MDGG - 8 multi functional VME Logic Module
The MDGG-8 is a single wide 6U VME multi functional FPGA based delay logic and timing module which provides often needed functions as gate, delay & pulse generator, logic fan in - fan out, coincidence register and scaler / pre-scaler. The module has 8 inputs and 8 outputs with NIM levels, which are free configurable in regards to their used functionality.
The MDGG-8 is based on a XC3S400 FPGA with 36kB of block RAM. Two FPGA configuration files can be stored in the on-board flash memory from which the FPGA can boot at power-on (selection by a jumper). The flash memory can be reprogrammed via VME for firmware upgrades.
MDGG-8 can be readily customized within the constraints set by the hardware resources. It may be considered an 9-input/8-output/12-diagnostic LED universal logical module for which the user can develop his own firmware using the free XILINX WebPack software.
