A valide license was not found for simulation.

Jump to solution

I'm running Vivado 2015.4 Design Edition in Ubuntu 18.04. I followed this link and changed the name of the nic so the license manager is able to read it correctly. But running simulation fails with error:

-----------------------------------------------------

Vivado Simulator 2015.4
ERROR: [Simtcl 6-50] Simulation engine failed to start: A valid license was not found for simulation. Please run the Vivado License Manager for assistance in determining which features and devices are licensed for your system.

-----------------------------------------------------

From license manager I see:

-----------------------------------------------------

License name: Simulation 

Expiration date: Permanent

Version limit: 2015.08

License type: Nodelocked

# of seats: Uncounted

# of sets used: 0

Host ID in license file: xxxx (nic address)

Host IDs match: Yes

License CRC: Okay

License vendor string: xxx, Vivado_Design_Edition,software,permanent,xxxxx

-----------------------------------------------------

So my license should cover this version of vivado, and it reads the correct host id. Why does it complains license is invalid for simulation?

Hi @fiedel,

 

From the env.txt file i see that you are using Vivado 2015.4 and you have the Vivado_Design_Edition license which has a version limit of 2015.08. The license will enable any version of the design tools released during or before the month specified by the Version Limit. Hence, with this version limit you will be able to use Vivado 2015.2.1 and earlier Versions of Vivado tools.

Hi @fiedel,

 

Share your license file. and Run "report_environment -file <filepath>/env.txt" in tcl console and share env.txt to evaluate.

Hi @bandi

This explains the problem. Thank you.

 

Btw, how is this version limit calculated for licensing? Is it a certain period from the date of purchasing? We are considering buying several licenses, and we'd like to know this beforehand.

Hi @fiedel,

 

>> how is this version limit calculated for licensing? 

 

The Version Limit corresponds to a year and a month (for example, 2010.04 corresponds to April 2010).

As mentioned in my above reply the license will enable any version of the design tools released during or before the month specified by the Version Limit.

 

Hope this clarifies.

Thanks & Regards,
Sravanthi B
