Max 10 Pin Compatibility

[F_P_G_A]

Hello Community,

I can use in my design either 10M04DCF256A7G or 10M08DCF256A7G. They are pin compatible. But what if I want to use the other members of the family like 10M16DCF256A7G, 10M25DCF256A7G or 10M50DCF256A7G in the same design. Are they still pin compatible? According to the datasheet there are 3 pins that are different. In case of 10M04DCF256A7G and 10M08DCF256A7G they are unconnected hence my design has no connections at these pins. The other family members has connections/functionalities at these pins. But what happens if they are unconnected?

P.S.: 

- 10M04DCF256A7G and10M08DCF256A7G are just unavailable. I need to find other solutions.

- I need 4000-6000 devices per month. 

Thanks a lot for the answers!

Hi FPGA,

As long as they fall under the same package it shouldn't be a problem.

You can refer to the Migration Capability Across Intel MAX 10 Devices on page 8 in the following document:

Intel® MAX® 10 FPGA Device Overview

Hello,
to be sure not to overlook any necessary connection in migration compatible devices, I'd proceed as follows

- select all intended migration devices in your Quartus design
- place a top level entity with all port signals and signal direction

- optionally add basic functionality for dedicated signals (PLLs connecting to clock in- and outputs, SERDES IP)
- assign locations and IO-standards for all signals
- compile the design

- review the required connection in generate .pin file. You particulary find all pins needing connection to GND or supply voltage for migration devices

Hi FvM,

As long as there's no error nor significant warning during the compilation process, plus with all your mentioned procedures above, it should be no issue.
