The Die Import module needs to know which pads are to be connected to an I/O finger, which pads go to the ground ring, which die pads go to the power ring and which die pads are no connect and so can be ignored.

This information is tabulated so that the finger generator knows how many fingers to place and where to attach wire bonds.

The die netlist has a netname assigned to each pad. By inspecting the netname for each pad and comparing it to entries in the keyword file, the Die Import module can make the correct assignment.

Default Name/Location

You can use the dialog box to select any path/filename but the default path and file name are:

c:\die_in.ini

POWER VCCI
POWER VCCO 
GROUND VSSO
GROUND VSSI
NOCONNECT NC
NOCONNECT NOCONNECT
GROUND VSS[0]

Column 2 - net name for that type of signal. Currently the comparison is for whole words (no partial match or wildcards) and is case insensitive but in future revs we may make the comparison case sensitive.
