    • A logic simulator for simulating operation of a logic circuit is provided with gates divisible into successive levels according to a connection pattern between the gates. A pattern memory (16) memorizes the connection pattern as a bit sequence representative of direct connections between each gate of each level to the gates of a preceding level. A function memory (17) memorizes logic functions of the respective gates. Responsive to input logic states of each level, the bit sequence for the gates of the level under consideration, and the logic functions of the respective gates of that level, a calculator (25) calculates output logic states of that level as input logic states of a succeeding level successively for the gates of the level in question. For a higher speed of simulation, the logic circuitry may be divided into a predetermined number of gate groups, each consisting of gates of the successive levels. Each of the pattern and the function memories is divided into parts for the respective gate groups. In order to make the logic simulator have a further reduced memory capacity, the gates of each preceding level may be classified into gate blocks. A block specifier is additionally used. Under the circumstances, it is sufficient that each bit sequence should represent direct connections to the gate blocks. The calculator is supplied with the output logic states of each gate block.
    • 用于模拟逻辑电路的操作的逻辑模拟器被提供有根据门之间的连接模式可分为连续级的门。 模式存储器(16)将连接模式存储为表示每个级别的每个门到前一级的门之间的直接连接的比特序列。 功能存储器(17)存储各个门的逻辑功能。 响应于每个级别的输入逻辑状态,所考虑的电平的门的位序列和该电平的相应门的逻辑功能,计算器(25)计算该电平的输出逻辑状态作为输入逻辑状态 先后成为有关级别的大门的后续级别。 为了更高的仿真速度,逻辑电路可以被划分成预定数量的栅极组,每个栅极组由连续电平的栅极组成。 图案和功能存储器中的每一个被分成用于各个门组的部件。 为了使逻辑模拟器具有进一步降低的存储容量,每个前一级的门可以分为门块。 另外使用块说明符。 在这种情况下,每个位序列应该表示到门块的直接连接就足够了。 计算器提供每个门控块的输出逻辑状态。
