Eric, I appreciate your willingness to dig further to help, but my
question was how I could check the block ram mapping of my design
which I thought it was quite generic, and I would expect answers, such
as, look at somewhere or look for something in the synthesis log file,
or open fpga editor and look for instantiations of primitives. BTW, I
suppose most of us in this group do not work for ourselves, only lazy
university students would post their entire project and let somebody
else do the work for them. Thanks!
