Abstract
A stage tracer comprising a plurality of tracing units which are physically independent of one another and each of which includes a memory unit and the associated read/write control logic unit, and a common control unit provided physically independent of and electrically connected with the tracing units, to supply desired control signals to the respective read/write control logic units. In each tracing unit, under the control of the common control unit, the read/write control logic unit causes the signals to be observed to be written in the memory unit and also causes the content of the memory unit to be read out onto the data bus common with all the tracing units.
