ALE VHDL Integration *ale-vhdl-options*
|
|
|
|
|
|
===============================================================================
|
|
ALE can use three different linters for VHDL:
|
|
|
|
iverilog:
|
|
Using `iverilog -t null -Wall`
|
|
|
|
ModelSim/Questa
|
|
Using `vcom -2008 -quiet -lint`
|
|
|
|
Vivado
|
|
Using `xvhdl --2008`
|
|
|
|
Note all linters default to VHDL-2008 support. This, and other options, can be
|
|
changed with each linter's respective option variable.
|
|
|
|
Linters/compilers that utilize a "work" directory for analyzing designs- such
|
|
as ModelSim and Vivado- can be passed the location of these directories as
|
|
part of their respective option strings listed below. This is useful for
|
|
holistic analysis of a file (e.g. a design with components, packages, or other
|
|
code defined external to the current file as part of a larger project) or
|
|
when wanting to simply pass an alternative location for the auto-generated
|
|
work directories (such as '/tmp') so as to not muddle the current directory.
|
|
Since these type of linters often use this work directory for holding compiled
|
|
design data as part of a single build process, they sometimes cannot handle
|
|
the frequent, asynchronous application launches when linting while text is
|
|
changing. This can happen in the form of hangs or crashes. To help prevent
|
|
this when using these linters, it may help to run linting less frequently; for
|
|
example, only when a file is saved.
