encountered]

This property is displayed only when you have selected [Stop] in [Select execution mode] property. Specify from the drop-down list whether to stop when undefined instruction exception is encountered. Select [Yes] if you wish to stop at the occurrence of undefined instruction exception (default).

(c)

[Stop when privileged instruction exception is encountered]

This property is displayed only when you have selected [Stop] in [Select execution mode] property. Specify from the drop-down list whether to stop when privileged instruction exception is encountered. Select [Yes] if you wish to stop at the occurrence of privileged instruction exception (default).

(d)

[Stop when access exception is encountered]

This property is displayed only when an MPU module exists in [Peripheral function simulation module] property and you have selected [Stop] in [Select execution mode] property. Specify from the drop-down list whether to stop when access exception is encountered. Select [Yes] if you wish to stop at the occurrence of access exception (default).

(e)

[Stop when floating-point exception is encountered][The microcontrollers with the FPU]

This property is displayed only when you have selected [Stop] in [Select execution mode] property. Specify from the drop-down list whether to stop when floating-point exception is encountered. Select [Yes] if you wish to stop at the occurrence of floating-point exception (default).

(f)

[Stop when interrupt is encountered]

This property is displayed only when you have selected [Stop] in [Select execution mode] property. Specify from the drop-down list whether to stop when interrupt is encountered. Select [Yes] if you wish to stop at the occurrence of interrupt (default).

(g)

[Stop INT instruction is executed]

This property is displayed only when you have selected [Stop] in [Select execution mode] property. Specify from the drop-down list whether to stop when INT instruction is executed. Select [Yes] if you wish to stop at the execution of INT instruction (default).

(h)

[Stop BRK instruction is executed]

This property is displayed only when you have selected [Stop] in [Select execution mode] property. Specify from the drop-down list whether to stop when BRK instruction is executed. Select [Yes] if you wish to stop at the execution of BRK instruction (default).

(8)

[Instruction decode cache]

In this category, you can configure instruction decode cache, a function which retains decode result during instruction execution so that it can be used again when the instruction at the same address is executed.

Figure 2.69

[Instruction decode cache] Category

(a)

[Increase simulation speed by caching instruction decode result]

Specify from the drop-down list whether to enable instruction decode cache function.

Select [Yes] to enable this function ([No] is selected by default).

Caution

As the instruction decode cache function reuses the decode result, it cannot be used in programs that employ self-modifying code. If an instruction is modified as a result of unintended program operation, error detection may not be performed properly.
