Subject: User Unhappy About Mentor Changing The Eldo Licensing Mechanism
Hi John,
Please keep me anon.
We've been using Mentor's electrical simulator "Eldo" fo a long time now.
Until recently (version 5.7), a user could run several Eldo simulation jobs
simultanuously on a given machine using a single key - one key par
(user+machine). I call this a user-based licensing mechanism.
In the newer versions of the Eldo simulator (version 5.8), each simulation
job checks-out a key, even if it is the same user on the same hostid.
I call this a job-based licensing mechanism.
This change is very important as this leads to buying as many licenses as
you run jobs in parallel compared to the previous mode where you needed one
license per user of the tool. The first licensing mode allowed users to
take advantage of multiprocessor workstations.
The price of the simulator did not change.
I have several questions now:
- Is this a license terms violation?
- How do other simulators (HSPICE, Spectre, etc.) behave? User-based
or job-based?
- Is Eldo really faster than hspice?
Thank you for your help.
