    • A logic simulation system for simulating a quality of logic description of a tested electric circuit includes a storage for storing execution results of logic simulation which was conducted for the electric circuit in the past and for which operations of the circuit have been confirmed, logic description to be tested for the electric circuit, and test data of the logic description to be tested. Logic simulation is conducted according to the test data and the logic description to be tested. Results of the logic simulation are compared with the past logic simulation results of operation by correcting time values according to a predetermined rule so as to simulate quality of the logic description, thereby outputting quality of the logic description in a visible form.
    • 用于模拟测试电路的逻辑描述的质量的逻辑模拟系统包括用于存储对过去的电路进行的逻辑模拟的执行结果的存储器,并且已经确认了电路的操作,逻辑描述 对电路进行测试,并对要测试的逻辑描述进行测试数据。 根据测试数据和要测试的逻辑描述进行逻辑仿真。 通过根据预定规则校正时间值,将逻辑仿真结果与过去的逻辑仿真结果进行比较,以模拟逻辑描述的质量,从而以可见的形式输出逻辑描述的质量。

    • The electronic circuits of a large-scale ASIC or logic device are assigned to a plurality of programmable chips with logic block division that enables the finished circuits to operate at appropriate timings. A logic division processing unit divides the electronic circuits into a plurality of groups for automatic assignment to a plurality of programmable chips. A checking unit determines whether the designated logic blocks are accommodated in one programmable chip, and a division processing unit determines which logic blocks are to be assigned and the order of assignment priorities when the designated logic blocks are not all accommodated in the same programmable chip.
    • 大规模ASIC或逻辑器件的电子电路被分配给具有逻辑块划分的多个可编程芯片,使得成品电路能够在适当的定时运行。 逻辑分割处理单元将电子电路分为多个组,用于自动分配给多个可编程芯片。 检查单元确定指定的逻辑块是否被容纳在一个可编程芯片中,并且分割处理单元确定哪个逻辑块将被分配,并且当指定的逻辑块不全部被容纳在相同的可编程芯片中时,分配优先级的顺序。
