CHAPTER 1
GENERAL
1.1 Overview
1.2 Features
The features of the SM850 are as follows. (1) Evaluation without target By simulating the operations of the target device including the internal peripheral unit operation and interrupt servicing as well as the operation of CPU itself, the logic of the user program can be debugged without an incircuit emulator at an early stage. (2) Supports integrated debugging environment While maintaining the same operability as an in-circuit emulator. (3) Various simulation functions (a) External components By using standard "external components" of peripheral I / Os and I / O blocks used as GUI, such as LEDs, key matrixes, and motors, the simulated environment of the target system can be easily organized. The external components can input or output data during simulation. (b) Architecture of user target system The user logic section in the target system allows user-based architecture (programming) by means of a user-open interface. (c) Data input function Data with timing information created with two types of input editors can be input during simulation. The output result can be displayed as timing charts. (d) Peripheral I / O event and action setting functions Interrupts can be generated and data can be set at any time by using events set to peripheral I / O registers and addresses.
CHAPTER 1
GENERAL
(4) Two types of simulation mode Two types of simulation mode, which can be selected according to the purpose of debugging, are available. (a) Instruction operation mode This operation mode is used only for the simulation of instructions executed at high speeds. It is useful for debugging the logic of the user program. (b) Peripheral operation mode This mode is to verify internal and external peripheral operations while accurately simulating pipeline processing. In this mode, external peripherals dependent on the input / output data and devices are treated as components and as such the operation of peripherals can be visually verified and debugged.
1.3 System Configuration
The SM850 can debug user programs developed for the V850 Family by simulating the operation of the target device without an in-circuit emulator. Moreover, standard "parts" to simulate the target system are also provided with the SM850, so that you can develop the software without having to wait for the completion of production of the target system. (1) Example of system configuration Figure 1-1 shows an example of system configuration of the SM850. Figure 1-1. SM850 System Configuration Example

FUNCTION OF SM850
The SM850 supplies the following external parts: Table 4-1. External Parts Supplied with SM850
External Part Name Button Description A button can be connected to any pin. By pressing the displayed button, an input value can be given to the pin. A key matrix can be connected to any pin, so that data can be input by pressing two or more keys. Can display the output status of a pin connected to the LCD controller / driver incorporated in the device to be debugged in pictures or characters. Can display the output status of a pin connected to the FIP controller / driver incorporated in the device to be debugged in pictures or characters. An LED can be connected to any pin to indicate the output of the pin by lighting or extinguishing. Any value in a specified range can be given to a pin connected to the A / D converter. Any eight pins (seven pins for displaying numerals and one pin for the decimal point) are allocated to a 7-segment LED and one pin is allocated to a digit signal, so that the display of the 7-segment LED changes depending on the value of each pin. The corresponding 7-segment LED lights or extinguishes if the output of the pin allocated to the digit signal is active. A DC motor can be connected to any pin, and revolution or stopping of the DC motor shows the output value of the pin. The total time during which an active value is output is counted from the beginning of simulation and is displayed. A buzzer can be connected to any pin, and the output status can be indicated by the buzzer sound or by a change in the bit map. Hardware reset is executed by clicking the displayed reset button. Any 15 pins (14 pins for displaying numerals and one pin for the decimal point) are allocated to a 14-segment LED and one pin is allocated to a digit signal, so that the display of the 14-segment LED changes depending on the value of each pin. The corresponding 14-segment LED lights or extinguishes if the output of the pin allocated to the digit signal is active. Any internal interrupt can be connected to a button. By pressing the displayed button, the internal interrupt can be generated. Whether a pin is connected to a pull-up / pull-down resistor Can input the PLL input frequency and display the PLL frequency data and the IFC counter, etc. The operation mode and I / O information of the serial interface can be displayed.

CHAPTER 4
FUNCTION OF SM850
4.1.1 Creating external parts The external parts are created in the Parts Window (p.378). Connection between the external parts and pins are made in the dialog box that is opened by the Parts menu on the Parts Window, or by clicking buttons on the tool bar For the details of setting, refer to the explanation on each dialog box. Figure 4-2. Parts Window
4.1.2 Displaying I / O manipulation and I / O results with external parts External parts whose setting has been completed on each dialog box are displayed on the Parts window and serve as an inlet for signals during simulation. By using these displayed parts, the I / O results can be checked and input values can be given to the simulator. For details of the I / O manipulation of each external part, refer to the description of the setting dialog box for each part. I / O manipulation is executed with the Parts window in the execution mode. 4.1.3 Operations of external parts at CPU reset Table 4-2 shows the operations of the respective external parts when a CPU reset is generated from the debugger.

4.1.4 Editing on Parts window On the Parts window, parts can be moved, characters, lines, and rectangles can be written, and the bit map of the external parts can be changed. For editing, select Mode Edit on the Parts window. As a result, the Parts window is set in the location mode in which editing can be carried out. In the location mode, the mouse cursor changes to "+", and a window that indicates the pointer position of the mouse with coordinates (x, y) pops up, and editing is enabled. For the details of editing operations, refer to the description of the Parts window (p.378).
4.2 Data Input Function
The SM850 can input data with timing information to input pin created by using two types of input editors, during simulation. The result output from the simulator can be saved, and can be displayed as a timing chart. 4.2.1 Creating / editing input data The data file with timing information is created or edited in the Input 0 / 1 Editor window or Input timing Chart Editor window. (1) Input 0 / 1 Editor window (see p.354) Data to be input to a pin at any timing is set as a numeric value in 1 bit units. A wait value (input timing) or data input can be set by using a loop.
CHAPTER 4

4.2.2 Downloading of input data file An input data file is downloaded in the Simulation Data Load dialog box (see p.367). Figure 4-5. Simulation Data Load Dialog Box
Note If an input data file is downloaded while an input external part is displayed, input from the input data file takes precedence. If an external part for input is displayed while an input data file is downloaded, input from the external part takes precedence.
CHAPTER 4
FUNCTION OF SM850
The pull-up / pull-down processing can be set in advance by the Pull-Up / Pull-Down dialog box (see p.415). Figure 4-7. Pull-Up / Pull-Down Dialog Box
CHAPTER 4
FUNCTION OF SM850
4.2.4 Output to output data file and data display The output status can be output to a file in the Output Setting dialog box (see p.369). If the timing chart output is checked in the Output Setting dialog box, the Output Timing Chart window (see p.371) is opened, and the output status can be displayed on a timing chart. An identifier (.out) is automatically appended to the output file. Figure 4-8. Output Timing Chart Window
Because the data input to the peripheral I / O registers, as well as the output data from the peripheral I / O registers, can be also saved to the output file, the I / O status can be later checked.
4.3 Peripheral I / O Event & Action Setting Function
The SM850 can generate an interrupt at any timing, or set any data to any address, peripheral I / O register, or pin after a specified event condition has been satisfied, by specifying an event set to any peripheral I / O register or address as a trigger. These settings are reflected during simulation. 4.3.1 Setting event and action An event condition and the operation (action) to be performed after the event condition has been satisfied are set in the IOR Event & Action dialog box (see p.350).
CHAPTER 4
FUNCTION OF SM850
Figure 4-9. IOR Event & Action Window
As an event condition, any address, register name, access status, or access size, or data condition or mask condition can be specified. As an action, an interrupt can be generated at specified timing, or any data can be set to a specified address (address, peripheral I / O register (IOR), or pin). The specified event condition and action are saved to an event condition file (.evn). 4.3.2 Downloading event condition file The specified event condition file is downloaded in the Simulation Data Load dialog box (see p. 367). Figure 4-10. Simulation Data Load Dialog Box
By downloading the event condition file (.evn), an event is registered to the simulator, and the event can be checked during simulation.
CHAPTER 4
FUNCTION OF SM850
4.4 Debugging Functions of SM850
The debugging functions of the SM850 are almost the same as those of the ID850. However, they are slightly different because the SM850 implements debugging through software, without using an in-circuit emulator. (1) Differences in mapping functions The SM850 virtually manages a contiguous memory space same as that of the target device specified on the Configuration dialog box, by allocating an alternate memory on the host machine.
