(target) FPGA. With the release of 7series FPGA boards, Alpha Data has introduced a new build option to allow the mezzanine card to be assembled without the bridge to reduce power and cost.
The power dissipation of the board is highly dependent on the Target FPGA application. A power estimator spreadsheet is available on request from Alpha Data. This should be used in conjunction with Xilinx power estimation tools to determine the exact current requirements for each power rail.

V2.1 - 6th January 2016 metalwork for conduction cooled applications. For more details on heatsinks supplied with Alpha Data boards, please view AD-AN-0018 ADM-XRC Cooling Solutions. The board features system monitoring that measures the board and FPGA temperature. It also includes a self-protection mechanism that will clear the target FPGA configuration if an over-temperature condition is detected.
Note: The ADA-VPX3-7V1 is comprised of an ADM-XRC-7V1 XMC card mounted to an ADC-VPX3-XMC VPX carrier specifically designed to host Alpha Data XMCs. All reference to "XMC" refer to the ADM-XRC-7V1, while all references to "Carrier" refer to the ADC-VPX3-XMC.

ADA-VPX3-7V1 User Manual V2.1 - 6th January 2016 3.2 VPX P0 Interface 3.2.1 MVMRO Non-Volatile Memory Read Only. This signal is an input from the system. When asserted (high), all writes to non-volatile memories are inhibited. This is indicated by the Amber LED, XMC-D7.
ADA-VPX3-7V1 User Manual V2.1 - 6th January 2016 3.3 JTAG Interface 3.3.1 On-board Interface A JTAG boundary scan chain is connected to header XMC-J1. This allows the connection of the Xilinx JTAG cable for FPGA debug using the Xilinx ChipScope tools.
4 user-programmable clocks. These clocks can be combined with the FPGA's internal PLLs to suit a wide variety of communication protocols. A complete overview of the clock routing on the ADA-VPX3-7V1 is given in Figure Clocks. A description of each clock follows.
MGT signal inputs. Most needed reference clocks can be generated through the User Programmable clocking options. If it is a requirement that this differential pair be utilized as a clock signal to an MGT bank, a resistor fit option is available. Please contact Alpha Data for detials.

There are two programable clock sources that are forwarded throughout the FPGA. These clocks are programmable through the Alpha Data ADM-XRC Gen 3 SDK. LCLK is generated in the Bridge FPGA by the the Alpha Data ADB3 driver and offers a less accurate frequency resolution, but with a wider programmable frequency range.
ADA-VPX3-7V1 User Manual V2.1 - 6th January 2016 3.4.8 XRM LVDS Clock (XRM_LVDS_CLK) The clock "XRM_LVDS_CLK" is a differential clock signal using LVDS levels. The clock is provided by the target FPGA and connected to an XRM module through the XRM connector, CN1, at pins 113 & 115.
FLPAGE and FLDATA registers in the Bridge FPGA. The region of memory between addresses 0x11000000 and 0x11FFFFF is allocated for custom data to be stored by the ADA-VPX3-7V1 user. Utilities for erasing, programming and verification of the flash memory are provided in the ADMXRC SDK.
ADA-VPX3-7V1 User Manual V2.1 - 6th January 2016 3.6 Configuration 3.6.1 Power-Up Sequence If valid data is stored in the flash memory, the bridge will automatically configure the Target FPGA at power-up. This sequence can be inhibited by turning the Flash Boot Inhibit (FBI) switch, SW1-5 to ON. (See Table XMC SW1 Definitions).
V2.1 - 6th January 2016 3.7 Health Monitoring The ADA-VPX3-7V1 has the ability to monitor temperature and voltage to maintain a check on the operation of the board. The monitoring is implemented using the ATMEGA128 microcontroller. Control algorithms within the microcontroller automatically check line voltages and on board temperaturs and shares the information with blockram in the Bridge FPGA.
ADA-VPX3-7V1 User Manual V2.1 - 6th January 2016 3.7.1 Automatic Temperature Monitoring At power-up, the control logic sets the temperature limits and resets the LM87's over-temperature interrupt. The temperature limits are shown in Table Temperature Limits: Target FPGA Bridge FPGA...
ADA-VPX3-7V1 User Manual V2.1 - 6th January 2016 3.8 Local Bus A Multiplexed Packet Transport Link (MPTL) connects the Bridge and Target FPGAs. It is capable of transferring data at up to 2GB/s simultaneously in each direction. The MPTL replaces the parallel local bus used in previous generations of the ADM-XRC series. Details of the link and example designs are given in the Software Development Kit (SDK).
ADA-VPX3-7V1 User Manual V2.1 - 6th January 2016 devices (Micron MT41J64M16-187E) are fitted as standard to provide 512MB per bank. 4Gb (giving 1GB per bank) are available as an ordering option. The memory banks are arranged for compatibility with the Xilinx Memory Interface Generator (MIG).
