Claims

[Claims for Utility Model Registration] A first storage means for capturing and storing a current address value of a program being executed in a computer device to be measured from the computer device to be measured; a second storage means for storing an address value executed in the computer device under test; and a second storage means for storing an address value executed in the computer device under test; addition means for adding a minimum address increment value; first comparison means for comparing the current address value provided from the first storage means with the value provided from the addition means; and the first storage. a second step for comparing the current address value given from the means and the address value one step before given from the second storage means;
A computer program tracing device comprising: comparing means; and determining means for determining whether a branch has been executed in the computer program under test based on the outputs of the first and second comparing means.
