In removal timing report, required time additional buffers are inserted and some miss conceptions

[@zihanduoduo]

clear explanation, thank you

[@truptichauhan3634]

clear concept with reports👍

[@VivekGupta-je2oe]

Good👍 job

At 5:23,can i know why did you add clock uncertainty in clock path for removal check

[@compat1836]

Hi, Can you please explain why library recovery time is positive and got added in required time at 10:00? Generally we will subtract it from clock period right?

[@CantResist717]

I think it should be negative as well

[@praveengupta1705]

thank you so much

[@thanhdesert]

time 9:48, library recovery time should be -0.09 not +0.09 ? so data require time should be: 11.8 ???

@@VLSIAcademyhub was wondering the same while watching the video. Could this please be corrected

@@shreyatasharma1505 Actually Library recovery times are sometimes negative as well. So when you subtract a negative recovery time, it gets added. It is similar to negative hold timing. In timing report we will sometimes see hold time getting subtracted from Data Required time, for min delay report, the reason being negative library hold time.
