Errors and warning start with a percent sign (historical heritage from
Digital Equipment Corporation). Some errors or warning have a code
attached, with meanings described below. Some errors also have a filename,
line number and optional column number (starting at column 1 to match GCC).

= Docker Container as Verilator executable
= Verilator Executable Docker Container
This allows you to run Verilator easily as a docker image, e.g.:
The Verilator Executable Docker Container allows you to run Verilator
easily as a docker image, e.g.:
docker run -ti verilator/verilator:latest --version
This is in particular useful to compare against older version or to
check when an issue was introduced.
This will install the container, run the latest Verilator and print
Verilator's version.
You will need to give it access to your files as a volume and fix the
user rights:
Containers are automatically built for all released versions, so you may
easily compare results across versions, e.g.:
docker run -ti verilator/verilator:4.030 --version
Verilator needs to read and write files on the local system. To simplify
this process, use the `verilator-docker` convenience script. This script
takes the version number, and all remaining arguments are passed through to
Verilator. e.g.:
./verilator-docker 4.030 --version
or
./verilator-docker 4.030 --cc test.v
If you prefer not to use `verilator-docker` you must give the container
access to your files as a volume with appropriate user rights. For example
to Verilate test.v:
....
docker run -ti -v ${PWD}:/work --user $(id -u):$(id -g) verilator/verilator:latest --cc test.v
....
The caveat is that it can only access files below the current
directory then, a workaround is to adopt the volume and set
`-workdir`.
This method can only access files below the current directory. An
alternative is setup the volume `-workdir`.
There is a convenience script in this folder that wraps around the
docker calls:
$ verilator-docker 3.922 --version
Verilator 3.922 2018-03-17 rev UNKNOWN_REV
Finally, you can also work in the container by setting the entrypoint
You can also work in the container by setting the entrypoint

You can also use the container to build Verilator at a specific

== Internals
The Dockerfile is pretty straight-forward, it builds Verilator and
removes the tree after that to reduce the image size. It sets a
wrapper script (`verilator-wrap.sh`) as entrypoint. This script calls
Verilator but also copies the verilated runtime files to the `obj_dir`
or the `-Mdir` respectively. This allows the user to build the C++
output with the matching runtime files. The wrapper patches the
generated Makefile accordingly.
The Dockerfile builds Verilator and removes the tree when completed to
reduce the image size. The entrypoint is set as a wrapper script
(`verilator-wrap.sh`). That script 1. calls Verilator, and 2. copies the
Verilated runtime files to the `obj_dir` or the `-Mdir` respectively. This
allows the user to have the files to they may later build the C++ output
with the matching runtime files. The wrapper also patches the Verilated
Makefile accordingly.
There is also a hook defined that is run by docker hub via automated
builds.

clang-format is used to standardize the indentation of the internal C++
code.
For the most part clang-format changes provide good consistency, the two
main exceptions being the indentation of preprocessor directives, and
tables of statements.
Reformatting is generally performed only before other large changes are to
be made to a file. The following files are not yet clang-format clean:
clang-format -i include/verilated.h
clang-format -i include/verilated_dpi.h
clang-format -i include/verilated_fst_c.h
