Occasional ContributorArria 10 M20k block usage- More block with less memory bits?
Hello I have a design that fits on the Arria 10 GX dev board with chip 10AX11552F4sI1SG which has 2713 M20K blocks. The total memory bits for this design are 36,171,984, all 2713 blocks are used. ...

Occasional ContributorYes I used exactly 2713 blocks. Its really not that difficult. It did not use all of the bits though.
The RAM is implemented in many many ways, from Fifos to instantiated Block RAM IP.
I am not seeing how the RAM would not be implemented in the same way on the new chip. It is just a smaller version of the same Arria 10. It has fewer M20K blocks, not different memory blocks (M10k for example); its not a different family (Cyclone, Stratix, etc.)
I am failing to see how optimization could cause it to need MORE memory blocks when I significantly reduced the required memory bits.
Thanks

Super ContributorWithout seeing the design and how you've organized all the memory, there's really no way to know what happened.
