This CHANGELOG contains information for the Imperas RISC-V test framework and tests.
See the ChangeLog.md files in the simulator directories for their changes.
Date 2023-June-26 Release 20230626.0
Added new test suites for the Zicsr instructions making use of the mscratch CSR. These tests are for the instructions and not the CSRs themselves.
Date 2023-March-01 Release 20230228.0
- zvkb is complete with all assertion checks passing.
- zvkg is complete but currently disabled, as the toolchain does not support the latest specification. Previous (lone) instruction (vghmac.vv) was removed from spec and two new instructions added.
- All other zvk* tests are added and passing, but with assertions disabled. Will wait for a more finalized spec and other supporting libraries/examples before implementing assertions and computing of values.
- Removing existing fp16 (SEW==16) from vector tests and adding as separate extensions.
Date 2022-May-30 Release 20220527.0
As a service to our users we have now included the RISC-V International Architectural Compliance Tests as test suites.
This includes: rv32e_m-RVI/C rv32e_m-RVI/E rv32e_m-RVI/M rv32i_m-RVI/C rv32i_m-RVI/F rv32i_m-RVI/I rv32i_m-RVI/K rv32i_m-RVI/M rv32i_m-RVI/Zifencei rv32i_m-RVI/privM rv64i_m-RVI/C rv64i_m-RVI/D rv64i_m-RVI/I rv64i_m-RVI/K rv64i_m-RVI/M rv64i_m-RVI/Zifencei rv64i_m-RVI/privM
Added new test suites for RV32E, RV32EM, RV32EC These are for version 1.9
Date 2022-April-22 Release 20220421.0
Additional PMP tests and updates.
Date 2022-March-10 Release 20220310.0
The initial release of the privilege ISA PMP test suites is now available. This requires a commercial license and like the vector ISA tests suites is configured to the users target device. The suites are targeted at: RV32 priv. versions 1.11, 1.12 (inc. Smepmp) RV64 priv. versions 1.11, 1.12 (inc. Smepmp) Contact [email protected] for more information.
Date 2021-November-16 Release 20211018.0
