Understand the power supply specifications based on the type of FPGA and prepare pin connection guidelines

start design

Now let's start power supply selection using EPE.

Select FPGA usage conditions Part 1

Now let's start power supply selection using EPE.

• Select Device on the Main tab. (See image 01 <1>)
• Select Power Charactrization as Maximum. (See image 01 <2>)
• Select Power Rail Configuration in some cases.
• This time I chose SX FPGA and HPS Shared. (See image 01 <3>)

Select FPGA usage conditions Part 2

• Enter the required information on each tab. (This time, enter only the Logic tab)
• It is assumed that Look Up Table, FF, and Clock Frequency are used with the selected device fully utilized. (see image 02)
• When you return to the Main tab, the current consumption increases due to the above settings, and a warning is displayed in red. (see image 03)

Clear warning

• If you select the Report tab, you'll see that two different voltages that should be distinguished are now one power rail. (see image 04)
• Since it can be confirmed that 1.5V is mixed up with the 2.5Vin rail, increase the rail by changing the value of the Regulator Group of the 1.5Vin rail from 2 to 3. (see image 05)
• The error has been resolved and the number of regulator groups has increased. (See image 06)

The above is a concrete example of confirming the necessary power rail using EPE. However, depending on your design, it may require additional current consumption or additional power rails. Please use EPE while checking each time.
