PROBLEM TO BE SOLVED: To provide a circuit system, a connection correction method, and a circuit capable of automatically correcting a misconnection between circuits when transmitting multi-bit data in parallel.SOLUTION: A circuit system 100 transmits multi-bit output data signals D[0]-D[3] from a transmission-side LSI 1 to a receiving-side LSI 2 in parallel. The LSI 1 has a pattern generation unit 11 for generating test signals T[0]-T[3], an output selection unit 12 for selecting one of the test signals and internal output data signals, and output pins P-Pfor outputting the signal selected by the output selection unit 12. The LSI 2 has input pins P-Pconnected to the output pins P-P, a pattern detection unit 21 for specifying an order of bits of the input pins P-Pon the basis of the test signals, and an input selection unit 22 for selecting a signal from the input pins P-Pin accordance with the specified order of bits.SELECTED DRAWING: Figure 1 |
