[Other resource] leon3-altera-ep2s60-ddr

Description: This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct delay models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec

[VHDL-FPGA-Verilog] sdram

Description: sdram控制器 这里考虑将SDRAM控制器结合目前项目开展来做相应的模块，而不做SDRAM通用控制器，这样也是考虑了FPGA的器件资源而采取的措施。同时编写的逻辑简单，没有多余的逻辑资源有利于提高控制器的速度，满足最后的设计要求。-SDRAM controller here consider SDRAM controller current projects do the corresponding module, but not so common SDRAM controller, as well as consider the FPGA device resources and the measures taken. While the preparation of simple logic, the logic is no spare resources to improve the speed controller to meet the final design requirements.
