The tool does not wait properly for sub-processes (make, make sim, make synth). The tools waits until there is no more output from the sub-process. However, at least under Linux, the process is a terminal, which does not produce any output. The tool therefore does not wait until the sub-process has finished. Maybe Process.waitFor() would be more appropriate?

The application crashes when selecting a newly copied IP core with the following exception:

Setting the platform height or width to a non-numeric value crashes the application. Providing an error message (and ignoring the invalid change) would be more appropriate. The respective exception:

I find it a bit odd that it is not possible to quit/exit the application via the menu. Virtually every GUI application has such an entry in the "File" menu.

When saving before running "make", the tool adds an attribute "class" to the IOs tag in the ip.xml file: . This causes the created XML file to fail validation.

When trying to cancel the creation of a new platform, the tool apparently parses the input, and throws the following exception (without crashing) for an empty input:
