VSCodeHow to configure the verilog environment? The following article recommends three plug-ins to allow VSCode to write verilog smoothly. The three plug-ins can realize code prompts, automatic instantiation, and formatting.
[Recommended learning: vscode tutorial, Programming video】
#Achievable functions:
Plug-in configuration
As described on the Verilog HDL/SystemVerilog plug-in welcome page, supports Ctags function:
ctags, some functions of the old version are not complete enough; Windows can choose the x64 version;
Function display
Supports verilog, SV and other syntax highlighting. 
When the mouse is placed on the signal, a statement will be displayed in the floating box. Ctrl left click and click on the signal name to automatically jump to the declaration. Place the cursor at the signal, right-click and select View Definition (the shortcut keys can be bound by yourself). You can expand the code at the declaration here. It is very convenient to modify the declaration without having to jump back and forth. 
##Achievable functions:
Automatically generate testbench
shift ctrl p input testbench, you can directly generate tb. Then copy it in the terminal.
The effect is very good
, and it also supports a wide range of customized formatting parameters. Personally, I think it is easier to use than verilog format.
Achievable functions
Automatically format filesCustom parameter setting table##verible-verilog-format: usage: bazel- bin/verilog/tools/formatter/verible-verilog-format [options]
Flags from common/formatting/basic_format_style_init.cc:
--column_limit (Target line length limit to stay under when formatting.);
default: 100;
--indentation_spaces (Each indentation level adds this many spaces.);
default: 2;
--line_break_penalty (Penalty added to solution for each introduced line
break.); default: 2;
--over_column_limit_penalty (For penalty minimization, this represents the
baseline penalty value of exceeding the column limit. Additional penalty
of 1 is incurred for each character over this limit); default: 100;
--wrap_spaces (Each wrap level adds this many spaces. This applies when the
first element after an open-group section is wrapped. Otherwise, the
indentation level is set to the column position of the open-group
operator.); default: 4;
Flags from external/com_google_absl/absl/flags/parse.cc:
--flagfile (comma-separated list of files to load flags from); default: ;
--fromenv (comma-separated list of flags to set from the environment [use
'export FLAGS_flag1=value']); default: ;
--tryfromenv (comma-separated list of flags to try to set from the
environment if present); default: ;
--undefok (comma-separated list of flag names that it is okay to specify on
the command line even if the program does not define a flag with that
name); default: ;
Flags from verilog/formatting/format_style_init.cc:
--assignment_statement_alignment (Format various assignments:
{align,flush-left,preserve,infer}); default: infer;
--case_items_alignment (Format case items:
{align,flush-left,preserve,infer}); default: infer;
--class_member_variable_alignment (Format class member variables:
{align,flush-left,preserve,infer}); default: infer;
--compact_indexing_and_selections (Use compact binary expressions inside
indexing / bit selection operators); default: true;
--distribution_items_alignment (Aligh distribution items:
{align,flush-left,preserve,infer}); default: infer;
--enum_assignment_statement_alignment (Format assignments with enums:
{align,flush-left,preserve,infer}); default: infer;
--expand_coverpoints (If true, always expand coverpoints.); default: false;
--formal_parameters_alignment (Format formal parameters:
{align,flush-left,preserve,infer}); default: infer;
--formal_parameters_indentation (Indent formal parameters: {indent,wrap});
default: wrap;
--module_net_variable_alignment (Format net/variable declarations:
{align,flush-left,preserve,infer}); default: infer;
--named_parameter_alignment (Format named actual parameters:
{align,flush-left,preserve,infer}); default: infer;
--named_parameter_indentation (Indent named parameter assignments:
{indent,wrap}); default: wrap;
--named_port_alignment (Format named port connections:
{align,flush-left,preserve,infer}); default: infer;
--named_port_indentation (Indent named port connections: {indent,wrap});
default: wrap;
--port_declarations_alignment (Format port declarations:
{align,flush-left,preserve,infer}); default: infer;
--port_declarations_indentation (Indent port declarations: {indent,wrap});
default: wrap;
--port_declarations_right_align_packed_dimensions (If true, packed
dimensions in contexts with enabled alignment are aligned to the right.);
default: false;
--port_declarations_right_align_unpacked_dimensions (If true, unpacked
dimensions in contexts with enabled alignment are aligned to the right.);
default: false;
--struct_union_members_alignment (Format struct/union members:
{align,flush-left,preserve,infer}); default: infer;
--try_wrap_long_lines (If true, let the formatter attempt to optimize line
wrapping decisions where wrapping is needed, else leave them unformatted.
This is a short-term measure to reduce risk-of-harm.); default: false;
Flags from verilog/parser/verilog_parser.cc:
--verilog_trace_parser (Trace verilog parser); default: false;
Flags from verilog/tools/formatter/verilog_format.cc:
--failsafe_success (If true, always exit with 0 status, even if there were
input errors or internal errors. In all error conditions, the original
text is always preserved. This is useful in deploying services where
fail-safe behaviors should be considered a success.); default: true;
--inplace (If true, overwrite the input file on successful conditions.);
default: false;
--lines (Specific lines to format, 1-based, comma-separated, inclusive N-M
ranges, N is short for N-N. By default, left unspecified, all lines are
enabled for formatting. (repeatable, cumulative)); default: ;
--max_search_states (Limits the number of search states explored during line
wrap optimization.); default: 100000;
--show_equally_optimal_wrappings (If true, print when multiple optimal
solutions are found (stderr), but continue to operate normally.);
default: false;
--show_inter_token_info (If true, along with show_token_partition_tree,
include inter-token information such as spacing and break penalties.);
default: false;
--show_largest_token_partitions (If > 0, print token partitioning and then
exit without formatting output.); default: 0;
--show_token_partition_tree (If true, print diagnostics after token
partitioning and then exit without formatting output.); default: false;
--stdin_name (When using '-' to read from stdin, this gives an alternate
name for diagnostic purposes. Otherwise this is ignored.);
default: "";
--verbose (Be more verbose.); default: false;
--verify_convergence (If true, and not incrementally formatting with
--lines, verify that re-formatting the formatted output yields no further
changes, i.e. formatting is convergent.); default: true;Try --helpfull to get a list of all flags or --help=substring shows help for
flags which include specified substring in either in the name, or description or
path.
插件配置
如果是windows，systemverilogFormatter.veribleBuild设置为win64
systemverilogFormatter.commandLineArguments可以自定义格式化参数，下面放上我自己用的参数，可以实现大部分常用代码段实现对齐。
--indentation_spaces=4 --named_port_alignment=align --ort_declarations_alignment=align --module_net_variable_alignment=align
如何使用？如何格式化？
和vscode内置格式化一样，直接shift ctrl f就可以格式化文件，ctrl k可以格式化选定内容。
值得注意的是，由于这个插件也是在完善中，还是存在部分问题的。
比如else不会换行。
比如，存在语法问题，或者不能识别语法的时候，格式化会使用不了。这里我将最后一个端口加上","就不能格式化了。
