SYNOPSYS CoreTools VW 2024.9
Synopsys' CoreTools consists of the following:
coreBuilder : This tool may be used to package a third party IP/Component into synopsys's environment.
It may be used to genearate the IP-XACT view of the IP/Component.
It may be used to generate the IP/component's  'coreKit' , a synopsys database, which is used in coreTools.
This will then allow the user to use the packaged third party IP, with coreTools.

coreConsultant : This tool may be used to configure an instance of the IP, define its parameters, and run
simulation on the same. The o/P of this tool may be a configured RTL of the IP/component and a Testbench.

coreAssembler : This tool is used to 'assemble' a subsystem.

This tutorial is about coreAssembler.
coreAssembler may act in certain circumstances as a super set of coreConsultant.
That is to say coreAssembler can do a few things that coreConsultant can do.
But it is to be noted that coreAssembler is not a complete superset.

What is coreAssembler used for:
coreAssembler is used to build subsystems.
It allows the user to assemble IPs, make connections and dump out the Subsystem RTL.
Under some circumstances it will also dump out a Testbench environment.
It also allows the user to synthesize the Subsystem.
However the scope of this tutorial is to be able to help the user build a Subsystem RTL
