How can you tell how much CFM (MAX 10 device family) your compressed .pof file takes up if the generated file size is not indicative of the compression ratio?

I saw another post that said you could use the raw binary to know how big your image really is, but that the POF is sized to the device. ​What if you are using a family that doesn't support generati...

Hi SusanB,

To understand the Compress/Decompress algorithm, it is a low level explanation (confidential information). I can't explain to you since it is a confidential info.

The compression ratio for the configuration image should be at least 30% for the device to be able store two configuration images. However, the compression ratio is the design dependent (30% reduction size -- some people can fit into internal flash & some people can fit into the internal flash).

cheers
