 2) Multi file IP
 
-The multi file IP is kept in sub directories in the top level ip_<device_name>
-directory to be able to keep the generated files together.
+The multi file IP is kept in sub directories in the top level ip_<device_name>/<ip_name> directory to be able to keep the generated files together:
 
+  ip_<device_name>/<ip_name>/              -- source files (all in SVN)
+                   <ip_name>/generated/    -- generated files (may also be committed in SVN)
+
+The source files are kept in the <ip_name> directory. The generated files are kept in a <ip_name>/generated/ directory. The MegaWizard variation file
+is typically a <ip_name>.vhd VHDL file is the top level file and that also is used by the MegaWizard to generated the IP. The generate_ip.sh script
+can be run to generate the IP, usage:
+
+  ./generate_ip.sh
+
+The generate_ip.sh script first copies the MegaWizard variation file in the 'generated' output dir, because:
+
+  1) setting the output dir is not an option in the MegaWizard
+  2) The MegaWizard overwrites the variation file sometimes - we don't want that as it could be hand-modified with e.g. added generics
+  
+The generated files for Quartus v11.1 that are needed for simulation and synthesis may also be committed in SVN, so it is not necessary to run this
+generate_ip.sh script again. Files that are not needed should better not be committed in SVN. The advantage of only committing what is needed is that
+it is more clear what is needed and that it may save substantial disk space in the repository and at local at each check out. The disadvantage of
+committing only what is needed may be that it takes some effort to find out what is needed. If the size/amount of files that are not needed is
+relatively small then committing all generated files is fine too.
+
+For simulation the MegaWizard also generates a msim_setup.tcl script. A stripped down version of this msim_setup.tcl script is made manually and
+kept in compile_ip.tcl. This compile_ip.tcl only compiles what is needed and is made available in the Modelsim project file via the
+modelsim_compile_ip_files key in the hdllib.cfg. The 'mk' command automatically also executes the compile_ip.tcl before it compiles any other HDL
+in the library.
