I/O Pin Count, LVDS Channels, and Package Offering
|1||Estimate the number of I/O pins that you require.|
|2||Consider the I/O pins you need to reserve for debugging.|
|3||Verify that the number of LVDS channels are enough.|
Determine the required number of I/O pins for your application, considering the design interface requirements with other system blocks.
Larger densities and package pin counts offer more full-duplex LVDS channels for different signaling; ensure that your device density-package combination includes enough LVDS channels. Other factors can also affect the number of I/O pins required for a design, including simultaneous switching noise (SSN) concerns, pin placement guidelines, pins used as dedicated inputs, I/O standard availability for each I/O bank, differences between I/O standards and speed for row and column I/O banks, and package migration options.
You can compile any existing designs in the Intel® Quartus® Prime software to determine how many I/O pins are used. Also consider reserving I/O pins for debugging.
