Seats in IP core floating license

Hello Intel team,

Greetings of the Day!

I am Bhaumik Darji. I am working at System Level Solutions Pvt. Ltd (www.slscorp.com).

We are having various IP cores including USB IP cores.

We are providing node locked as well as floating server license which can be used with Altera Quartus tool. Customer can select number of seats based on requirement.

While using floating license for single seat, we are facing following problem. We are getting following type of warning when we try to compile design on single machine with two Quartus tools running simultaneously.

Means, at any point of time, it is allowing us to compile only one design at a time.

We were doing some research and came across following: How Many Floating Licenses Do I Need?

It states single seat floating license should facilitate one user at a time to have multiple compilation.

On other hand, if we use node locked license, it is allowing us to compile multiple designs simultaneously.

May you please suggest what could be wrong with floating license which we are generating for our IP core? As per my knowledge, utility was shared by Altera team many years back.

We will appreciate any feedback on this. Also, let us know if more information is required.

Kind Regards,

Bhaumik

    This could be a confusion of Quartus licenses vs. IP-specific licenses. Quartus follows the rules on the page you linked to. But whatever IP in your design that requires additional licensing may not.

      Hello,

      Thank you very much for your prompt response.

      At present, we are using utility CPT v6.52 for generating floating server license for our IP cores.

      May be Altera support team would be able to check whether there is any update in this utility which could help us to generate license having behaviour similar to Altera Quartus license. (i.e. single seat floating license which does not prevent single user to compile multiple designs simultaneously.)

      If any other information is required, please let us know.

      Kind Regards,

      Bhaumik

    As I said, the issue could be due to IP in your design. Is there any licensed IP in your design that perhaps has its own licensing rules?

      Hello,

      Thank you very much for your response. Yes, we have one encrypted IP in our design. And in fact, that is our own. I suspect that this issue might have to do something with license generation utility which is being used. May be ours could be older one.

      Have you ever created such license for your IP if any? If so, may you please share version number of that utility?

      If not, no problem. Let's see if Altera support team has any feedback with respect to this or not.

      Kind Regards,

      Bhaumik

      Hello Aiman,

      Thank you very much for your assistance.

      So, according to following: Can I perform multiple compilations using the Quartus II software at... , it seems expected behaviour and this should happen with floating server as well as fixed (node locked) license.

      But interesting thing for us is we do not face this issue while using fixed (node locked) license. We are seeing this when we use floating server license. It may be possible that there might be some configuration issue at our side in generating fixed node locked license. I will check with our internal team.

      Thank you again for your help.

      Kind Regards,

      Bhaumik
