Peter Chochula CERN-ALICE / Dpt. Of Nucl. Physics MFF UK Bratislava Interfacing with IC tester  Software interface : –Screens will be used to debug the chips –TestView based programs will be used to characterize the chips (complicated measurements requiring multiple runs and data evaluation)  Possible test enhancements: –Connection Wafer Prober - IC tester exists, but was not yet tested –need to synchronize with a PC controlling the prober (using LabView and BusLab)  There is no JTAG controller attached to the tester. To overcome this limitation one can:  Emulate JTAG controller with the tester: Use Verilog Simulation or an vector generator to prepare patterns which will be scanned to the chip. Reloading of patterns might be slow!  Use external PC equipped with F100 board. This task involves synchronisation of PC and SUN over TCPIP, which should be fast. However there is a risk of inducing new problems while using additional hardware and software
