+# RISC-V compliance check
+
+Verify that Ibex conforms to the RISC-V specification by running a compliance
+check.
+
+Version 2 of [riscv-compliance](https://github.com/riscv/riscv-compliance)
+started to integrate with [RISCOF](https://gitlab.com/incoresemi/riscof) and
+aims to provide the new structure with [version
+3](https://github.com/riscv/riscv-compliance/issues/165#issuecomment-760121860).
+
+Each core provides a Python plugin which handles the required setup,
+compilation and execution step. This plugin is invoked by RISCOF.
+
+A simulation of [Ibex](../riscv_compliance/README.md) is used to execute the
+instruction checks.
+
+RISCOF is not yet finished, some checks will fail and the configuration
+provided by [config.ini](config.ini) will only compare the output from Ibex
+to a fixed reference.
+
+## Run RISCOF RISC-V Compliance
+
+### Requirements
+
+In addition to [steps 0, 1 and
+2](../riscv_compliance/README.md#how-to-run-risc-v-compliance-on-ibex) the
+RISCOF package must be installed:
+
+```sh
+pip3 install --user -U riscof
+```
+
+### Running the checks
+
+```sh
+cd $IBEX_REPO_BASE
+export RISCV_PREFIX=riscv32-unknown-elf-
+export IBEX_SIMULATOR=$PWD/build/lowrisc_ibex_ibex_riscv_compliance_0.1/sim-verilator/Vibex_riscv_compliance
+riscof run --config dv/riscof/config.ini --suite /path/to/riscv-compliance/riscv-test-suite --no-browser
+```
+
+## Additional notes to the current status
+
+### Changing the reference model
+
+In order to compare the results produced by Ibex to another model the file
+`config.ini` must be updated.
+
+To use for example [Sail](https://github.com/rems-project/sail-riscv) update
+and append with:
+
+```
+[RISCOF]
+ReferencePlugin=sail_cSim
+ReferencePluginPath=/path/to/sail_cSim
+
+[sail_cSim]
+pluginpath=/path/to/sail_cSim
+```
+
+### Failing checks
+
+Due to some current restrictions in the test suite some checks fail:
+- Branch and jump fail due to
+ [memory size](https://github.com/riscv/riscv-compliance/issues/157)
+ restrictions.
+- Incorrect selection of
+ [RV64](https://github.com/riscv/riscv-compliance/pull/168) tests.
+- [break](https://github.com/riscv/riscv-compliance/issues/145)
+- [ecall](https://github.com/riscv/riscv-compliance/issues/146)
+- [misalign ldst](https://github.com/riscv/riscv-compliance/issues/147)
+- [misalign jmp](https://github.com/riscv/riscv-compliance/issues/148)
+
+
+### Restrictions
+
+- Due to backwards compatibility riscv-compliance testsuite will report some
+ [warnings](https://github.com/riscv/riscv-compliance/issues/169).
+- Not compatible with
+ [RV32E](https://github.com/riscv/riscv-compliance/issues/142).
+
+
+### Future updates
+
+When the riscv-compliance framework v1 is not longer used, the riscv-compliance
+target can be changed and the memory can be moved to a more sensible location
+(e.g. `0x8000_0000`).
