VHDL实现的读取和写入SDRAM的程序代码，学习的人可以参考下

Sample behavioral waveforms for design file sin_rom.vThe following waveforms show the behavior of altsyncram megafunction for the chosen set of parameters in design sin_rom.v. For the purpose of this simulation, the contents of the memory at the start of the sample waveforms is assumed to be ( 3F0, 3F1, 3F2, 3F3, ...). The design sin_rom.v has one read port. The read port has 1024 words of 10 bits each. The output of the read port is unregistered. Fig. 1 : Wave showing read operation. The above waveform shows the behavior of the design under normal read conditions. The read happens at the rising edge of the enabled clock cycle. The output from the RAM is undefined until
