* Initial repository re-organization (#662) Initial attempt to split core from APU. Signed-off-by: MikeOpenHWGroup <mike@openhwgroup.org> Co-authored-by: Jean-Roch Coulon <jean-roch.coulon@invia.fr> Compile `corev_apu` (#667) * Makefile verilates corev_apu * Cleanup README * Fix URL to repo * Cleaned-up Makefile verilates corev_apu Signed-off-by: Mike Thompson <mike@openhwgroup.org> Add extended verification support (#685) * Makefile, riscv_pkg.sv: Select C64A6 or CV32A6 according to variant variable Signed-off-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> * add RVFI tracer and debug support New files: rvfi_pkg.sv, rvfi_tracer.sv, ariane_rvfi.pkg.sv - RVFI ports are added to ariane module - rvfi_tracer.sv is a module added in ariane-testharness.sv - RVFI_TRACE enables RVFI trace generation Co-authored-by: Florian Zaruba <zarubaf@iis.ee.ethz.ch> Signed-off-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> * Move example_tb from cva6 to core-v-verif project Signed-off-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> * Makefile: remove useless rule for vsim Signed-off-by: André Sintzoff <andre.sintzoff@thalesgroup.com> * Makefile: add timescale definition when vsim is used Signed-off-by: André Sintzoff <andre.sintzoff@thalesgroup.com> * Makefile: add vcs support (fix #570) Signed-off-by: André Sintzoff <andre.sintzoff@thalesgroup.com> * rvfi_tracer.sv: fix compilation error raised by vcs Signed-off-by: André Sintzoff <andre.sintzoff@thalesgroup.com> * Makefile: use only 2 threads for verilator when using 4 threads, tests from riscv-compliance and riscv-tests test suite are randomly stucked with rv32ima configuration Signed-off-by: André Sintzoff <andre.sintzoff@thalesgroup.com> * Flist.cva6: cleanup for synthesis workflow Thales synthesis workflow does not manage comments at end of lines Signed-off-by: André Sintzoff <andre.sintzoff@thalesgroup.com> * Support FPGA generation - ariane_xilinx.sv: fix AXI bus expansion - .gitignore, Makefile, run.tcl: fix paths Signed-off-by: André Sintzoff <andre.sintzoff@thalesgroup.com> * riscv-dbg: update to 989389b0 (to support 32-bit CVA6 debug) Signed-off-by: André Sintzoff <andre.sintzoff@thalesgroup.com> * Create cva6_config_pkg to setup 32- or 64-bit configuration According to selected configuration, Makefile calls cv32a6_imac_sv0_config_pkg.sv or cv64a6_imac_sv39_config_pkg.sv Signed-off-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> * Flist, ariane_wrapper.sv: add wrapper to expand rvfi and axi structures needed for dc_shell Signed-off-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> * cv*a6_*_pkg.sv, riscv_pkg.sv: (Fix) Use the camel case for the localparams Signed-off-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> * riscv_pkg.sv: clean-up the cva6_config_pkg import Signed-off-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> * Makefile, ariane.sv: RVFI_TRACE define conditions RVFI port in ariane Signed-off-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> Co-authored-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> Co-authored-by: Florian Zaruba <zarubaf@iis.ee.ethz.ch> * Add lfsr.sv to manifest Signed-off-by: Mike Thompson <mike@openhwgroup.org> * Directory re-organzation * fpga/xilinx/xlnx_axi_dwidth_converter_dm_*: move files (#726) into the new file organisation Signed-off-by: André Sintzoff <andre.sintzoff@thalesgroup.com> * move mmu_sv32 and mmu_sv39, move bootrom, update path (#729) Signed-off-by: sjthales <sebastien.jacq@thalesgroup.com> Co-authored-by: Mike Thompson <mike@openhwgroup.org> Co-authored-by: Jean-Roch Coulon <jean-roch.coulon@thalesgroup.com> Co-authored-by: Florian Zaruba <zarubaf@iis.ee.ethz.ch> Co-authored-by: sébastien jacq <57099003+sjthales@users.noreply.github.com>

PMP
This repository houses a purely combinatorial and parametrizable physical memory protection (PMP) unit.
Warning: The PMP unit does only check the exact byte that is addressed. If the processor wants to load a 8 byte value, then every single byte should get checked. Due to the default granularity of PMPs of 4 bytes, this only comes into play for 8byte RISC-V memory accesses. An easy fix is to increase the granularity to 8 bytes. You can do this by setting the lowest bit of conf_addr_i to 1 if the pmp is in NAPOT mode, or to 0 if the PMP is in TOR mode.
