    • An electronic circuit device has a high-density mount board (2), on which are disposed a microcomputer (3) and random access memory (7) which are connected to each other through an exclusive memory bus (12) for high-speed data transfer, a programmable device (8) which is a variable logic circuit represented by FPGA, and an electrically-rewritable nonvolatile memory (16) which can store the operation program of the microcomputer. The high-density mount board has external mounting pins on the bottom surface so that it can be mounted on a mother board in the same manner as a system on-chip multi-chip module. With an intended logic function being set on the programmable device, a hardware-based function to be realized by the electronic circuit device can be simulated. With an operation program being written to the nonvolatile memory, a software-based function to be realized can be simulated. Consequently, the device facilitates the debugging at early stages of system development, configures a prototype system, and contributes to the time reduction throughout the system development, prototype fabrication and large-scale production.
    • 电子电路装置具有高密度安装板(2),微型计算机(3)和随机存取存储器(7)设置在其上,通过用于高速数据的专用存储器总线(12)彼此连接 传输,由FPGA表示的可变逻辑电路的可编程器件(8)和可存储微型计算机的操作程序的电可重写非易失性存储器(16)。 高密度安装板在底面上具有外部安装销,使其可以以与系统片上多芯片模块相同的方式安装在母板上。 通过在可编程器件上设置预期的逻辑功能,可以模拟由电子电路器件实现的基于硬件的功能。 通过将操作程序写入非易失性存储器,可以模拟要实现的基于软件的功能。 因此,该设备便于系统开发初期的调试,配置原型系统,有助于整个系统开发,原型制作和大规模生产的时间缩短。
