Quasar RISC-V Core from Lampro Mellon

Configuration

Contents

Name Description
quasar.config Configuration script for core
quasar_config_gen.py Python wrapper to run quasar.config

This script will generate a consistent set of defines/#defines/parameters needed for the design and testbench.
A perl hash (perl_configs.pl) and a JSON format for SweRV-iss are also generated.

This set of include files :

    ./snapshots/<target>
    ├── common_defines.vh                       # `defines for testbench
    ├── defines.h                               # #defines for C/assembly headers
    ├── param.vh                            	# Actual Design parameters
    ├── pdef.vh                             	# Parameter structure definition
    ├── pd_defines.vh                           # `defines for physical design
    ├── perl_configs.pl                         # Perl %configs hash for scripting
    ├── pic_map_auto.h                          # PIC memory map based on configure size
    ├── whisper.json                            # JSON file for swerv-iss
    └── link.ld                                 # Default linker file for tests

While the defines may be modified by hand, it is recommended that this script be used to generate a consistent set.

Targets

There are 4 predefined target configurations: default, default_ahb, typical_pd and high_perf that can be selected via the -target=name option to quasar.config.

Target Description
default Default configuration. AXI4 bus interface.
default_ahb Default configuration, AHB-Lite bus interface
typical_pd No ICCM, AXI4 bus interface
high_perf Large BTB/BHT, AXI4 interface

quasar.config may be edited to add additional target configurations, or new configurations may be created via the command line -set or -unset options.

Run $RV_ROOT/configs/quasar.config -h for options and settable parameters.
