在我做DMA过程中,我增加了一个SRAM_16Bits_512K(sram_0),两个on_chip memory(ram)(一个做为dma的write_buffer,一个做为read_buffer),但在编译的时候出现了下面两个错误:

Error: Can't open AHDL Include File memmodes.inc
Error: Node instance "sram" instantiates undefined entity "altdpram"

在c:/altera/quartus51/libraries/megafunctions/altdpram.tdf中第一句是:

INCLUDE "memmodes.inc";   % Constants defining RAM mode flags %

在c:/altera/quartus51/libraries/megafunctions/lpm_ram_dp.tdf程序如下

INCLUDE "altdpram.inc";
INCLUDE "lpm_mux.inc";
INCLUDE "lpm_decode.inc";

CONSTANT NO_FILE = "UNUSED";

请各位牛人帮忙看一下是哪里出了问题啊!
