Test application at reduced power supply voltage (or VLV testing) is a cost-effective way to increase the defect coverage of a test set. Resistive short defects are a major contributor to this coverage increase. Using a probabilistic model of these defects, we quantify the coverage impact of VLV testing for different voltages. When considering the coverage(More)
We present a simulator for resistive bridging and stuck-at faults. In contrast to earlier work, it is based on electrical equations rather than table look-up, thus exposing more flexibility. For the first time, simulation of sequential circuits is dealt with; reciprocal action of fault effects in current time frame and earlier time frames is elaborated on(More)
This paper proposes a methodology for testing the configurable logic of RAM-based FPGAs taking into account the configurability of such flexible devices. The methodology is illustrated using the XILINX 4000 family. On this example of FPGA, we obtain only 8 basic Test Configurations to fully test the whole matrix of CLBs. In the proposed Test Configurations,(More)
The use of the Oscillation Test Strategy to test Configurable Analog Blocks of Field Programmable Analog Arrays (FPAAs) has been proposed previously, solving the complex problem of test stimuli generation. An improvement to that technique is presented in this paper, using the resources of the FPAA to build an Output Response Analyzer. This new approach(More)
