How do I use the Altera PDN Tool to evaluate decoupling requirements for a MAX 10 device? - 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.
