After the download is complete, drag the downloaded .jar file to an open instance of Astah. A pop-up will appear asking you to confirm installation. Choose [Yes]. If the pop-up below opens, restart Astah.
If [generate Sequence diagram] appears under [Plugin], your installation is complete.
How to Use
Run the command below in the VDMTools interpreter. This exports calllog.txt. >> set calllog
Open calllog.txt, keep the part you want to convert into a sequence diagram, delete the rest, and save the file. A sample is shown below.
In Astah, go to [Plugin] – [generate Sequence diagram] and select the calllog.txt file.
A sequence diagram is generated from the call log exported from VDMTools.
