![srdl2sv logo](images/srdl2sv_logo.gif) # Introduction srdl2sv is a [SystemRDL 2.0](https://www.accellera.org/images/downloads/standards/systemrdl/SystemRDL_2.0_Jan2018.pdf) to (synthesizable) [SystemVerilog](https://ieeexplore.ieee.org/document/8299595/versions) compiler. The tool is based on based on [SystemRDL/systemrdl-compiler](https://github.com/SystemRDL/systemrdl-compiler). ## ⚠️ Non-production ready Warning! This software is still under development and not yet ready for use in production. # Getting started ## Installation ## Compiling your first RDL The argument that is required to get started is the location of the SystemRDL file that contains the root address map. The compiler will generate a seperate SystemVerilog module for each address map it encounters in the code. Thus, if address maps are instantiated within other address maps, these will be packed into a seperate module. To compile a file called `example_addrmap.rdl`, simply run: ``` srdl2sv example_addrmap.rdl ``` By default, the compiler will create a directory called `srdl2sv_out` and dump `example_addrmap.sv` with the actual RTL and a log file that contains `INFO`-level logging into this directory. To change the logging level, use `--file_log_level` like shown below: ``` srdl2sv example_addrmap.rdl --stream_log_level {DEBUG,INFO,WARNING,ERROR,CRITICAL,NONE} ``` Similarly, to change the default log level of the output to the shell, which is `WARNING`, use `--stream_log_level` like shown below: ``` srdl2sv example_addrmap.rdl --stream_log_level {DEBUG,INFO,WARNING,ERROR,CRITICAL,NONE} --file_log_level {DEBUG,INFO,WARNING,ERROR,CRITICAL,NONE} ``` If the RDL file includes other RDL files, the directories that contain these files must be passed to the compiler as follows: ``` srdl2sv example_addrmap.rdl --search_paths SEARCH_PATHS [SEARCH_PATHS ...] ``` ## Using the generated RTL ## Help function A comprehensive help function of the tool can be invoked by running `srdl2sv --help`. ``` usage: main.py [-h] [-o OUT_DIR] [-d SEARCH_PATHS [SEARCH_PATHS ...]] [-r] [-x] [-e] [--stream_log_level {DEBUG,INFO,WARNING,ERROR,CRITICAL,NONE}] [--file_log_level {DEBUG,INFO,WARNING,ERROR,CRITICAL,NONE}] [--real_tabs] [--tab_width TAB_WIDTH] IN_RDL [IN_RDL ...] SystemRDL 2 SystemVerilog compiler positional arguments: IN_RDL Location of RDL file(s) with root addrmap. optional arguments: -h, --help show this help message and exit -o OUT_DIR, --out_dir OUT_DIR Define output directory to dump files. If directory is non-existent, it will be created. (default: ./srdl2sv_out) -d SEARCH_PATHS [SEARCH_PATHS ...], --search_paths SEARCH_PATHS [SEARCH_PATHS ...] Point to one (or more) directories that will be searched for RDL files. -r, --recursive_search If set, the dependency directories will be searched recursively. -x, --disable_sanity Disable sanity checks or components. This might speed up the compiler but is generally not recommended! -e, --disable_enums Disable enumeration generation. This will prevent the compiler from generating packages and it will prevent it from using enums in the port list. --stream_log_level {DEBUG,INFO,WARNING,ERROR,CRITICAL,NONE} Set verbosity level of output to shell. When set to 'NONE', nothing will be printed to the shell. (default: WARNING) --file_log_level {DEBUG,INFO,WARNING,ERROR,CRITICAL,NONE} Set verbosity level of output to log-file. When set to 'NONE', nothing will be printed to the shell. (default: INFO) --real_tabs Use tabs, rather than spaces, for tabs --tab_width TAB_WIDTH Define how many tabs or spaces will be contained in one level of indentation. (default: 4) ``` # Contributing # Limitations - [Any limitations to the systemrdl-compiler](https://systemrdl-compiler.readthedocs.io/en/latest/known_issues.html) also apply to the SystemRDL2SystemVerilog compiler. - Depth of a hierarchy is limited to 26 levels.
