  - Tools/Platform Designer

  - In system view:
    . remove components
    . add components from Uniboard library (double click avs_common_mm or use green +)
-     use qsys_unb2c_test_ prefix in component name ip file, but rename component without prefix
+     set parameter g_addr_w for avs_common_mm
+     use qsys_unb2c_test_ prefix in component name ip file, but then rename component without prefix in System view window
+     for sdp use prefix: qsys_lofar2_unb2c_sdp_station_
+   . connect busses via the graphical dots, similar as for other ports
    . use periperal names that match the upe_gear default name + instance scheme
      double click export name to change it, none for default
    . System/assign base addresses
      System/assign interrupt numbers

    . copy component from Generate/Show instance template --> qsys_unb2c_test_pkg.vhd
    . no need to generate HDL
  - Ignore warning about avs_eth_0 IP parameterization
