The original Rocket chip repository provides a thorough test suite for the RISC-V ISA (riscv-tools/riscv-tests/isa). All tests are written in assembly.

A new test case is provided in riscv-tools/riscv-tests/isa/rv64si/ltag.S

More complicated tests can be found in riscv-tools/lowrisc-tag-tests/tests:

Running the tests

The tests can be run using the proxy kernel or within RISC-V Linux. You can generate the proxy kernel executables using the Makefile included (simple type make) or make linux to generate binaries for RISC-V Linux.

The detailed steps necessary to run the tests in simulation or on the FPGA are described in the subsequent sections of the tutorial.
