The Max10 does not have enough ram bits to build the full 32768 x 12 ram array.  Some documentation stated that there was more memory than that was actually in the part.  When I tried to infer ram it defaulted to 16384 x 12.  I tried to set the inferred ram size to 4096 x 7 (7 fields of ram).  It still generated 16384 x 12 (4 fields).  The IP catalog has a ram function that let me build a 28672 x 12 array, which I wrapped with verilog to return 0 when to 8 th field is read.  I don't know what happens with writes to that area.
