RTAX Prototyping¶
To prototype the Actel's RTAX4000D on our design we use tree solutions, one home made and two made by Ironwood Electronics .
We used the first home made solution for our engineering model because this solution is cheap and allow us to use only one A3PE3000 fpga and is compatible with RTAX4000D pinout. The second solution is an improved version of the first one. This second solution is easier to remove if we want to solder a RTAX4000D-proto on the same board. The third solution allow us to test a RTAX4000D in tie-bar without soldering for tests such as Post Programming Burn In (PPBI).
First solution (home made)¶
You can easily get source files of this socket here: RTAX To A3PE Converter
The main drawback of this solution is that this socket isn't easy to solder.
Second solution (Ironwood)¶
This solution has the same pinout than previous one.
Third solution (Ironwood)¶
This solution allow solderless testing of your FPGA in tie-bar. This also allows you check your flight model board with a cheaper proto FPGA before doing anything with flight FPGA. Note that this socket needs holes on your PCB and takes some space on your PCB.
