PURPOSE:To obtain displayed information accurately in time series and shorten a logic analysis time by providing a setter capable of setting and inputting a display area and displaying only the display area designated with the setter by a different system from other display areas. CONSTITUTION:Address information obtained through an input circuit 1 is sampled successively and stored in memory 2. The stored address data is read out by a control circuit 3 in the storage order, sent to a display device 4 after necessary processing for mapping display is carried out, and mapped and displayed on a display screen. Simultaneously, the circuit 3 outputs data from the starting point of the sample memory to a point designated with the setter 5 with different high brightness from other data, and their values are received from the setter 5 through an interface 6. Thus, only; the display area designated with the setter 5 is displayed with the different high brightness from other display areas. The displayed information is therefore traced easily in time series and the logic analysis time is shortened. |
