【应用笔记】主动串行存储器接口控制器参考设计(ActiveSerialMemoryInterfaceControllerReferenceDesign)如果你正在使用Altera的StratixII、CycloneII或CycloneFPGA做设计，这个主动串行存储器接口(ASMI)控制器参考设计，在存取Altera的EPCS1、EPCS4、EPCS16和EPCS64等串行配置器件的未使用部分时，是非常有用的。IfyouaredesigningwithAltera®Stratix®II,Cyclone™II,orCycloneFPGAs,theactiveserialmemoryinterface(ASMI)controllerreferencedesignisusefulinaccessingtheunusedportionofAlteraEPCS1,EPCS4,EPCS16,andEPCS64serialconfigurationdevices.TheNios®IIembeddedprocessoralsoprovidesacompletesolutionforthiscapabilitybyusingtheEPCSControllermoduleinSOPCBuilder.ActiveSerialMemoryInterfaceControllerReferenceDesignMarch2005,ver.1.0ApplicationNote379IntroductionIfyouaredesigningwithAlteraStratixII,CycloneII,orCycloneFPGAs,theactiveserialmemoryinterface(ASMI)controllerreferencedesignisusefulinaccessingtheunusedportionofAlteraEPCS1,EPCS4,EPCS16,andEPCS64serialconfigurationdevices.TheNiosIIembeddedprocessoralsoprovidesacompletesolutionforthisca……

在Quartus中直接能过JTAG接口来烧写EPCS系列芯片GaosMake通过JTAG直接下载程序到EPCS系列配置芯片一、电路设置以上图中注意以下点1、VCCIO为nSTATUS,CONF_DONE,nCONFIG所在BANK的电源，VCCA为2.5V（本人使用3.3V也没有问题)2、nCE要直接接地,(7)中所接的25欧电阻要接近配置芯片3、在通过JTAG接口烧写EPCS芯片时，EPCS芯片要进入AS模式，MSEL（3..0)要按白皮书中所说的接，如下图1GaosMake我所用的芯片EP3C25，电压为3.3V，所以我选用MSEL(3..0)=00104、nSTATUS,CONF_DONE,nCONFIG，nCE这4个PIN一定要接二、制作JIC文件通过JTAG直接烧写EPCS芯片时，实际是JTAG通过EP3C25芯片中的烧写制作程序来烧写EPCS芯片，所以不能再用SOF文件，它用的是JIC文件。下面我们用quartus将SOF文件转选成JIC文件2.1进入文件转换窗口，点File菜单中的“ConvertProgrammingFiles.....”打开窗口窗口如下2GaosMake2.……
