ALE Verilog/SystemVerilog Integration *ale-verilog-options*
|
|
|
|
|
|
===============================================================================
|
|
ALE can use six 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`
|
|
|
|
Yosys
|
|
Using `ysoys -Q -T -p 'read_verilog'`
|
|
|
|
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.

===============================================================================
|
|
iverilog *ale-verilog-iverilog*
|
|
|

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*

|
|
*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*
|
|

|
|
*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'.

yosys *ale-verilog-yosys*
|
|
|

*b:ale_verilog_yosys_executable*
|
|
Type: |String|

Default: `'yosys'`
|
|
|
|
This variable can be changed to the path to the 'yosys' executable.

Type: |String|
|
|
Default: `'-Q -T -p ''read_verilog %s'''`
|
|
|
|
This variable can be changed to modify the flags/options passed to 'yosys'.
|
|
By default, Yosys is an interative program. To obtain linting functionality,
|
|
the `'read_verilog'` command is used.
