a Variant source block is used in 'mcb_pmsm_operating_mode_f28379d.slx' model example to switch betwen SIMulation mode and CODE-generation mode. Inside Varian source block, there are two variables: mcb_isCodeGenVar() and mcb_isSimVar().
Could you please tell me where and how are those variables set? When the model decides what mode is to be chosen? Do I have to play with a Variant manager?
