Thanks for your question. If you purchased a "perpetual" license for the product, you can use the version you purchased as long as you want.
This information can be found on SupportNet without having to log in. Here is the link: https://supportnet.mentor.com/about/policies/authorization_code_duration_policy.cfm
And here is the published policy:
Perpetual Licenses at Declined Sites: A declined site is a site without any products on current support contract. Perpetual licenses at declined sites will have Authorization Codes generated at the last supported version with dates that extend for five years.
Thanks for you your help, its getting me closer to finding my answer... How do I determine if the license is a "perpetual license"? ...I checked the license, no where do I find this info or any other info that states otherwise. Where would this info reside?
Generally, if your license expiration date is three months after the end of your support contract, your license is perpetual. But there's nothing explicitly indicating a perpetual license in the license file itself. For that you should refer to the details of your order.
Thanks for this info.
