How to protect the FPGA IP?

Hi guys,.

I have developed an application of FPGA and build the VIs as a bitfile. I wonder how to protect it?

If others purchase my product with the same hardware and simply copy my bitfile, it will work too, no?

Is there than a unique material of FPGA associated ID I could get using LabVIEW? This way I could use a simple method of associated with protection ID and include it in bitfile.

Anyone know about this? Thank you very much!

Hi Bruce,.

In the FPGA code, you can programmatically read the cRIO module serial numbers and make sure they are the same whenever the system boots. Of course if a module goes bad, you will need to ship a new module and bitfile. There are various USB dongle manufacturers style you could probably get to work without too much difficulty: http://www.microcosm.co.uk/dinkey_pro.php. It really depends on if you try to make it difficult to pirate or impossible. Sell a complete package of material that you describe is probably already pretty safe, unless you plan to load a lot of the added value of your FPGA IP.

    Well, in my opinion, you must declare the laptop as a carry-on

  • How to pass the FPGA DI implemented FPGA vi pins to RT impemeted vi

    Hello

    I use two "FPGA sbrio' DI to implement the data RS232 (RX, TX)

    I'm now able to communicate with 1 deveice with this Protocol.

    I want to communicate with 3 device (in parallel) in the FPGA thought, copy the following (RS232) code.

    the pins are coded inside main code main FPGA RS232,

    "I have three RT vi to communicate with 3 different devices using this code), but now I want to communicate with them simultanouly. so, how can I configure the FPGA through pines

    so I need to each vi to specify DI pins to connect with via rs232, how do I do this?

    Kind regards

    Your architecture must change a lot to get it right.  You should read the data through a FIFO instead of use the interface on the front panel.

    I recommend that you change your VI so that it is a Subvi.  Make sure it is reentrant.  For starters, you can pin Numbers and a reference to FIFO.  Then in your main VI, you call just this VI three times with different constants at the entrances to designate different pins to use.  Use a DMA FIFO for read data that must be sent with some additional data to tell you which bus to send to.  Then, you pass just the data along the via FIFO belongs to the port you are writing.

  • How to protect the use of the phone

    We have a conference room with a 7937 conference phone.  Another company is going to start sharing this room so my task is to find a way to protect this phone are not used by the other company.  Ideally, it would be a kind of PIN code on the phone itself to wake up the phone or make it able to send and receive calls.   We would like to avoid the option where we just lock the phone in a closet until they are ready to use it.

    I don't know if there is a simple solution or not.  Deployment of 802. 1 x seems like overkill, but mabye it's my own inexperience with this feature.

    All recommendations are welcome.

    How about giving the phone a dummy extension with a partition and calling search space that don't carry anywhere, then using mobility extension to sign in the phone.

  • How to protect the land from the update

    Hi all

    I am using oracle 10 g forms,

    I created a form and the form has fields of 15 15 fields I need only 5 fields need to be updated by the user. All fields must be protected from the update.

    I put the update allowed the 'NO' in the property palette and I tried

    Set_item_property('BLK.) Field_Name ', Update_allowed, Property_false); for these trigger pre_block and also I tried when_new_block but it does not work, all can tell me how to do this.

    And one more question how do I move the cursor to the first record, when I get back a value and press the button of the field is questioned and new block opens with the data, but the cursor is in the last line that is a blank line, then it must be in the first line. I tried premier_enregistrement but it dosnt works.

    All can tell me how to do what you please.

    Thanks and greetings

    Hello

    Set_item_property('BLK.Field_name',Update_allowed,Property_false); for those item in pre_block trigger and also tried in when_new_block but it doesnt works, Can any tell me how to do this.
    

    trigger for pre-registration or time-new-record-instance
    write as

    if condition then
    Set_item_property('BLK.Field_name',insert_allowed,Property_false);
    Set_item_property('BLK.Field_name',Update_allowed,Property_false);
    else
    Set_item_property('BLK.Field_name',insert_allowed,Property_true);
    Set_item_property('BLK.Field_name',Update_allowed,Property_true); 
    
    And one more question How to bring the cursor to the first record, When i enter a value and press button the field is queried and new block opens with data, but the cursor is in the last line that is empty line, So it need to be in the first line.I have tried FIRST_RECORD but it dosnt works.

  • How to protect the health of your battery on the t420

    Hey,.

    What is the best way to protect the health of your battery? When my laptop recharges and 100%, will again be the discharg and charg battery upward or the laptop gets its power directly from the power supply?

    THX in advance

    My recommendation is to install ThinkVantage Power Manager. Then the battery tab, and then click maintenance of batteries. This allows you to set the Mode of Charge to something like min 40%/max 80% in order to avoid charging the battery to 100%. Keep the battery at 100%, while the ThinkPad is on AC for long periods will hasten its deterioration.

  • How to protect the inductive tension peaks DAQ modules

    I just ordered the USB DAQ 9221 module. He reads voltages up to 60 volts. My loads are inductive. I have been using diodes to avoid the negative peaks. I used a scope on one of the inductive loads with a diode. I have a recorder-560 volts. Led TV type is better? If yes how can I specify a part? I don't want to blow the DAQ module.

    Thank you

    Philippe

    Philip,

    It depends on.  What is the source of your signal? What is the range of voltage and frequency of the desired signal? How it is coupled to the inductive loads? How fast are transients? The amount of energy they contain?  What kind of grounding circuits you have?

    The diodes are often good protectors.  TVS diodes are usually specified and evaluated for transients, then the conventional diodes are usually assessed BOF functions of rectification.  Some systems may require several protection devices chosen to complement each other.  I have seen systems with discharge gas, MOV, diodes and crowbars tubes.
