Abstract
In response to a design request, fault detection strategy optimizing means selects RT-VCs and a fault detection method from a VCDB. The design request includes: requirements for a system LSI (e.g., area, number of pins, test time and information about the weights of prioritized constraints); and VC information. The fault detection strategy optimizing means performs computations for optimization in view of various parameters, thereby specifying a best fault detection strategy and a method of constructing a single-chip fault detection controller. On the VCDB, multiple VCs associated with the same function and mutually different test techniques are stored. By weighting the parameters affecting a test cost in accordance with a user defined priority order, a test technique of the type minimizing the total test cost can be selected from the VCDB.
