Does the Synthesis Summary Report include the I/O registers from embedded BRAM?

I am specifically interested in the "total registers" value from the report. Does it include the input/output registers that each RAM has or is that not included because those registers always exist even if you do not use the RAM in your design?

    No. The 'Total Registers' value does not include the I/O registers in a RAM (for Cyclone IV anyway). As stated below the 'fitter resource usage summary' section of the '{project}.fit.rpt' report file:

    * Register count does not include registers inside RAM blocks or DSP blocks.

    It's possible this is different for other families. However, I suspect not.
