spartan 3e usage guide

[mrarslanahmed]

hi all

i need ur help regarding fpga programming , i have spartan 3e and installed xilinx already i now verilog but cant transfer my knowledge in the spartan 3e kit if any body help me

thanks

To work with the Spartan 3e you need Xilinx ISE software.
Start a project, synthesize your design and program your device.

You have to be more specific with your questions if you need further help...

yes u are right actually i am very much scattered, i am having xilinx 9.1 and have sparten 3e i have downloaded some tutorial but cant find any direction, to begin with i just need to switch on an led so that i can get some confidence on my coding and on the kit as well

 

[shaiko]

What's the problem?
Where are you having difficulties??
Building a project with Xilinx is pretty straight forward...

i have downloaded a tutorial it helped me a lot , i have programed the spartan 3e but when i switch it off and turn it on its memory vanishes, so i have to reprogram it again, this is very confusing for me, plz help me

Well, the bit files are generally downloaded into their internal volatile memory, which gets cleared when the power is turned off. To program the FPGA permanently, there are options to write the program in its FLASH or similar non volatile memory attached to the FPGA. For most cases, the reprogramming of FPGAs after booting would suffice. But if you wish to make your program sit in the FPGA even after the power goes down, please take a look at FLASH or similar non volatile memory programming features provided with the FPGA.

Hope that helps.

Thanks.

i have tried all the option for programming but it still not working well these include

Master Serial
SPI
BPI up
BPI down
JTAG

by changing pin setting at jumper 30 but still cant get the best solution, dont know which step i am missing

The FPGA binary is stored on Flash.

Are you aware you must save your binary to the Flash, and not to the FPGA, right?

Otherwise, we need more details to help you. Describe what you are trying to do and what error message you get. A screenshot might help as well.

 

[mrarslanahmed]

there is no error in the system , because at the end of the work it shows program succeeded but problem is it is volatile, i want it non volatile ,

also i need to know verilog if u can refer me some tutorial it would be very helpful for me

 

[pbernardi]

Again, are you programming the FLASH or the FPGA? What is exatcly the kit you are using?

Regarding the tutorial, here is a good one: https://www.asic-world.com/verilog/verilog_one_day.html

Apart from the ASIC world (which is undoubtedly a great resource for learning Verilog), there is also a book named "FPGA Prototyping by Verilog Examples" by "Pong P. Chu.". I found that book to be one of the best verilog references for FPGA programming. The book focuses on Spartan-3 FPGA as well, as far as I remember.

Also, please make your question a bit more clear so that better help could be provided.

Thanks.
