- Infraestrutura de regressões para Synopsys DesignWare DDR-PHY IPPublication . Tucker, Lucas; Gericota, Manuel Gradim de OliveiraVerification regarding integrated circuit designs is an essential step in assuring that the intent of these designs is preserved in their implementation, thus meeting their initial specifications. In this context, regression testing is used in order to assert the working order of newly introduced features in a design and assure previously implemented functionalities have not been hindered. However, regression testing often generates vasts amounts of data, including failures, calling for a process in which to appropriately categorise and prioritise these so as to enable the most effective means of fixing them. This process is known as failure triage. In this project, a developed regression infrastructure for regression running and triaging purposes is presented. This aims to surpass the limitations associated with the previous solution employed at Synopsys, which possesses an in-house nature and, consequently, involves maintenance efforts on the company’s side in order to keep its infrastructure up to date and in working order. The proposed solution involves the application of a standardised regression test execution tool in VC Execution Manager. The developed work was executed alongside this tool, where customisations regarding its user interface were performed in order to provide the same functionalities as with the previous solution. Validation aimed at the developed infrastructure was executed by means of testing the customised interface’s functionalities, upon obtained regression results stemming from regression runs completed with the Execution Manager tool.
