Crosstalk effect on electromigtaion vilation

[riti]

Hello,

if there is more crosstalk then it prone to more Electomigration violation? Is it true, if yes, Then what would be the concept behind it?

Crosstalk means capacitively and/or inductive
(AC only) coupling and the energy transferred
will be very low, sparse and reversing. Figure the
RMS current through the coupling network and
see what that current density looks like. Should
be negligible.

In terms of "violations" I doubt the EM rules check
has any idea about crosstalk, per se. Only what
a simulation shows for nets' DC / RMS currents
and what the engine says for net W (and the
embedded layer thicknesses, notching / thinning
and so on, which are fixed technology worst case
attributes).

I can't think of a scenario where the induced current via couling is higher than the current limit a wire can carry. It's not even close. For digital IC design, EM and crosstalk are considered separately.
