Licenses have both an expiry date and a version number.  The expiry date is easy to read, but what about the version number?


The version number (sometimes referred to by Mentor as the “Exact Access Date”) determines which version of the product you are allowed to use.  If you have a support contract in place when a version of software is released will you be able to use it.


The version number appears as the 4th entry on an INCREMENT line in your license file:


INCREMENT msimviewer mgcld <version> <expiry_date>


For example the license below has version 2014.050:


INCREMENT msimviewer mgcld 2014.050 31-may-2015 ...


Recent releases and the relevant expiry dates are listed below.


The table also includes the version of FlexNet (license server software) which is required for the release.

If you cannot run the latest Questa / Modelsim because of the version number in your license file, please contact Mentor Graphics support.

With the PADS VX release just around the corner, now is the time to download your most current license file from SupportNet, to check and make sure it will support the new release:

Which PADS Flow release am I entitled to use?


If your support contract has lapsed and you would like to run the PADS VX release once available, please contact your local Mentor or Distributor sales office to find out how to get back on support.



I stumbled on an interesting little browser trick this week. You can make your browser take notes.


Paste the following into the address bar and press Enter:




You can then use your browser to type in text as notes or just something you want to paste elsewhere. You'll have to Ctrl-A and paste them somewhere to save them but this is a good way to type out some text that you can then use however you want.



When you use the set or echo commands in a DOS command Window to learn the value of an environment variable, it's no problem when the value is only one or two components. But when it's a PATH variable or some other one that has many components, it's not as much fun because the output is a single, wrapped line which is more difficult to read. For example:



That's no fun at all. Try this: echo %PATH:;=&echo.%



Now that's more like it.


Of course, I never remember the syntax, so I put mine in a batch script and add it to my search path.


It works for license file variables too, just replace PATH with MGLS_LICENSE_FILE.


That's it for this week! Tune in next week for another useful tip.




Special thanks to my colleague Clinton Wittstruck who provided this information.
