Regarding IR Drop Analysis

[arjun1110]

Hi,

For a given BEST (S_-40_1.1) and WORST (W_125_0.9) PTV corner,
Which is the worst corner to perform IR drop analysis? or In which PTV corner we will see high IR drop?

Please share your answer.

Regards.

Hi,

Any answer?

hi arjun,
the worst condition or highest IR drop will be in BEST condition because the cells will be switching faster (rise-fall times lesser) and hence during clock rise-fall times, more flops & last stage clock buffers will contribute to peak current and you will see more IR drop

Hi Amartyad,

Thanks for sharing your answer.

How capacitance does depend on the temperature? How does resistance depend?
