TCL command in Libero SOC [Microsemi] to generate the IP cores
This is an old question, but I couldn't find this information anywhere so I think it's helpful to add it here!

In Libero you can go to File -> Export Script File... and export a Tcl script with the commands that have been run in your current project - importing files, creating IP etc. If you create an IP core and then export the script file, you will see the basic building block for instantiating the IP, although none of your configuration options will be shown.

The following is what I got for instantiating a BIBUF, for example. Almost there, but not quite!

create_design -id {Actel:SgCore:IO:1.0.101} -design_name {sram_bidir} -config_file {} -params {} -inhibit_configurator 0

You can see the -params{} field in this command. This is what you use to configure the core, but annoyingly it's always empty in the exported script! 

At least for the cores I have used, I have not found any documentation on the parameter names. Instead, I navigate my file explorer to the component definition in the Libero project directory structure:
e.g.


  [project's root folder] -> component -> work -> sram_bidir


In this folder there is a ".cxf" file, which is basically an XML file with all the core's parameters defined. The parameters for the core are those contained in the &lt;configurableElement&gt; tag e.g. for the BIBUF: 

&lt;configurableElement referenceId="IO_TYPE" value="BIBUF"/&gt;

This information can then be used to configure the core in the Tcl command as follows:

create_design -id {Actel:SgCore:IO:1.0.101} -design_name {sram_bidir} -config_file {} -params {IO_TYPE:BIBUF} -params {WIDTH:32} -inhibit_configurator 0

It's a bit trial and error, but I have gotten several cores working this way.
