This scripts also contains Addalways method but the name of clock and reset signal would always be clk and rst followed by a suffix "_n", if negedge was determined, so the original Addalways methods were removed.

Also, the menu entries and keybindings were removed and commandline were added. Other features remains unchanged.

Attention: The eetop_automatic.vim plugin relies on ctags to work, which could be obtained on Github ctas or by package manager if you're using Linux or Mac. Ctags-win32 build binaries could also be obtained on Github ctags-win32. Make sure ctags was in the system path. The plugin automatically calls ctags to generate tags if tags not exits.

Addalways.vim

插件Addalways.vim是从插件automatic-for-Verilog (Vim script)中提取的，本Github页面的Addalways.vim仅包含了AddAlways函数的相关内容。插件最初由arrowroothover开发并在新浪博客上发布。

The Addalways.vim was originally extracted from the plugin automatic-for-Verilog (Vim script), which is developed by arrowroothover and published on his blog.The original project contains a similar features like eetop_automatic.vim, but uses regular expression. This piece script only have the function to detect clock and reset in port and generate always block, for more original features please refer to the blog or Vim scripts page. There is a example:

module example(
	input wire clk, // clock
	input wire rst, // reset
	output wire out
	);

use commandline, :Alpp, then An always block will be added under the cursor, looks like

always @(posedge clk or posedge rst) begin
    if (rst) begin
    end
    else begin
    end
end

note that the clk and rst declaration in put must followed by comments // clock, and // reset to determine the signal. The white space behind the // could be omitted but these inline comments should not followed by any other characters. The name of clock and reset signal could vary.

Other commandline useage:

1. :Alnn stands for add negedge clock and negedge reset;

2. :Alpp stands for add posedge clock and posedge reset;

3. :Alpn stands for add posedge clock and negedge reset;

4. :Alnp stands for add negedge clock and posedge reset;

5. :Alp stands for add posedge clock;

6. :Aln stands for add negedge clock;

7. :Al stands for add always @(*);
