    Hi,


    You can use ModelSim - Intel FPGA Edition alone to perform simultaneous simulation with different users as you intended.


    If you install on two different machines I don't think you'd be able to perform simultaneous simulation with different users. It doesn't hurt to try though.


    Do you have any further questions?


    Regards,

Hi,


Can you give me the following information:

  1. Do you have other ModelSim instances installed in the server?
  2. ModelSim Starter Edition has a line limit of 10k lines, are your designs possibly exceeding that amount?
  3. Are you able to launch ModelSim successfully at all times?
  4. Does this happen no matter who the first user is?


Best regards,

Nurina

Hi Nurina

  1. We have also "ModelSim ALTERA STARTER EDITION vsim 10.5b " installed, but it is not used.
  2. The design simulates fine when no other users use vsim so it doesn't seem to be a line number issue.
  3. The first users have no problems launching and running simulation.
  4. Yes, it is not connected to a specific user.

If the first user only starts the ModelSim GUI and are not running a simulation, then the second user can use ModelsIm without any issues. If the first user has an active simulation, then the second user is kicked out after 5 min with "** Fatal: vsimk is exiting with code 4."
