Description

Details Program development method Technical field

The present invention relates to a software development technology, for example, a technology effective when applied to programming of a microcomputer incorporated in a non-contact (contactless) IC card. Background art

In recent years, as an information storage medium that replaces a magnetic card, an IC card having a built-in IC such as a CPU (microprocessor) has attracted attention. An IC card uses a contact-type IC card that receives power, clock signals, and information signals from the reader / writer using contact points and processes commands, and a coil of the reader / writer using a signal transmission method. Non-contact IC cards (hereinafter referred to as “electromagnetic waves”) that receive the generated radio waves (electromagnetic waves) with the coil on the IC card side, generate power, clock, and transmission / reception signals and process commands received from the reader / writer. Contactless IC card ”).

The contact-type IC card is suitable for high-reliability applications that emphasize security, such as electronic money, credit cards, and loyalty cards. Metal contacts are formed on the surface of the contact-type IC card. Information can be read from and written to this contact between the reader and writer.

On the other hand, the non-contact type IC card has IS0 standards established according to the communication distance and communication frequency, and is of the contact type (IS01105336) and the proximity type (IS01444 3) There are two types. Proximity type non-contact IC card The 100% ASK modulation (ASK: ASK: A data) represents data "1" in the presence of a carrier signal with a frequency of 13.56 MHz and data "0" in the absence of a carrier signal. Amplitude modulation) IS014443— A and 10% ASK modulation that represents data “0” with a 90% amplitude signal for a carrier signal with an amplitude representing data “1” IS 014443—There are two types: B.

IS 014443—A modulation method is a method used for contactless IC cards that have a control circuit composed of hardware logic that generally does not have a CPU. In general, IS 014443_A has a simple protocol For IC cards, it is often used for ID cards (personal identification cards) and pre-read cards. On the other hand, IS 01444 3-B type is used for contactless IC cards with a built-in CPU, while IS 014443-B is used for banks with complicated protocols (for example, IS 078 16-T1). It is often used for cash cards and credit cards.

In recent years, with the spread of non-contact IC cards, a combination card that integrates various specifications has been proposed.

As an example of a document described in the non-contact IC force field, there is JP-A-2000-172806.

Source code created based on the software specifications is thoroughly tested by an emulator before manufacturing IC samples. This test is called the Emiyure overnight test. In general, Emiure is generally used for a trace circuit for sequentially tracing the execution state of a user program under development (also referred to as a “target program”), and a break condition set in advance during execution of the user program under development. The break circuit for monitoring whether or not the condition is satisfied, and the operation of the above trace circuit and break circuit are controlled. A user program under development, including an emulation control circuit for controlling, is executed by a microcomputer dedicated to emulation, and the execution state is traced in real time and predetermined break conditions are set. In this way, program development is supported by stopping the execution of the user program at the break condition.

However, although the conventional Emiure for IC cards supports the contact type IC card, it does not support the contactless IC card. It was necessary to separately incorporate an RF circuit to enable transmission and reception by waves. For this reason, in developing a program for a contactless IC card, it is difficult to perform software debugging in the same environment as the actual IC card, that is, to perform emulation based on the actual machine. As a result, for example, even if a good test result is obtained in the Emiyure overnight test of the above source code, there may be a problem in a subsequent IC sample test.

SUMMARY OF THE INVENTION An object of the present invention is to provide a program development method using an emulation which is compatible with an actual machine.

I because it can be combined with a card reader / writer. Even when a card cable does not exist, by using this non-contact wired interface cable, it can be connected to the IC card reader and the cable. In this case, in connection, signals are exchanged in accordance with a predetermined non-contact protocol for exchanging signals in a non-contact state. Emissions in accordance with the standards are possible.

Yet another method of developing a program according to the present invention is to execute a target program to be developed by a computer having a microphone for emulation. Therefore, the first processing to interface with the evening get system by radio waves via the Ic card cable having the antenna coil and the microcomputer for emule evening execute the evening get program to be developed. Therefore, via a non-contact wired interface cable that can be connected to the IC card reader / writer by a conductive line that can transmit a signal that conforms to a predetermined non-contact protocol for signal exchange in a non-contact state. A second process for interfacing with the evening gate system, and a third process for selecting the first process and the second process according to whether or not the antenna coil has been tuned. And

According to the above means, the above I. If the antenna coil has been tuned in relation to the specifications of the card, the first processing described above allows the interface to be connected to the evening get system by radio waves via an IC force cable with an antenna coil. If the antenna coil has not been tuned in relation to the specifications of the IC card, the second process is used to interface with the evening get system via the non-contact wired interface cable. Is done. As a result, even when the tuning of the antenna coil has been completed or not, emulation based on the actual machine can be performed.

The above-described program development method may include a process in which the microcomputer for Emiyure collects information obtained from the evening-get system by executing the evening-get program to be developed.

In addition, the above-mentioned micro computer for the Emiure has an antenna coil by executing a target program to be developed.

The program development method further includes an RF processing unit for interfacing with the evening get system by radio waves via an IC force cable having an antenna coil, and the non-contact wired interface scalable. The RF interface section for controlling the protocol of data input / output performed via the RF section may include a selection process for selectively coupling.

In addition, the above-mentioned program development method includes an RF unit for connecting to a sunset target system by radio waves through an IC cable having an antenna coil, and the above-mentioned non-contact wired interface cable.

A second clock signal for selectively transmitting the first clock signal transmitted via the cable and the second clock signal transmitted via the IC card cable and the RF section to the CPU. The selection processing and the first reset signal transmitted through the non-contact type wired interface cable and the second reset signal transmitted through the IC card cable and the RF unit are performed. Selectively above A third selection process for transmitting to the CPU may be included. According to this, the interface switching of data input / output can be appropriately performed by the third selection processing, and thus emulation according to an actual device can be easily performed. At this time, the high-potential-side power supply detection processing for detecting the level of the high-potential-side power supply, and a clock signal and reset generated inside Emiure based on the detection result of the high-potential-side power supply detection processing And a control process for selectively supplying a signal to the central processing unit. In this case, the clock signal is not supplied to the central processing unit via the RF unit because the IC card cable is separated from the IC card reader. Nevertheless, since the command processing program can be executed based on the internal clock signal of the above-mentioned emulation, software debugging can be performed efficiently.

As the IC card cable, a cable including a card-shaped substrate and an antenna coil formed on the substrate may be used.

Further, a selection process for selecting a plurality of non-contact I0 units based on external inputs, which are based on non-contact protocols of different types, may be included.

As a result, for example, a board having an IC socket on which a sample chip can be mounted is connected to an IC card cable, and this IC power is

The development of the IC system shown in Fig. 1 is not particularly limited, but is shown in relation to the semiconductor manufacturer, IC manufacturer, IC card reader / writer manufacturer, and system manufacturer.

First, when the IC card manufacturer determines the specifications of the IC card system (S11), the IC card reader / writer reads and writes the IC card based on the above IC card system specifications. The specifications of the IC card reader / writer that enable the use of the IC card reader are determined, and the IC reader / writer 14 is manufactured based on the specifications (S12).

According to the specification, a source code which is a source program is generated (S15).

I. Before mass production of cards, verification of programs under development is very important. The operation of the program under development is confirmed in advance by Emiure and IC samples are manufactured before mass production, and the samples are evaluated.

The method of testing by Emiure depends on whether the antenna built into the non-contact IC card has been tuned or not. This is an emulation of a program under development. At the stage of the review, the antenna tuning of the antenna non-contact IC card is not always completed, and if the tuning of the antenna is not completed, the non-contact IC This is because read / write by radio waves is not possible. In view of such circumstances, in this system, it is determined whether or not antenna tuning has been completed (S16), and an emulator system 16 that enables appropriate system debugging according to the determination result is provided. used. The detailed configuration and operation of this Emiure night system 16 will be described later.

If it is determined in the above step S16 that the antenna tuning has not been completed (No), the IC card reader / writer 14 and the card emulation system 16 are used to make contactless communication as described later. An Emiure test is performed using the line-in face (I / F) (S29), and it is determined whether the result of the Emiure test is good (S30). In this discrimination, if it is determined that the result of the above-mentioned Emiyure test is good (Yes), a software mask ROM pattern for IC manufacturing is manufactured (S19). On the other hand, if it is determined in the determination in step S30 that the result of the Emiyure test is not good (No), a failure analysis and its correction are performed (S31).

If it is determined in step S16 that antenna tuning has been completed (Yes), the IC card reader / writer 14 and the IC reader / emulator system 16 are used for details later. An Emiyure overnight test using the non-contact RF interface (I / F) described above is performed (S17), and it is determined whether or not the result of the Emiyure overnight test is good (S17). 18). In this discrimination, If the result of the test is good (Yes), a software mask ROM pattern for IC manufacturing is manufactured (S19). On the other hand, when it is determined in the determination in step S18 that the result of the Emiyure test is not good (No), a failure analysis and its correction are performed (S31), and the result is obtained. Is reflected in the source code.

When the software mask ROM pattern for manufacturing an IC is manufactured in step S19, an IC sample 8 for evaluation is manufactured based on the pattern (S20), and the test of the IC sample 8 is performed. (S22). Although the IC card reader Lai evening 14 is used in the IC sample test, Emiyure Isseki system 16 is not used _c Then, the step S 2 1 of the IC sample test results are satisfactory judged whether or not the line (S22) In the determination of step S22, if the result of the above IC sample test is determined to be good (Yes), mass production of the microcomputer 9 actually mounted on the non-contact IC card is performed. Manufacturing is performed (S23), and integration into a contactless IC card is performed (S24). On the other hand, if the result of the IC sample test is determined to be not good (No) in the determination in step S22, a failure analysis and correction thereof are performed (S31). The result is reflected in the source code.

Non-contact I 0 part 76 A is a Type A method, non-contact 10 part 76 B is a Typ eB method, and non-contact I 0 part 76 C is an I 0 part corresponding to a new type to be added in the future. You. Here, Typ A is not particularly limited, but as shown in FIG. 12, it represents "1" in the presence of a carrier signal having a frequency of 13.56 MHz, and has no carrier signal. Is 100% ASK modulation (ASK: Amplitude Modulation), which means "0". This means I S014443-A, and TypeB means data "1", although not particularly limited. This means IS014443-B, which employs a 10% ASK modulation method that represents data "0" with a 90% amplitude signal for an amplitude carrier signal. Switching of the plurality of types of non-contact 10 units 76 8, 76 B, 76 C is performed by a sunset switching signal TYPESEL from the type switching unit 105 included in the emulation control unit 200. This type switching is performed in the host computer 11 based on the device selection from the selection screen display as shown in FIG. That is, as shown by 150 in FIG. 5, a plurality of types of devices are displayed in a selectable manner, and a desired device can be selected from the plurality of types of devices via an appropriate input device. In accordance with this device selection, the type switching unit 105 transmits I0 portions such as non-contact I0 portions 76A, 76B, and 76C.

The non-contact I0 unit 76A includes a decoding circuit 761, which decodes a received signal input via the multiplexer 87, and a CRC (cyclic circuit) of the decoding circuit 761, as a representative example of the configuration. A reception control circuit 762 that performs reception control including checking using an error correction code composed of codes, a CTL interface (CTL I / F) 763 that enables input and output of control signals, and a bus that is coupled to the bus SRAM (Sticky Random Access Memory) 764, SRAM interface (SRAMI / F) 765 with interface function of SRAM 764, transmission control circuit 766 including CRC generation, etc., transmitted from transmission control circuit 766 Includes a coding circuit 767 for signal coding. The signal encoded by the encoding circuit 767 is transmitted to the RF section as a transmission signal TxD and transmitted to the trace / break circuit 71 for tracing and break processing.

Next, the emulation control unit 200 will be described.

The emulation control unit 200 includes, but is not limited to, a trace / break control circuit 71, a reset / clock control unit 89, a Vdd monitor 72, a reception switching unit 104, and a type switching unit 105.

The trace / break control circuit 71 captures the output data output from the RF interface 613 and the input data input to the RF interface 613 from the RF unit 62 for tracing or break. .

The Vdd monitor 72 compares the level of the input high-potential power supply Vdd with a predetermined threshold value Vth. The comparison result is transmitted to the reset / clock control unit 89. A reset / clock control unit 89 controls selection of a reset signal and a clock signal. The control of the selection of the reset signal and the click signal includes two types of control. The first control is a control for switching the input path of the clock signal and the reset signal between when the IC card cable 13 is used and when the non-contact wired I / F cable 15 is used. The second control is a control for switching the input path between the clock signal and the reset signal based on the monitoring result of the Vdd monitor 72. The reset / clock control unit 89 outputs a reset switching control signal RESSEL for switching the reset signal input path, and the switching control signal RESSEL controls the multiplexer selection operation. Further, a clock switching control signal RESSEL for switching the input of the clock signal is output from the reset clock control unit 89, and the selection operation of the multiplexer 88 is controlled by the clock switching control signal RESSEL.

Here, the first control in the reset and clock control unit 89 will be described.

For example, when it is determined that the antenna tuning has not been completed yet (No) in the determination of step S16 in the flowchart shown in FIG. 1 and the non-contact wired I / F emulator test is performed (S29), the reset is performed. G) Under the control of the clock control unit 89, the reset signal CL—RES and the clock signal CL—CLK captured via the contactless wired 1 / F cable 15 are selected by the multiplexers 88 and 90, respectively. Is transmitted to the CPU 611. As a result, the CPU 611 is reset by the reset signal CL-RES, and operates in synchronization with the clock signal CLCLK after the reset state by the reset signal is released. At this time, the control of the reception switching unit 104 Therefore, the received signal CL—RxD captured via the non-contact I / F cable 15 is selectively input to the RF interface 76 by the multiplexer 87. The reset signal CL—RES and clock signal CL—CLK captured via the non-contact wired I / F cable 15 are transmitted to the CPU 611, and captured via the non-contact IZF cable 15. By inputting the received reception signal CL—RxD to the RF interface 76, the non-contact wired I / F interface test in step S29 can be performed.

If it is determined in step S16 in the flowchart shown in FIG. 1 that antenna tuning has been completed (Yes), and the non-contact RF IF Emiure test is performed (S17), Reset. Under the control of the clock control unit 89, the reset signal RES and the clock signal CLK taken in via the IC card cable 13 and the RF unit 62 are selectively supplied to the CPU 6 by the multiplexers 88 and 90, respectively. 1 is transmitted to 1. As a result, the CPU 6111 is reset by the reset signal RES, and after the reset state by the reset signal is released, operates in synchronization with the click signal CLK. At this time, under the control of the reception switching unit 104, the reception signal RxD from the RF unit 62 is selectively inputted to the RF interface 76 by the multiplexer 87. Thus, the reset signal RES and the clock signal CLK captured via the IC card cable 13 and the RF unit 62 are transmitted to the CPU 611, and the received signal RxD from the RF unit 62 is transmitted to the RF The input to the evening face 76 enables the non-contact RF I / F Emiure test at step S17.

Next, the second control in the reset / clock control unit 89 will be described. This second control is based on the monitoring result of the Vdd monitor 72. It is done.

The Vdd monitor 72 monitors the level of the high-potential power supply Vdd, and if the level of the high-potential power supply Vdd is higher than a predetermined threshold level, the reset / clock control unit 8 The reset signal CL—RES and CK signal CL—CLK captured via the contactless wired I / F cable 15 under the control of 9 or via the IC card cable 13 and RF section 62 The reset signal RES and the clock signal CLK which are taken in are selectively transmitted to the CPU 611. However, when the level of the high-potential-side power supply Vdd is lower than a predetermined threshold level in the level monitor in the Vdd monitorΊ2, the selection control signal RESSEL from the reset / clock control unit 89 is output. , CLK SEL switches the selection state of the multiplexers 88 and 90, and the reset signals EMLRES and EMLCLK generated inside Emiure are selectively transmitted to the CPU 611. Such switching is particularly effective when a non-contact RF IZF emulation test is performed via the IC card cable 13. Hereinafter, a specific example in that case will be described.

FIG. 11 shows the transition of the basic operation state of the main body 12 of the above-mentioned Emiure.

The user program downloaded from the host computer 11 to the main unit 12 of the Emiure is set to an execution state by an execution command input from the host computer 11. As shown in (A) of FIG. 11, since the force-formed substrate 13 B of the IC force cable 13 is separated from the IC card reader-writer 14, the Vdd monitor 72 When the monitored high-potential-side power supply voltage Vdd is lower than the threshold value Vth, the reset clock control unit 89 selects the internal reset signal EMLRES. At this time, the internal reset signal EMLRES is set to low level, As a result, the microcomputer section 61 is kept in a reset state.

On the other hand, as shown in (B) of FIG. 11, the force-shaped substrate 13 B of the IC card cable 13 approaches the IC force reader 14 and the voltage Vdd output from the RF unit 62. Is exceeded by the Vdd monitor 72, the reset signal RES and the quick signal CLK transmitted from the RF unit 62 are respectively RESIN and CL IN As supplied to the CPU 611. Then, when the reset signal RESSIN transmitted from the RF unit 62 is set to a high level, the execution of the user program under development is started in the microphone port computer unit 61. This program execution state is taken into the trace / break control circuit 71, and the trace / break processing is performed.

Also, as shown in FIG. 11 (C), the card-shaped substrate 13B of the IC card cable 13 is separated from the IC card reader / writer 14, and the voltage Vdd OUT output from the RF unit 62 is reduced. If the Vdd monitor 72 detects that the threshold value Vth or less has been reached, the reset signal RESET is switched to the internal reset signal EMLRES by the reset clock control unit 89. At this time, the internal reset signal EMLRES is set to the low level, whereby the microcomputer 61 is reset. When the program shifts from the execution state to the stop state by the program break command of the Emiure main unit 12, the clock controller 89 switches the clock signal CLK IN from CLK OUT to the Emiure internal clock signal EMLCLK. And transmit it to the CPU611. As a result, the CPU 611 executes the command processing program based on the internal clock signal of the above-mentioned Emily, even though the clock signal is not supplied via the RF unit 62. can do. In this state, as shown in (D) of FIG. 11, the card-shaped substrate 13 B of the IC card cable 13 is separated from the IC force reader / writer 14 and output from the RF unit 62. The voltage V dd OUT is maintained as long as it is equal to or lower than the threshold value V th.

As described above, when the card-shaped substrate 13B of the IC card cable 13 is separated from the IC card reader / writer 14, the card-shaped substrate 13B of the IC card cable 13 is formed. IC card reader / writer Approaches 14 again, and then, again, is actually in non-contact by a series of processing when the card-shaped substrate 13 of IC card cable 13 is separated from the card reader / writer 14 By emulating the environment when the IC card 50 is held over the IC card reader / writer 14 on the emulator system 16, it is possible to emulate the actual machine.

Next, the IC sample test environment of step 21 in FIG. 1 will be described.

As a result, the user program under development can be executed on the sample chip 8, thereby performing an IC sample test (S21).

In this way, sample chip 8 in DIP package can be mounted The board 12 having the IC socket 12A for the DIP package is coupled to the IC force cable 13 so that the card-shaped substrate 13B of the IC force cable 13 is formed.
