Abstract
PURPOSE: To obtain simply and surely error-on signals to detect and display abnormal waveforms by providing an ECC check circuit, etc., in a logic scope and using ECC for normal waveforms to check waveforms.
CONSTITUTION: When inspection signal S1 of an inspected circuit is a normal waveform, the ECC part is written in ECC storage register 9. Next, inspection signals S1 are inputted to sequential waveform displaying memory 7 and ECC check circuit 8 line by line. ECC check circuit 8 uses ECC from ECC part storage register 9 to check inspection signals S1; and if an error is detected in inspection signals S1 as the result, error-on signal S2 and inspection signal S1 are inputted to ECC check control.ECC analysis control circuit 10. Then, control circuit 10 stops the update of memory 7 and displays memory contents at this time on display screen 14.
