No License to Run VHDL Performance Optimized Simulation


What does the following message mean and how can I get rid of it?

Error : You do not have a license to run VHDL performance optimized simulation. Contact Aldec for ordering information.


If you have Active-HDL Plus Edition, it does not include VHDL optimization. This option is available exclusively in Expert Edition.

This does not mean you have a performance crippled license. It just does not have some of the additional optimizations.

To turn this message off, please do the following:

  1. Go to Design | Settings | Simulation | VHDL

  2. Unselect the Enable VITAL acceleration option.

  3. Click Apply and OK.
