Subject: IBIS Bird 64 - Package Model Selector suggested changes

From: Scott McMorrow <[email-masked]>

All,

SiQual would like to suggest that we add min, typ and
max columns to the Bird 64 - Package Model Selector.
This will allow a simple mechanism for defining
multiple package corners that are logically associated
with a particular package type.

A simulator would select a package type using the
Package Type column.

A simulator would select a package corner using
the Typ, Min and Max columns.

These selections can be made independently within
the simulator in order to "sweep" the entire design
space.

See below.

regards,

scott
