What Is The Importance Of Ir Drop Analysis? |
|
Answer» IR drop determines the level of voltage at the pins of standard cells. Value of acceptable IR drop will be decided at the start of the project and it is one of the factors used to determine the derate value. If the value of IR drop is more than the acceptable value, it calls to CHANGE the derate value. Without this change, TIMING calculation becomes optimistic. For example setup slack CALCULATED by the tool is less than the REALITY. IR drop determines the level of voltage at the pins of standard cells.
