Logic simulation system using actual circuit in combination

TL;DR: In this article, the input conditions of an external logic circuit whose operation conditions are already known through an interface are used to reduce the man power and time necessary for the constitution of a virtual logic circuit for simulation of a synthetic logic circuit.

Abstract: PURPOSE:To reduce and shorten the man power and time necessary for the constitution of a virtual logic circuit for the simulation of a synthetic logic circuit by setting the input conditions of an optional external logic circuit whose operation conditions are already known through an interface. CONSTITUTION:A gate, etc., are constituted as the virtual logic circuits on an electronic computer 6 and simulate operation. An LSI7, on the other hand, is a logic circuit whose operation conditions are already known and uses a real thing. Operation results of the gate, etc., are set to the input terminal of the LSI7 through an interface part 8 and the state of variation in the output of the LSI7 is read to simulate the operation of the gate, etc. again. Thus, the software simulation is performed as to the gates, etc., from the output to the input of the LSI7 for every step in a general way, so the man power and computation time necessary for the simulation are reduced and shortened greatly.
