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)
In this work a strategy for testing analog networks, known as Transient Response Analysis Method, is applied to test the Configurable Analog Blocks (CABs) of Field Programmable Analog Arrays (FPAAs). In this method the Circuit Under Test (CUT) is programmed to implement first and second order blocks and the transient response of these blocks to known input(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)
Testing a secure system is often considered as a severe bottleneck. While testability requires to an increase in both observability and controllability, secure chips are designed with the reverse in mind, limiting access to chip content and on-chip controllability functions. As a result, using usual design for testability techniques when designing secure(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)
