ALE Verilog/SystemVerilog Integration *ale-verilog-options*
===============================================================================
ALE can use five different linters for Verilog HDL:
HDL Checker
Using `hdl_checker --lsp`
iverilog:
Using `iverilog -t null -Wall`
verilator
Using `verilator --lint-only -Wall`
ModelSim/Questa
Using `vlog -quiet -lint`
Vivado
Using `xvlog`
By default, both 'verilog' and 'systemverilog' filetypes are checked.
You can limit 'systemverilog' files to be checked using only 'verilator' by
defining 'g:ale_linters' variable:
>
au FileType systemverilog
\ let g:ale_linters = {'systemverilog' : ['verilator'],}
<
===============================================================================
General notes
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.
HDL Checker is an alternative for some of the issues described above. It wraps
around ghdl, Vivado and ModelSim/Questa and, when using the latter, it can
handle mixed language (VHDL, Verilog, SystemVerilog) designs.
===============================================================================
hdl-checker *ale-verilog-hdl-checker*
See |ale-vhdl-hdl-checker|
===============================================================================
iverilog *ale-verilog-iverilog*
No additional options
===============================================================================
verilator *ale-verilog-verilator*
g:ale_verilog_verilator_options *g:ale_verilog_verilator_options*
*b:ale_verilog_verilator_options*
Type: |String|
Default: `''`
This variable can be changed to modify 'verilator' command arguments
For example `'-sv --default-language "1800-2012"'` if you want to enable
SystemVerilog parsing and select the 2012 version of the language.
===============================================================================
vlog *ale-verilog-vlog*
g:ale_verilog_vlog_executable *g:ale_verilog_vlog_executable*
*b:ale_verilog_vlog_executable*
Type: |String|
Default: `'vlog'`
This variable can be changed to the path to the 'vlog' executable.
g:ale_verilog_vlog_options *g:ale_verilog_vlog_options*
*b:ale_verilog_vlog_options*
Type: |String|
Default: `'-quiet -lint'`
This variable can be changed to modify the flags/options passed to 'vlog'.
===============================================================================
xvlog *ale-verilog-xvlog*
g:ale_verilog_xvlog_executable *g:ale_verilog_xvlog_executable*
*b:ale_verilog_xvlog_executable*
Type: |String|
Default: `'xvlog'`
This variable can be changed to the path to the 'xvlog' executable.
g:ale_verilog_xvlog_options *g:ale_verilog_xvlog_options*
*b:ale_verilog_xvlog_options*
Type: |String|
Default: `''`
This variable can be changed to modify the flags/options passed to 'xvlog'.
