Abstract

PURPOSE: To obtain a LSI element simulation circuit which has several externally- controllable connection pins, allows the same logic as that of an external controller to be programmed, and provides different LSI element simulation only by changing programs.
CONSTITUTION: This circuit consists of connection pins 4a to 4c for a decision on whether these should be used as input pins or output pins, serial shift register 1 as a 1st memory method, inverters 21aW21c which determine independently 4aW4c, serial shift register 7 as a 2nd memory method, register 6 as a 3rd method, AND gate 2aW2c which output the content of a corresponding bit of register 6 to a connection pin of 4aW4c regarded as an output pin by the determination, register 8 as a 4th memory method, and selector 12 which output bit series data read out from register 8 to pin 5a. Then, LSI circuit 14 of this constitution can eliminate troubles and faults that a similar circuit of individual component constitution has.
