Yosys environment variables
|
||
|
|
===========================
|
||
|
|
|
||
|
|
``HOME``
|
||
|
|
Yosys command history is stored in ``$HOME/.yosys_history``. Graphics (from
|
||
|
|
:cmd:ref:`show` and :cmd:ref:`viz` commands) will output to this directory by
|
||
|
|
default. This environment variable is also used in some cases for resolving
|
||
|
|
filenames with ``~``.
|
||
|
|
|
||
|
|
``PATH``
|
||
|
|
May be used in OpenBSD builds for finding the location of Yosys executable.
|
||
|
|
|
||
|
|
``TMPDIR``
|
||
|
|
Used for storing temporary files.
|
||
|
|
|
||
|
|
``ABC``
|
||
|
|
When compiling Yosys with out-of-tree ABC using ``ABCEXTERNAL``, this
|
||
|
|
variable can be used to override the external ABC executable.
|
||
|
|
|
||
|
|
``YOSYS_NOVERIFIC``
|
||
|
|
If Yosys was built with Verific, this environment variable can be used to
|
||
|
|
temporarily disable Verific support.
|
||
|
|
|
||
|
|
``YOSYS_COVER_DIR`` and ``YOSYS_COVER_FILE``
|
||
|
|
When using code coverage, these environment variables control the output file
|
||
|
|
name/location.
|
||
|
|
|
||
|
|
``YOSYS_ABORT_ON_LOG_ERROR``
|
||
|
|
Can be used for debugging Yosys internals. Setting it to 1 causes abort() to
|
||
|
|
be called when Yosys terminates with an error message.
