Introduction

The LogicBox is an electronic data adquisition und control system based on FPGA. It was developed at the "Physikalisches Institut Universität Heidelberg" to process and control typical Nuclear Physics experiments for scientific and educational purposes only. The LogicBox consist of a FPGA main board with USB 1.1, USB-2 or VME interface and up to 8 I/O Sub-modules or extension cards with the necessary analogue or digital electronic to control or measure the desired signals. A firmware programmed into the FPGA as well as interface software allow the user to build fast and with flexibility a custom application. The system can be found in 3 different chassis:

Base cards
Format	Product id
Compact	DL701
NIM	DL706 or DL709
VME	DL710

The provided software is implemented in LabVIEW, This software library is called "LogicPool", and content a lot of soft-modules frequently used in the Nuclear Physics. The user can interconnect these modules, as he likes to create the desired setup. We are working to improve the system with new sub-modules/extensions boards and faster interface to be able to process more data. At this moment we have developed 30 sub-modules as multiple coincidence, fan in / fan out, splitter, logic, discriminator, ADC, TDC, etc., The logicBox is the ideal replacement of the typical NIM racks with several non programmable NIM modules frequently used in the Nuclear Physics, which implement trigger Logic, rate meter, Time to digital converter, acquisition, etc.
