Abstract
A technique for maintaining a transaction history is described. This transaction history includes a sequence of commands or operations in an electronic-design-automation (EDA) environment. For subsets of one or more operations in the sequence of operations, the transaction history includes an associated transaction name, as well as a state of the of the subset, which is open after an initial EDA operation in the subset has been performed and is closed after a last EDA operation in the subset has been performed. This transaction history can be displayed in a window in a graphical user interface, and facilitates undoing and/or rolling back of changes to the data associated with one or more subsets. For example, if an error is detected, roll back of one or more subsets to a known software state or condition prior to the operations in the one or more subsets may be performed without user instructions using the transaction history.
