While technology advances, CPUs are developed with a multicore approach in mind. General-purpose computing on graphic processing units (GPGPU) is becoming a viable approach for massive parallelization approaches, exploiting a higher number of cores and the many-core approach. The work of the thesis regards two distinct problems: a flying-probes test optimization algorithm and a VCD file reader which exploits the power of multithreading on the CPU, while its work exploiting GPU capabilities is under development. 1) Testing on printed circuit boards (PCBs) can be achieved by using flying-probes instrumentation. While the instrumentation has constraints, it is imperative to be able to optimize tests in such a way that their duration is minimized, by moving the probes as least as possible.
