Altmult_add in MAX10

Hello,

I am trying to use an embedded multiplier in MAX10M50 device. I am using Quatus II 15.1

When I double click on ALTMULT_ADD in the "IP Catalog" pane, I get "Save IP Variation" dialog and then Quartus saves cnx file (I select my project directory as a destination for the file). Once I press Enter the dialog closes but the Wizard doesn't open.

For LPM_MULT the wizard works and I get files lpm.v and lpm.qip.

Am I doing something wrong?

Thank you,

Vitaly
