strongzhy问:请问max3000a系列未用到的管脚是否可以开路
专家(Jing Kuo)答复:Yes. You can reserve the unused i/o pins as tri-stated input.
But you first have to include the empty pins in your design, and give pin assignments
to them. If you have a lot of such pins, say, 100. You can create an 100-to-1 mux,
compile the design, and back-annotate the pins. Then remove the mux logic and output,
but keep the input pins in the design. Also remember to remove the mux output from pin
assignments. This way the 100 pins would be reserved as tri-state inputs
tinazhu问:请问关于设计的功耗问题,不知道在仿真中的精确度是多少?

何操作?
专家(Bill Yuan)答复:flex系列芯片无法加密,不过用户可以在系统中在设计一个EPLD,将一部
分功能用epld来实现,并将此EPLD加密,可以实现整个系统的加密;可以在线更改配置以实现新的
功能,需要预先将所以功能设计好,并将配置文件存储在存储器中,在不断电的情况下,用控制逻
辑或微处理器重新配置新的数据就可以实现新的功能
quguangn问:quartus II 与 max+plus II 有何区别?为何要分成两个开发系统?
专家(ivan Li)答复:QII 和MP2最大的区别是对支持的器件的不同.当然在做设计时,QII和MP2的
功能基本上都能完成任务, 只是在界面上有一些不一样. 不过ALTERA主要会向QII 发展, 现在所有
的MP2 PROJECT 已经可以在QII中完全兼容.
kevin_li79问:您好!请问CPLD和FPGA的主要区别是什么?
专家(Edward)答复:CPLD和FPGA的主要区别是:EPLD是EEPROM的工艺,FPGA是SRAM的工艺,也就是说
EPLD内的程序掉电后不会丢失而FPGA掉电后会丢失每次上电需重新配置.但SRAM工艺使FPGA容量越来
越大.
