Hold time fix after tapeout

[parkpika]

What can you do to fix hold time after tapeout? Can you fix by decreasing voltage or operating at higher temperature so the data is slower?

 

[rca]

Certainly, but you already know you could have an hold time violation in your chip?

 

[parkpika]

No I was just wondering because I've been asked this question in an interview before.

Reducing the voltage should help with the hold timing violations.
I dont know how r u inc the temperature to fix it ?

 

[mail4idle2]

Reduce the voltage and decrease the Operating frequency

 

[pavanks]

Reduce the voltage and decrease the Operating frequency

How will the frequency effect the Hold time ?

 

[rca]

The frequency does not impact the hold time.
