How electromigration will impact on the Timing

 Electromigration: 

• For fixes of the Electro migration violations ,will increase the width of the metal layers 
• If will increase the metal width of that net ,the net resistance capacitance will decrease it leads to fastened the data
• Due to that that, the delay of the metal layer will decrease 
• Due to lesser values of the R and C the transition of that metal layer may increase it leads to hold time violations
• This timing violations are based on the life time of the chip
