  1. Thank you so much for the information, Dan.
  2. Hello, I am using the cmod s6 eval board as the reference for my prototype board. I wonder how many board layers do I need if I am going to use the same package like the cmod s6 package XC6SLX 4-2CPG196 does? In additon, when I use the iMPACT to reprogram the chip flash, it took me 12 min for burn the code in the flash, is there any suggestion I could speed up this process? Thanks,
  3. Thank you Ivoudour, The Warning goes away. you are correct, it is a Fclk / 2^(divider+1) divider, the compiling succeed without the warning. There is another issue when I try to burn the program into the NEXYS 4 board, it is my first time to use this eval board. It still not working as I slide the sw changing the input. I basically just use the "Configure Target Device" and program the device with .bit file generated from the design(when i program the chip, it went through without error message, so I assume it is not a chip or board damage). I have also tried the Adept software a
  4. Hi Everyone, I am developing a design based on ISE 14.7, Artix-7 CSG324 NEXYS4 eval board. For testing purpose, I wrote a simple clock divider code as following, but the compiler keeps warning me: Line 31(red line): Result of 32-bit expression is truncated to fit in 1-bit target. The RTL schematic looks the same as I expected, If ignore the warning and program the eval board, clock frequency wouldn't change when SW0 - SW3 input changed. I wonder if it is because of compatible issue for the compiler(most people use vivado for artix-7)? But on the Xilinx website it says the ISE wi
  5. Hi Jon, These information are really helpful, Thank you so much!
  6. Hi everyone, I am new to the Xilinx CPLD XC2C54A, I bought a Cmod: Breadboardable CoolRunner-II CPLD Module recently and try to use the platform do some experiment for our design. However, besides DataSheet and Schematic I didn't see any tutorial or example projects available for this board on digilent's website. If possible, could someone point me to the resource that could help me learn about this Architecture? Any sample code, tutorial I could follow? Thanks ahead.
