I started to say the bump C should be part of the package but in reflection
it seems to be part of the die. I'd vote for as part of C_comp because it
is part of the metalization on the die.

Subject: [IBIS-Users] IBIS bump question

Hi all,

For a wire-bond package, the RLC of the bondwire is generally considered
to be part of the package. For a flip-chip package, is there a convention
for how the bump parasitics should be handled? Is the bump to be
considered part of the package, or part of the die(C_comp)?

Regards,
