How to reduce the LE countes in my design ?

[Altera_Forum]

Dear Forum: 

 I use the DE10-Lite with Max10 FPGA board to run the FLAC compressor encoder hardcore ; but happened fail as blow information ,  https://dl-mail.ymail.com/ws/download/mailboxes/@.id==VjJ-kVMRcIr8U5H6UEl-BitowlisPW27x2JEXrheABgbuAdN66u3DaeSShoDgxrEsrHm9DQuTRucevTurU7WzSkBBg/messages/@.id==AI_PexsAABSPWNkjdANLwJcsTyw/content/parts/@.id==2/raw?appid=YahooMailNeo&ymreqid=6f92fda4-1c84-87ba-0196-a80023010000&token=zitEzqOML3j84e6ealFTT5U7-km5qEQF52lp7AcCuBZpFTVayDSiwS6mZ9IbZMNvOo...     error code: Info (171121): Fitter preparation operations ending: elapsed time is 00:07:47  Info (14896): Fitter has disabled Advanced Physical Optimization because it is not supported for the current family.  Info (170189): Fitter placement preparation operations beginning  Error (170011): Design contains 146846 blocks of type combinational node.

If the design is too big, then you need to change the design, or change the FPGA. 

I cant really tell you what you need, as I have no idea what the project is or what the requirements are. That is your job to research...

I would start by targeting a larger device so that the design will compile. Then you can look at fitter reports to see where the gates are being used and figure out if there's anything you can do about it. If the encoder is IP that you purchased then there's probably not much you can do. But if that's the case then the IP vendor should be able to give you guidance on which FPGA family and device you should target. If this is your own IP then it's all on you to find a fit.
