How do I use the Altera PDN Tool to evaluate decoupling requirements for a MAX 10 device?
Description
To evaluate decoupling requirements for a MAX® 10 device you can use the device agnostic version of the Altera® Power Delivery Network (PDN) Tool.
To calculate the target impedance of each MAX 10 device supply, you should use the following transient current and voltage ripple percentages:
| MAX 10 Supply Rail | Transient Current | Voltage Ripple |
| VCC | 50% | 5% |
| VCCIO | 100% | 5% |
| VCCA | 10% | 5% |
| VCCD_PLL | 10% | 3% |
| VCCA_ADC | 50% | 2% |
| VCCINT | 50% | 3% |
Setting Ftarget to 70MHz or higher should result in a robust PDN.
