On-board Peripherals

System Controller CPLD

The System Controller CPLD

Table 9: I²C-interface between SC CPLD and DDR3 SDRAM memory.

System Controller CPLD

The System Controller CPLD is the central system management unit that provides numerous interfaces between the on-board peripherals and to the FPGA module. The signals routed to the CPLD will be linked by the logic implemented in the CPLD firmware, which generates output signals to control the system, the on-board peripherals and the interfaces. So some interfaces between the on-board peripherals and to the FPGA module are by-passed, forwarded and controlled by the System Controller CPLD.

Other tasks of the System Controller CPLD are the monitoring of the power-on sequence, the proper programing of the FPGA module and to display its programming state.

Following table describes the interfaces and functionalities of the System Controller CPLD , which are not described elsewhere in this TRM:

SO-DIMM Socket for DDR3 SDRAM

The TEC0330 board supports additional DDR3 SO-DIMM via 204-pin socket U2. The DDR3 memory interface is routed to the FPGA banks 34, 35 and 36.

The reference clock signal for the DDR3 interface is generated by the quad programmable clock generator U13 and is applied to the FPGA bank 35.

There is also a I²C interface between the System Controller CPLD and the DDR3 SDRAM memory:

Quad SPI Flash Memory

An 256 Mbit (32 MByte) Quad SPI Flash Memory (Micron N25Q256A, U12) is provided for FPGA configuration file storage. After configuration process completes the remaining free memory can be used for application data storage. All four SPI data lines are connected to the FPGA allowing x1, x2 or x4 data bus widths to be used. The maximum data transfer rate depends on the bus width and clock frequency. The memory can be accessed indirectly by the FPGA JTAG port (J9) by implementing the functional logic for this purpose inside the FPGA.

Clock sources

The TEC0330 FPGA board has a sophisticated clock generation and conditioning system to meet the requirements of the Xilinx Virtex-7 GTH units with data transmission rates up to 13.1 Gb/s.

Clock sources

List of on-board and external reference clock signals of the TE0330 board:

Table 1215: Clock generator sources overview.

...

There is a Silicon Labs I²C programmable quad clock generator Si5338A (U13) on-board. It's output frequencies can be programmed by using the I²C-bus with address 0x70are programmable via FPGA I²C interface using slave device address 0x70 (corresponding I²C logic has to be implemented in FPGA design).

A 25 MHz (U14) oscillator is connected to pin 3 (IN3) and is used to generate the output clocks.Once running, the frequency and other parameters can be changed by programming the device using the I²C bus connected between the FPGA (master) and clock generator (slave). Logic needs to be generated inside the FPGA module to utilize I²C-bus correctly.

Power-On Sequence

The on-board voltages of the TEC0330 FPGA board will be are powered up in order of a determined predefined sequence after the external voltages 12V on connector J5 and 3V3PCI on connector J1 are become available.

Core voltages and main supply voltages have to reach stable state and their "Power Good" - signals have to be asserted before other voltages like PL bank's I/O voltages can be powered up.
