RE: [IBIS-Users] IBIS dual power supply

Hi Syed,

 

I thought of that too as the last resolution. Is it an acceptable way?

Thanks.

This may not be the best solution but you could edit the .sp file and
hardcode the VDD connection.

Hi experts,

 

Need your guidance in a simple question. 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.

 

Best regards,

Mei Yee
