Hi zwangI believe that you are refering to "Virtuoso_APS_MMSIM_Lk" license. Actually this license is just for tracking the version of MMSIM license and is issued together with the actual "Virtuoso_Multi_mode_Simulation" license. You can refer to COS solution 11514566 for more explanation on MMSIM licensing.Best regardsQuek
