Yosys environment variables
|
|
===========================
|
|
|
|
``HOME``
|
|
Yosys command history is stored in :file:`$HOME/.yosys_history`. Graphics
|
|
(from `show` and `viz` commands) will output to this
|
|
directory by default. This environment variable is also used in some cases
|
|
for resolving filenames with :file:`~`.
|
|
|
|
``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 :makevar:`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.
