2 years agoHi there,
It seems like SmartVid error. In a word, the device cannot communicate with voltage regulator by PMBUS/ There is some advice:
- Check the line of pmbus_clk pmbus_data between device(SDM) to voltage regulator
- check the PMBUS setting in quartus: Assignment->Device->device and pin opinion->Power management&VID. These setting should be based on the datasheet of voltage regulator.
More information can refer this link:
Best regards,

2 years agoHi,
We have set the SmartVID settings as recommended, but unable to calculate 'Linear format N' value for LTM4680 power module for output voltage of 0.85V. We have tried both the cases by setting Voltage output format to 'Auto discovery' and 'Linear format' with N value as -12, -14, -15, but programming was unsuccessful
Please tell us how to get the N value
