My chip has dual power supply, meaning AVDD and AGND for analog core and DVDD and DGND for digital core. In the .s2i file Pin List, I specify each to be POWER and GND model accordingly. But when I run the s2ibis3, it will only connect a voltage source to AVDD and not to both the VDD. How do I specify the pin list for this case? Thank you.
