How can I determine M20K number from block memory bits value?

I compiled a design, The compilation failed in fit.

in fit report section "Fitter Resource Utilization by Entity", I found that M20K field contains N/A, and block memory bits = 640, as shown below:

I need to determine M20K number, is it possible to determine it from "block memory bits" value?

 

Note: the total M20K blocks used is estimated in Quartus fit report section Fitter Resource Usage Summary:

 

Thanks.

Re: How can I determine M20K number from block memory bits value?

You will need to run until fitter finished in order to see this report. You can also estimate the M20k number by looking into the synthesis report of the block memory bits / 20. You may refer to https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/arria-v/av_5v2.pdf table 2-1 as an example.
