SOF file won't compress into a POF file

I have been slowly developing my FPGA code, and up until now, I have had no trouble fitting it into a POF file, but now I'm getting this message. I'm developing for a Cyclone V (5CEFA9U19I7)...

Hi BaronBlackhawk,


Just wanted to check, may I know that you have properly done the connection as per mentioned in the user guide as below?


Please refer: Cyclone V Device Handbook - Intel page 270

You also may enable Compression Before Design Compilation

To enable compression before design compilation, follow these steps:

1. On the Assignment Menu, click Device.

2. Select your Cyclone V device and then click Device and Pin Options.

3. In the Device and Pin Options window, select Configuration under the Category list and turn on

Generate compressed bitstreams.


Please let me know if this works for you. Thank you.


Regards,

Fakhrul

    I have done this. This had already been set. So far I've had the best luck with reducing the number of hardware multipliers I'm using.

    The best I can tell, the amount of compression the tools provide isn't sufficient for all designs that should fit in the Cyclone. I don't know if I consider this a resolution to my problem. I have redesigned my filters to use fewer multipliers and I will see if it fits.
