Description

General Description: 

The Virtex-II SPICE netlist contains the following voltage nodes: VCCI, VCCO, VGG, VSS, and VDD. How do these nodes correlate to voltage supplies on the device?

Solution

These nodes and device voltage supplies correlate as follows: 

VCCI -> VCCAUX 

VCCO -> VCCO 

VGG -> Internal memory (do not modify) 

VSS -> Ground 

VDD -> VCCINT 

VBG -> reference for internal LVDS bias circuitry (do not modify)
