Why may I see continuous PMBus PWRMGT_ALERT assertations on my SmartVID implementation?

Description

Continuous PMBus ALERT errors you may observe are possible root causes of signal integrity problems on PMBus. The PMBus is vulnerable to noise coupling.

Resolution

To improve the signal integrity of PMBUS signals, consider try increasing the pull-up strength by reducing the resistance of pull-the up resistor on PMBUS signals.
