[Common 17-345] A valid license was not found for feature 'Synthesis' and/or device 'xc7a35t'.

I just downloaded the Vivado 2015.2 ISE Webpack which has a free licence. However, eventhough I tried three times to show the licence to the program, the program gives the error.

What is wrong with my program?

Hi @alper.kagan.kayali,

 

Would you be able to provide the 'report_envrionement -file xinfo.txt' log from the console?

Thank you,

Devin

webpack doesn't support all the devices . Check the list of supported device s here

Hi @alper.kagan.kayali,

 

As mentioned by @balkris not all the devices are supported into webpack edition. However from UG973 v2015.2 (p10), it should be supported in 2015.2 webpack. But you need a valid webpack license.

 

Try to open vivado license manager and see if you have a valid webpack license else you can generate a new license for free in your account.

 

You might want to use 2016.1, there is no longer a license required.

 

Kind Regards,

Hello @alper.kagan.kayali,

 

ISE WebPACK won't work for Vivado, only for ISE. You'd need a Vivado WebPACK license instead. 

 

Hope this helps.

 

Kind Regards,

Anatoli

Re: [Common 17-345] A valid license was not found for feature 'Synthesis' and/or device 'xc7a35t'.

I have been using the same software with the exactly same computer one month ago and it was working fine. Then somehow my HDD broke and I had to replace it with an SSD. Then after I installed vivado it started to give the licence error. I downloaded the old licence I was using since the licence does not matter for Webpack versions, but it didn't work. Tried to get a new licence and downloaded it, still didn't work.

I looked at it and it says that it is a valid licence. However it still doesn't work.

Hello @alper.kagan.kayali,

 

Please note that in order to successfully use this device in Vivado (i.e. to be able to synthesis, Implement etc. your design), you'd need a Vivado WebPACK license for this. In your case, you have stated you have obtained an ISE WebPACK license. This won't work for Vivado.

Please log in to www.xilinx.com/getlicenses and obtain Vivado WebPACK license. This should work for you.

Alternatively, please usethe latest Vivado release and you won't even need a WebPACK license to target this device and you should then not see this licensing error.

 

Kind Regards,

Anatoli

Hi @alper.kagan.kayali,

 

The reason why it was working previously and it is not working anymore is because the license is tied to a specific HDD. If you changed your HDD, you need to regenerate a new webpack license.

 

When generating the new license, you need to create it for the HDD number you can find on Vivado License manager:

But again the simplest way is to use a newer version of vivado.
