I/O Pin Count, LVDS Channels, and Package Offering

Table 8.  I/O Pin Count, LVDS Channels, and Package Offering Checklist
Number Done? Checklist Item
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.
