A good example of a mixed analog-digital FPGA application is the embedded particle tracking silicon microscope, developed originally for investigations in radiation biology [1], but then used extensively for the characterization of radiation effects in silicon strip sensors [2]. It makes use of many FPGA resources, such as the digital clock management (DCM) block, random access memory (RAM), ‹rst-in-‹rst-out (FIFO) block, and so on. It was a fertile ground for several student theses at the University of California-Santa Cruz [3-5].
