1 Introduction The SMT348 is an FPGA TIM module designed to be integrated in modular systems. It is designed to connect to the huge range of other TIM modules and carriers developed by Sundance. Sundance modular solutions provide flexible and upgradeable systems. The SMT348 is a TIM module aimed at completing the range of Sundance Virtex4 modules like SMT368, SMT362, SMT339. It provides a communications platform between an XC4VSX55 or XC4VLX160 FPGA and • 4 banks of QDR2 SRAM at a fre

JTAG 4 Functional Description This module conforms to the TIM standard (Texas Instrument Module, See TI TIM specification & user’s guide) for single width modules. It sits on a carrier board. The carrier board provides power (5V, 3.3V, +/-12V), ground, communication links (Comport links) between all the modules fitted and a pathway to the host, for a non stand-alone system. The SMT348 requires a 3.3V power supply (as present on all Sundance TIM carrier boards), which must be provided

4.2.5 FPGA Configuration schemes Different schemes are available to provide maximum flexibility in systems where the SMT348 is involved: The FPGA configuration bitstream source is • On Comport 3: The CPLD is connected to the Comport 3 link of the SMT348 TIM connector. (See block1). A switch is used to select Comport 3 as the link that will be used to receive the bitstream. The CPLD allows for FPGA configuration in slave SelectMAP mode. • Using the on-board Flash memory. The CPLD monito

4.2.6 FPGA Reset Scheme The CPLD is connected to a TIM global Reset signal provided to the SMT348 via its primary TIM connector pin 30. (See TI TIM specification & User’s guide). This signal goes to the CPLD and the FPGA. Nevertheless as a general rule for good practice, the FPGA should not use this reset but should use the reset signal generated by the CPLD. The CPLD provides another signal called FPGAResetn that offers a better Reset control over the FPGA. At power up or on reception

Figure 2: CPLD state machine 4.2.7 FPGA Bitstream formatting If you generated you FPGA bitstream using Diamond FPGA, you do not need any other handling. The .app file created can be used as is to configure the FPGA. If you used Xilinx ISE and created a .bit file, you need to use the Sundance executable “Getrawdata.exe” provided for free in the SMT6001 package. Please read the SMT6001 help file at chapter: “Saving FPGA configuration data to file”. The

4.2.8 QDR2 SRAM Up to 4 Mbytes of QDR2 SRAM per bank. The memory is available as 4 independent banks. The QDR2 memory runs at 250MHz. Each bank is fully independent with separate address, control and data busses and arranged as follows: Figure 3: FPGA connections to Bank1 of QDRII The devices used are Samsung K7R321884M. Alternative part numbers, fully compatible can be fitted depending on availability at time of order. User Manual SMT348 Page 14 of 29 Last Edit

4.2.9 Sundance High speed Bus 2 x 60 pin connectors provide 80 IO connections between the FPGA and the outside word. They allow interfacing to other Sundance modules providing that you implement an SHB interface in the FPGA. (See 2.1) The SHB interface is available in Sundance SMT6500 support package. Either two 16-bit, or 1 32-bit interface can be implemented per connector. They allow interfacing to the outside world by implementing your own interface in the FPGA. The FPGA IO banks hosti

4.2.11 TIM Connectors TIM connectors provide 4 communication links (Comports) and a Global Bus to the FPGA. The comports which are available on the SMT348 are CP0, CP1, CP3, and CP4. They allow interfacing to Sundance TIM modules or to a Host PC providing that you implement a Comport Interface inside the FPGA. (See 2.1) The Comport interface is available in Sundance SMT6500 support package. The FPGA io banks hosting the Comport signals are powered using Vcco = 3.3v. The TIM connectors als

4.2.13 Clocking scheme The SMT348 module contains a 50MHz LVTTL clock, a 200MHz clock, and a connector for an external LVTTL clock input/output. 50 MHz LVTTL oscillator: Main system clock. Clocks the CPLD and the FPGA. Can be input in a DCM. 200MHz LVTTL oscillator: QDRII clock. Can also be used as a main FPGA clock. Can be input in a DCM. An external clock input is provided to the Virtex 4 FPGA via an MMCX connector. This connector is NOT fitted by default or if a mezzanine is require
