hi,
Deepa .As far as EM problem is concerned it is the same in any tool.The Best possible solution can be to increase the number of VIAS (VIA array) if possible .The detailed info about this can be seen in any Rules document of Fab suppoting your design.Power routing also needs to be checked once again,like increasing the width of stripes . And Floor planning techniques like placing the module which consume more power near the power stripes.If possible place apower ring around such a module.Hope All these techniques help you fix the problem.

hi,
While doing the EM , the check should be done with Average value of current but not with the peak value. The reason, the more average current the more heating hence exacerbates EM violation.The average value is +ve or -ve depending on the direction of your current. If you have some DC current in the design then the total EM should be checked against DC+Average value. As you have taken the peak value normally you will see the EM violations as it doesn't give the actual value of current flowing. Conform the same from your Manager.
Thankyou,

hi,
