<P>PROBLEM TO BE SOLVED: To provide a development support device solving a basic problem wherein timestamp information is restricted by bit width of a memory storing the timestamp information, and a problem of restriction from trace memory capacity. <P>SOLUTION: This development support device has: a CPU supplying an address to an evaluated circuit; a comparator comparing the address outputted from the CPU and a previously designated address in time of software execution of the CPU, and outputting an accordance signal when both the addresses accord; a first storage part storing trace information when the accordance signal is outputted from the comparator; a first counter counting a clock signal to generate the timestamp information; a second storage part storing the timestamp information generated by the first counter when the accordance signal is outputted from the comparator; and a second counter counted up when a carry signal is outputted from the first counter. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
