I used to see this using older versions of SOPC Builder (7.1-7.2). I use 9.0 these days so I haven't seen this issue in a while. Mapper is being called to elaborate the signals and parameters. Make sure that you don't have any parameters that are based on other parameters that affect the top level module signal widths and this breaks mapping rules.

Once you have a component .tcl file saved you can manually edit it and set the parameters which don't affect elaboration to 'affects_elaboration false' which should speed things up. To learn more about the underlining .tcl commands you can refer to the Quartus II handbook, volume 4 (SOPC Builder), chapter 7.
