The tests are grouped based on the different extension subsets of the RISC-V unprivileged ISA. The tests strictly follow the Test format specification.
Directory names postfixed with "_unratified" indicate that tests for extensions that have not yet been ratified by RVI.
The coverage report (in html format) of the tests available in this suite is generated through RISCOF and is available here: Coverage Report.
These tests have been generated using the open source Compatibility Test Generator from InCore Semiconductors available at: CTG.
The reference signatures are generated using SAIL or SPIKE.
Test directories with the "_unratified" post-fix indicate test-suites for extensions which have not been ratified (but are stable and near ratification)
