[Prior Art] In general, a VLST system What takes time in the design of a system is verification and testing of the system.The reason for this is that the computer calculation time required for various simulations
This is because errors in modeling the actual circuit were a problem. In order to solve these problems, it has been proposed to perform system verification and testing using an actual circuit. To configure an actual circuit, for example, as shown in FIG. 8, a central microprocessor (CPU) 10 chip, a large number of various general-purpose integrated circuits (IC) 12 such as TTL, RAM, ROM, etc., and Peripheral circuits consisting of a very small number of small programmable logic devices (PLDs) 14 used for address records, etc. are combined for each system design, placed on the system board 161, and wired by soldering using printed wiring or jumper wires. For example, it has been considered to use a breadboard consisting of a one-board computer. However, if such a dedicated breadboard is made for each system, the scale of integration is large and the number of built-in logic circuits is large, so it takes a lot of time and money to make a breadboard equivalent to the system. However, when the system is changed, it is difficult to make corresponding modifications. In order to solve such problems, for example,
The 49831 is equipped with a memory element that defines the connection relationship between a plurality of logic devices, and by making the contents of the memory element changeable from the outside, the internal wiring can be freely rearranged as needed to create various An electronic device is disclosed that is adapted to implement the logical functions of. Furthermore, Japanese Patent Application Laid-Open No. 63-50999 is equipped with a fuse that defines the connection relationship between a plurality of logic devices, and by making it possible to access the fuse from the outside, the internal structure can be closed as needed. An electronic device has been disclosed in which wiring can be freely assembled to realize various logical functions. These electronic devices are equipped with sockets for installing logic devices such as programmable read-only memory (PROM) and MSI, and are equipped with wiring that connects these sockets vertically and horizontally. Since a wiring exchange device is placed at the intersection, any wiring can be exchanged. In addition, in Japanese Patent Application No. 1-14.2382, the inventors of the present invention proposed that a large number of module sockets of the minimum unit of standardized size and number of bins are regularly arranged side by side, and the distance between the terminals of the module sockets is The present invention proposes a technology related to an adapter for a configurable electronic circuit board (hereinafter referred to as a board adapter) that is inserted into the module sockets 1 to 1 of a board connected by simple wiring. In this technology, as shown in FIG. 10 (A), a board adapter is inserted into the module socket via an adapter pin A, and has an adapter socket A' into which an electronic circuit component C can be inserted and mounted. Or, Figure 10 (B
), wiring determining means a for determining the wiring connection between the adapter pins A inserted into the module sockets (that is, between the module sockets inserted);
A technology has been proposed in which electronic circuit components of any size can be placed at any position on the board by using a board adapter or the like having a board, and changes can be made extremely easily. ing. [Problems to be achieved by the invention] However, in the above-mentioned JP-A-63-49831 and JP-A-63-50999, the wiring exchange device is not made into a socket, so the wiring exchange device is omitted or It is not possible to install electronic components in the position of the wiring exchange device, and the circuit cannot function unless electronic components are installed in all the sockets. Also, for example, PL
When configuring a one-board computer using D,
As shown in Figure 8, if it is a small general-purpose IC, the PL will be small.
D14A is required, and large general-purpose ICs and small PLDs
If it is a combination of I/i and A, it is a large PL D 1
There are cases where you want to mount and wire PLDs of various sizes on the same board and use them effectively, such as when 4.8 is required.
With the conventional technology, it is not possible to mount electronic circuit components of different sizes, such as CPUs and large-scale PLDs, that do not fit into normal sockets. Furthermore, the position of the electronic circuit components and the position of the wiring exchange device are each fixed, making it impossible to change their positions. Therefore, it is not possible to realize an arbitrary circuit. Ta. Furthermore, in the above-mentioned Japanese Patent Application No. 1-142382, a board adapter is used which has a wiring determining means for determining and overturning the wiring connection between the adapter pins of a photo adapter inserted into a Mogicor socket, as described above. This allows wiring connections to be easily determined or changed at any position on the board. However, there is a problem in that a space is required for arranging a board adapter that is mounted on the configurable electronic circuit board 85 and has wiring determining means for determining wiring connections between the adapter pins. be. When placed on the configurable electronic circuit board J3, this installation space requires a square space of the minimum unit of standardized size and number of bins. Furthermore, on such a configurable electronic circuit board, it is necessary to consider the placement position of an adapter that has wiring determination means for determining wiring connections between adapter pins, which reduces the degree of freedom in component placement. There is also the problem. The present invention has been made to solve the above-mentioned conventional problems, and it is possible to increase the degree of freedom in arranging electronic circuit components of any size on a board, and to improve the degree of integration of the board on which it is mounted. The first object of the present invention is to provide a configurable electronic circuit board adapter. In addition to the first object, the present invention also has a second object of providing an adapter for a configurable electronic circuit board that can instantly change the wiring state or change to a wiring determining means with different characteristics.

Note that after the configuration is completed, the wiring determining means 20
Since no logical operations are performed, there is very little heat generation. Therefore, there are almost no thermal problems. However, if the heat generated by the wiring determining means 20 becomes a problem, a space may be provided between the lower surface of the mounted electronic circuit component 30A and the upper surface of the wiring determining means 20 to dissipate heat through ventilation. , a heat radiation means such as a radiation fin may be provided on the board adapter 40A. FIG. 4(A) is a top view of a second embodiment to which the present invention is applied. Further, FIG. 4(B) is a side view of the second embodiment of the present invention. In these FIGS. 4 (Δ) and (B), the reference numeral 40B is a board adapter, and the reference numeral 12.14 is the same as the one with the same reference numeral in the first embodiment of the present invention shown in FIG.

The arrows 30130Δ and insertion A are the same as those with the same reference numerals in FIG. However, in FIG. 5, the wiring determining means 20
is removable and replaceable. The insertion arrow B in FIG. 5 indicates the insertion and mounting of the wiring determining means 20 into the board adapter 40B. Further, the state in which the wiring determining means 20 is attached to the board adapter 40B is indicated by the broken line 2OA in FIG. When this wiring determining means 20 is mounted on the board adapter 40B, a plurality of wiring determining means bins 24 attached to this wiring determining means 20 are connected to a plurality of wiring determining means bins 24 attached on the board adapter 40B. It is inserted into the wiring determining means socket 22, thereby connecting the wiring determining means 20. By making the wiring determining means 20 removable and replaceable in this manner, the wiring state can be immediately changed by, for example, replacing the wiring determining means 20 with a wiring determining means 20 in which a different wiring state is defined. Further, this wiring determining means 20 can be used as a wiring determining means 20 that can be connected and programmed any number of times, a wiring determining means 20 that can be connected and programmed only once, or a wiring determining means that has a short delay time (using metal wiring, etc.). 20 can be exchanged instantly.

In FIG. 7, on the configurable electronic circuit board 1, there are regularly a large number of module sockets each having a standardized size and the minimum number of pins (the ones shown in FIG. 7 are a total of 6× 6-36 pieces) arranged side by side. Further, on this configurable electronic circuit board 1, a board adapter 40A of the first embodiment of the present invention, a board adapter 40B of the second embodiment of the present invention, and a third board adapter of the present invention are mounted on the configurable electronic circuit board 1 via module sockets. The board adapter 40C of the embodiment, the electronic circuit component adapter 40D of the earlier application, and the bypass adapter 4.0E of the earlier application are inserted and mounted, and the process proceeds to G.

Further, in the fourth row from the bottom, an electronic circuit component adapter 40D into which the CPU 10 is inserted is mounted. Further, the board adapter 40A and the two electronic circuit component adapters 40D of the first embodiment of the present invention on the left end row of the combination grapple electronic circuit board 1 are connected to the I/○ port 52.

4. This is to connect A and the large PLD 14B. In this bypass adapter 40E, since the wiring connection is determined by the metal wiring 26, the signal is not delayed. The second row from the bottom of this configurable electronic circuit board 1 is mostly newly designed circuits. For this reason, board adapters 40Δ, 40B having wiring determining means are used in this portion. That is, the board adapter 40A of the first embodiment is used at the left end of the second row from the bottom, making it possible to change the wiring determination. Furthermore, it is expected that the wiring relationship for the second line from the left end of this second row will be determined in the relatively near future. Therefore, in this part, initially, the wiring determining means 20, which can be connected and programmed any number of times, is connected to the board adapter 4. The board adapter 40B of the second embodiment is used by inserting it into the adapter socket 44 of the OB, and in the future it will be replaced with a one-time programmable wiring determining means 20. The third line from the bottom of configurable electronic circuit board 1 is
The circuit is designed in the past and has a proven track record. Therefore, the possibility of changing the wiring connections in this part is extremely small. Therefore, in this part, the electronic circuit component adapter/1. which does not have the wiring determination means 20. OD is used. 2nd and 3rd rows from the bottom of Configurable Electronic Circuit Board 1
The portion of the dog PLD 14B that straddles the rows also includes a newly designed circuit whose wiring connection relationship is scheduled to be changed. Furthermore, since the signal transmission delay is a problem, the board adapter 4. of the second embodiment is designed so that it can be replaced with a wiring determining means 20 that can be connected only once in the future.
I am using OB. Although the CPU IOC is mounted on the fourth row from the bottom of the configurable electronic circuit board 1, the possibility of wiring changes in this part is extremely low. Therefore, the electronic circuit component adapter 4.0D, which does not have the wiring determining means 20, is used in this part. As explained above, according to these embodiments, the board adapter of the present invention is mixed together with the board adapter of Japanese Patent Application No. 1142382 filed by the present inventors on the configurable electronic circuit board as described above. It can be used as Furthermore, the entire actual circuit can be quickly configured by using these board adapters according to the requirements for design completeness and high speed signal transmission. Further, it is also possible to partially verify the high-speed processing part first while it is connected to the entire circuit. Further, it is possible to perform from low-speed clock verification to high-speed clock verification at the clock speed actually used on the same board (by replacing the board adapter or switching the connection changeover switch). Further, it has excellent effects such as being able to reduce the board size of the configurable electronic circuit board compared to the case where only the board adapter of the earlier application (Japanese Patent Application No. 1-142382) is used.
