phdb问:altera公司的这两种器件的安全性如何?其解决方案又如何?如何保护器件的ip!
专家(Edgar Wong)答复:When programming MAX, user can turn on a secuirty option which
prevents programming image from reading out of the device. Regarding FPGA in general,
such as Cyclone, because of its high density and routing complexity, it is extremely
difficult as they do not know exactly the internal architecture of the device. Even if
people can reverse the bit stream to derive the LUT structure of the design, , to try
to reverse it back to the original gate level logic, not to talk about the RTL or
architectural level, it would be near to impossible. If they are concerned with people
just copying the FPGA content and reproduce the same board, they can put a small
portion of the design into a CPLD.

可以使用第三方的仿真软件来仿真如modelsim,vcs等
21IC问:Mazz提问:有人说MAXPLUSII编译时如果提示可用资源少于20%,可能会导致逻辑仿真波形
对,而实际运行可能会不稳定,是不是这样?

如果不是这样的话,在很多逻辑时钟等地方那个会有问题?
专家(eric deng)答复:MAX+PLUS II software will choose the best placement for design.
Base on this placment, you can get most effecient performace. If you are using manaul
pin-locking, it may not be the best placement, so it may cause the routing problem. So
we suggest you let software to do auto pin assignment to get best performace.

专家(eric deng)答复:PLD & PLA is the general term for all programmble deivce. PLD
is including FPGA & CPLD. For FPGA, is Gate Arry like architecture. It is SRAM base,
so you need to have a ROM to contain your data. Also its timing depends on the
rounting . However, it has rich register, so it is more suitale for more complex
design like counter. For CPLD (EPLE), it is PAL like architecture with fix timing.
And it is EEPROM base device with rich logic. It is more suitable for glue logic
design like decoder.

information ( email, address, phone ) My email: horace@cytecht.com
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?
专家(Edgar Wong)答复:Dynamic power consumption of a device highly depends on the
toggling frequency and data pattern of its inputs. Therefore, if the simluation
stimulus are closer to the actual operation condition of the device, the accuracy of
power consumption estimation will increase.

the assembly language description for customers.
zhouzhengf问:maxplusii对vhdl语言的支持有限,quartus在这方面有否加强?
专家(Edward)答复:QuartusII support better with VHDL,but we suggest the customer use
the 3rd EDA tools to synthesis the VHDL or Verilog,then use our QuartusII to compile.
xch2000_1980问:下载时总是提示unrecognised device or socket is empty,请问是什么原因(用
ByteblasterMV,WINXP系统,EPM7512AEQC208-10)
专家(Edgar Wong)答复:MAX+PLUS II Help describes several causes for this error
message. The following are three additional possibilities that are not listed in
MAX+PLUS II Help: You may receive this error if you attempt to program a device when
the Altera download cable is not powered. These cables receive power from the printed
circuit board (PCB). Ensure that the PCB is powered properly and that the Altera
download cable is securely connected to the PCB. This error may also appear if you are
attempting to program or configure one device when you actually have more than one
device in a Joint Test Action Group (JTAG) chain. Click on Select Programming File
(JTAG menu -> Multi-Device JTAG Setup). Choose your file and click OK. Click on Detect
JTAG Chain Info.
