-## Prerequisites
-To execute tests on CVA6 core, you need a RISC-V toolchain.
-
-Be aware that only gcc 11.1.0 or newer are supported in core-v-verif repository.
-To build and install riscv gcc compiler in local, you can use the following commands :
-
-- `git clone https://github.com/riscv-collab/riscv-gnu-toolchain`
-- `cd riscv-gnu-toolchain`
-- `git clone https://github.com/gcc-mirror/gcc -b releases/gcc-13 gcc-13`
-- ```./configure –prefix:/path/to/installation/directory --with-multilib-generator="rv32e-ilp32e--;rv32i-ilp32--;rv32im-ilp32--;rv32iac-ilp32--;rv32imac-ilp32--;rv32imafc-ilp32f--;rv32imafdc-ilp32d--;rv64i-lp64--;rv64ic-lp64--;rv64iac-lp64--;rv64imac-lp64--;rv64imafdc-lp64d--;rv64im-lp64--;" --with-gcc-src=`pwd`/gcc-13```
-- `make –j32`
-
-These commands will install the riscv gcc 13.1.0 compiler which is the latest version.
-Once running the previous commands, your environment must be updated with :
-
-- `export RISCV=/path/to/installation/directory`
-- `export RISCV_PREFIX=/path/to/installation/directory/bin/riscv64-unknown-`
-- `export RISCV_GCC=/path/to/installation/directory/bin/riscv64-unknown-gcc`
-- `export CV_SW_PREFIX=riscv64-unknown-elf-`
-
-This 4 variables will ensure you use correctly the new gcc compiler you have just installed.
-You will now be able to run the test scripts.
-
-## Test execution
-Run one of the shell scripts:
-
-- `source cva6/regress/dv-riscv-compliance.sh`:
-[riscv-compliance](https://github.com/riscv/riscv-compliance) test suite,
-- `source cva6/regress/dv-riscv-tests.sh`:
-[riscv-tests](https://github.com/riscv/riscv-tests) test suite.
-
-These tests are using [riscv-dv](https://github.com/google/riscv-dv)
-as environment.
-
 ## Verification plan
 Verification plan is available only for vcs tool and located in sim/cva6.hvp, it's used within a modifier to filter out only needed features. Example sim/modifier_embedded.hvp for embedded config.
