Can GPIO pins being place at the I/O bank 1B when the ADC block enabled for Max 10 device?

Description

Yes, the GPIO pins can be placed at I/O bank 1B if you are not receive the critical warning message (16248) for Max® 10 device. Quartus® Prime software uses physics-based rules to define the number of I/Os allowed in I/O bank 1B based on the I/O’s drive strength. These rules are based on noise calculation to analyze accurately the impact of I/O placement on the ADC performance. The critical warning message (16248) will generate when the noise generated by the GPIO pin exceed the noise threshold.

The physics-based rules are available for the following devices starting from these Quartus® Prime software versions:

• From Quartus® Prime Software v14.1— Max® 10 10M04, 10M08, 10M40, and 10M50 devices.

• From Quartus® Prime Software v15.0.1— Max® 10 10M02, 10M16, and 10M25 devices.

Prior to physics-based rules implementation, Quartus® Prime Software used the geometric rules which meant I/O bank 1B cannot be used as GPIO pins when the ADC block enabled.
