MDGG - 16 multi functional VME Logic Module

The MDGG-16 is a single wide 6U VME multi functional FPGA based delay logic and timing module which provides often needed functions as gate generator & pulse generator, logic fan in - fan out, coincidence register and scaler / pre-scaler. The module has 16 LVDS/ECL inputs and 16 ECL outputs on pin headers and 2 NIM inputs as well as 4 NIM outputs (Lemo), which are free configurable in regards to their functionality.

The MDGG-16 is based on a XC3S500E FPGA with 36kB of block RAM. One FPGA configuration file can be stored in the on-board flash memory  from which the FPGA can boot at power-on. The flash memory can be reprogrammed via VME for firmware upgrades. The required logic functionality can be programmed in a easy way by the writing configuration data into MDGG-16 registers via VME D32 A24 "write" commands.

MDGG-16 can be readily customized within the constraints set by the hardware resources. It may be considered an 18-input/20-output/7-diagnostic LED universal logical module for which the user can develop his own firmware using the free XILINX WebPack software.

Main features

  • FPGA based VME logic module
