How to do multi-voltage domain simulation

wangyunxin


As shown in the first picture, if I have two digital modules, but their supply voltages are different, the red part is at 1.8V and the blue part is at 1.2V.

So I set the voltage domain in the second picture, but the simulation time but reported an error, how should I solve it? How to do the correct multi-voltage domain simulation?

    You need to change the discipline set for these. To do that please click on the 'Advanced Setup' button and then the 'Extended' tab.

    This will then show you the option to change the discipline for the selected row in the above table.

    This should then allow you to proceed.
