    rp-prew got a reaction from Commanderfranz in analog discovery voltage concern   
    Dear ab,
    Could it be possible to see the circuit that you wired up? it would give us a better view and may help us understand what could be wrong. I did go through and make a quick circuit and I was also getting about 4.8 V. I will read through some of the reference manual to see if there is a reason for this. if you could post a picture of your set up that would be fantastic.
    Thanks,
    Bobby

    rp-prew got a reaction from Commanderfranz in NI Circuit Design Suite Installations   
    Dear mb7270,
    I had to do some research about this software. This is a NI academic product so I do not have all the information I would like to have to answer this question. What I have found may be able to answer. Looking at the full version of Multisim software on NIs website I have found that when you purchase that program you will get a product license which you would input into an account on NI. From there you would be able to down the program and then use your account license to be able to use that program. It appears you would be able to upgrade to a new computer and use that license on the new computer. That information is for the the Full-edition of Multisim. While I do not know if that applies to the student edition I do have a recommendation. If you go onto the NI website and go to their forums or contact their sales department they will be able to give you a more complete answer. I hope this helps.
    Best Regards,
    Bobby

    rp-prew got a reaction from Anding in Pin change to Ethernet PHY between Nexys4 and Nexys4DDR?   
    Dear Anding,
    That is a very strange case for pin changing so I went and checked the schematics. I found the two that in the two schematics for the Nexys4 and the Nexys4 DDR that the pins D10 and C11 have been flipped when connecting to the RXD1/Mode1 and RXD0/MODE0. The reason behind this is unclear to me but i'm glad you asked so that way in the future we can know that this isn't a typo. Thanks so much for pointing it out. I would have just assumed it was a typo.
    Best Regards,
    Bobby

    So the workflow for programming an FPGA is a bit different than what you are used to with programming a microcontroller. Once you have written out your hardware description language code (either VHDL or verilog), ISE goes through several steps to verify the design (Synthesis and Implementation), then generates a bitstream (a .bit file type) which is the file that will be used to program your board. iMPACT is the hardware manager that ISE uses to send these .bit files to your board via USB.
    There is a quick step by step guide on how to use iMPACT to program an FPGA on the Digilent Learn site, here. If you are just getting started, there are a handful of reference projects with code to demonstrate some of the boards functionality. They can be found at the bottom of the product page under the category RD. Let me know if you have more questions and I'll do my best to address them.

    rp-prew got a reaction from JColvin in Apparent problem -- solved.   
    No problem is a stupid problem. I have definitely done the same thing when writing my own code. We really appreciate you posting an answer to your problem though. It helps us out and other users. Thanks a ton. Good luck with your project.

    Also If you look at the product page for the Basys3 there are a couple demonstration projects at the bottom of the page. Check those out if you want some different sample code.

    Hi Muthupriya,
    I think I may have the answers you are looking for.
    1) Do you mean a .xdc file? the .xdc files are the constraints for the board; so the file will define the labels for the ball locations of the basys3 board. It pretty much is defining the board locations to the software. This file is case sensitive so watch out for your typing. The .v files are the actual project files for Vivado. .v files are the Verilog programming language files.
    2) You can use either VHDL or verilog to program the Basys3. They can be interchangeable but it is best to keep to one language at a time. You can choose which ever one you're more comfortable with but it's always good to try your hand at something new. 
    3) The Basys3 is exclusively made to be used in Vivado design suite. Vivado is made by Xilinx though so that's another answer to your question.
    I hope these answered some of your questions. If you have any other questions feel free ask. We do have a FPGA forum section if you would like to browse through there. Also check out the wikipage for more on the Basys3. https://reference.digilentinc.com/doku.php?id=basys3:basys3#documentation
    Good luck,
