8 1 Overview The Spartan-IIE LC Development Kit provides a complete solution for developing designs and applications based on the Xilinx Spartan-IIE FPGA family. The kit bundles an expandable Spartan-IIE based development board with a power supply, user guide and reference designs. P160 expansion modules available from Memec Design enable further application specific prototyping and testing. Xilinx ISE software and a JTAG cable are available as kit options. The Spartan-IIE LC development board utilizes the 300,000/600,000 gate Xilinx Spartan-IIE device (XC2S300E-6FG456C or XC2S600E -6FG456C) in the 456 fine-pitch ball grid array package. The high gate density and large number of user I/Os allows complete system solutions to be implemented in the low cost FPGA. The development board includes 32M bytes of SDRAM, two clock sources, 82 user I/O header pins via 2 on-board headers, an RS-232 port, a VGA connector, an LCD connector, LED displays, switches and additional user support circuits. The board supports the Memec Design P160 expansion module standard, which allows applicationspecific expansion modules to be easily added. A SystemACE interface on the board gives software designers the ability to run real-time operating systems (RTOS) from removable CompactFlash cards when implementing embedded processor solutions. The Spartan-IIE FPGA family has the advanced features needed to fit the most demanding, high volume applications. The Spartan-IIE LC Development Kit provides an excellent platform to explore these features so that you can quickly and effectively meet your time-to-market requirements. 2 The Spartan-IIE LC Development Board The Spartan-IIE LC development board provides the FPGA, support circuits and the expansion slot for realizing advanced FPGA designs. Figure 1 shows a picture of the board and its features. March 10,

The Spartan-IIE 1.8V Field-Programmable Gate Array family gives users high performance, abundant logic resources, and a rich feature set, all at an exceptionally low price. The seven-member family offers densities ranging from 50,000 to 600,000 system gates supporting 200Mhz designs and beyond. Spartan-IIE devices deliver more gates, I/Os, and features per dollar than other FPGAs by combining advanced process technology with a streamlined architecture based on the proven Virtex -E platform. Features include block RAM (up to 64K bits), distributed RAM (to 98,304 bits), 19 selectable I/O standards, and four DLLs (Delay-Locked Loops). Fast, predictable interconnect means that successive design iterations continue to meet timing requirements. March 10,

11 The Spartan-IIE family is a superior alternative to mask programmed ASICs. The FPGA avoids the initial cost, lengthy development cycles, and inherent risk of conventional ASICs. Also, FPGA programmability permits design upgrades in the field with no hardware replacement necessary (impossible with ASICs). 3.2 SDRAM Memory The Spartan-IIE LC development board provides 32MB of SDRAM memory (Infineon Mobile SDRAM, # HYB25L128160AC-8).

When the RJ45 type cable is connected to the JM1 connector, jumpers must be installed on J2 pins 7-8, 9-10, 11-12, and These jumpers connect the on-board JTAG circuitry to the JTAG chain signals. For this reason, you cannot connect the RJ45 cable and the PC3 or PC4 JTAG cable at the same time. The jumpers on J2 actually prevent this from happening. March 10,

23 3.15 ISP PROM The Spartan-IIE LC development board utilizes the Xilinx XC18V02 or XC18V04 ISP PROM, allowing FPGA designers to quickly download revisions of a design and verify the design changes in order to meet the final system-level design requirements. The XC18V02/04 ISP PROM uses two interfaces to accomplish the configuration of the Spartan-IIE FPGA. The JTAG port on the XC18V02/04 device is used to program the PROM with the design bit file. Once the XC18V02/04 has been programmed, the user can configure the Spartan-IIE device in Master Serial or Master SelectMap mode. The configuration of the Spartan-IIE device is initiated by asserting the PROGn signal. Upon activation of the PROGn signal (by pressing the SW2 switch), the XC18V02/04 device will use its FPGA Configuration Port to configure the Spartan-IIE FPGA.

The SystemACE interface on the Spartan-IIE LC development board gives software designers the ability to run real-time operating systems (RTOS) from removable CompactFlash cards. The following figure shows a high-level block diagram of the Memec Design SystemACE module. For more information, please refer to the Memec Design SystemACE module User s Guide document. March 10,

When the MPU port of the SystemACE controller is used, the Spartan-IIE FPGA and the SystemACE controller must use the same clock source. Hence, jumpers are provided on the Spartan-IIE development board and the SystemACE module to provide the clock input to both devices. Two clocking schemes are provided to ensure full synchronization of the MPU interface and also allow a March 10,

31 4 Design Download The Spartan-IIE LC development board supports multiple methods of configuring the Spartan-IIE FPGA. The JTAG port on the Spartan-IIE LC development board can be used to directly configure the Spartan-IIE FPGA, or to program the on-board XC18V02/04 ISP PROM. Once the ISP PROM is programmed, it can be used to configure the Spartan-IIE FPGA. The Slave Parallel/Slave Serial port on this development board can also be used to configure the Spartan- IIE FPGA. The following figure shows the setup for all Spartan-IIE FPGA configuration modes that are supported on the Spartan-IIE LC development board. Slave Serial/SelectMap JP2 Parallel Port JTAG Cable J2 SPIIE Development Board PC JM1 AC/DC Adapter JP1 Figure 17 Download Setup 4.1 JTAG Interface The J2 JTAG connector on the Spartan-IIE LC development board can be used to configure the Spartan-IIE or to program the on-board XC18V02/04 ISP PROM. The Memec Design JTAG cable is connected to the Spartan-IIE LC development board via J2 at one end and to the PC parallel port at the other end. Note: When using the standard JTAG cable, you will need to connect the JTAG and VCC/GND signals to the top row of pins on J2. When using the low-cost RJ45 cable, you will need to place jumpers on J2 as described in section Configuring the Spartan-IIE FPGA When the JTAG port is used to configure the Spartan-IIE FPGA, the following steps must be taken: Using Table 13 set the Configuration Mode of the Spartan-IIE FPGA to JTAG Mode. Install JP6 jumper in the 1-2 position. Use the Xilinx JTAG programmer (impact) utility to load the design bit file into the Spartan-IIE FPGA. You will need to associate the ISP PROM with either a dummy.mcs March 10,

32 file, or a.bsd file to allow the JTAG programming software to pass data through the ISP PROM Programming the XC18V02/04 ISP PROM When the JTAG port is used to program the ISP PROM, the following steps must be taken: Using Table 13 set the Configuration Mode of the Spartan-IIE FPGA to Master Serial Mode. Install JP6 jumper in the 1-2 position. Use the Xilinx JTAG programmer utility (impact) to load the design mcs file into the ISP PROM. You will need to associate the FPGA with either a dummy.bit file or a.bsd file to allow the JTAG programming software to pass data through the FPGA. Upon programming of the 18V02/04 ISP PROM, the on-board PROGn push button switch (SW2) is used to initiate the Spartan-IIE FPGA configuration. 4.2 Slave Serial Interface In this mode, an external source provides the configuration bit stream and the configuration clock (CCLK) to the Spartan-IIE FPGA. Refer to Table 13 for setting up the Configuration Mode pins. The JP6 jumper must be installed (position 2-3) for this mode of configuration. 4.3 Slave Parallel In this mode, an external source provides the configuration bit stream and the configuration clock (CCLK) to the Spartan-IIE FPGA. Refer to Table 13 for setting up the Configuration Mode pins. The JP6 jumper must be installed (position 2-3) for this mode of configuration. March 10,
