Add script to generate technology-dependent primitives on the fly Some primitives are intended to be implemented in a technology-specific way, e.g. differently for Xilinx or Altera FPGAs. Which implementation is to be used can be specified at synthesis time. Target-specific implementations are collected in "technology libraries", or "techlibs". When writing code, only "abstract primitives" are used. These are then implemented by a techlib. Currently, all techlibs are part of the OpenTitan repository, and all abstract primitives are hand-crafted. This commit adds a script to auto-generate these abstract primitives. The script is to be used as FuseSoC generator. Note that the script currently is in a rather "rough" form. The SystemVerilog "parsing" is done using a regex instead of a proper parser, and speed isn't great either. Signed-off-by: Philipp Wagner <phw@lowrisc.org>
OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can either access it online or build it locally by following the steps below.
$ sudo apt install curl python3 python3-pip $ pip3 install --user -r python-requirements.txt
$ ./util/build_docs.py --preview
This compiles the documentation into ./build/docs and starts a local server, which allows you to access the documentation at http://127.0.0.1:1313.
