Most of them are using UML to draw EA artifacts. First, let up watch a video to get a more tangible understanding of how EA tool can help us establish enterprise architecture.
As we can learn from this video that, the tool can support EA framworks, such as Zachman, it can define and create diagrams for each domain in Zachman framework. It also support inter-domain impact analysis.In this way, it enable the users store and retrieve its artifacts in a more explicit and logical model. EA tools provide guidelines which can help architects better organize its artifacts and documentations.
This video is a demonstration of IBM Rational System Architecture. Even though it named system architecture, it covers all layers from strategy to business, application, system and network infrastructure within an enterprise. This tool is a very good option for EA function. Other good options for EA include alfabet, avolution, BiZZdesign Architect, Casewise Corporate Modeler, OpenText, Troux, ARIS Platform, Mega and Sparx Systems Enterprise Architect.
This is the interface overview of another EA tools ABACUS Modeler.

These tools are powerful and can help architects visualize all needed EA processes.
The institute of Enterprise Architecture Development has published a study in how to assess an EA tool and for real-world selection.

As we can see from this table, we can check the EA tools from different perspective of difference function modular according to our real needs.
Most of these tools have free trial version that can be downloaded directly from their website. The price of these tools varies from each other.The basic package price is around $200 to $300 dollars. They will also provide some extended suite packages.
Another thing I want to mention is that TOGAF has its own EA tool facilitating TOGAF usage also developed by the Open Group. You can access to it by clicking TOGAF 9.1.
