During my MS studies and working as researcher in the Integrated Circuits & Systems Lab (ICSL) at Shahed University, I developed an electronic design automation tool named JPAD for designing and simulating analogue IC circuits. The program was purely developed in Java. The source code of this tool can be found in the source directory of this repository.
Licence: Note that the code can be changed and reused as long as you keep the copyright inside and at the beginning of every Java file in the source directory unchanged. If this tool is used in a research project that ends up with a publication, it should be cited as Alireza Poshtkohi and M. B. Ghaznavi-Ghoushchi, A Java-based EDA tool for analogue integrated circuit design, https://github.com/poshtkohi/jpad.
Two snapshots of the program are shown below
