Let's see a example. Drag & Drop "do_file_test.vcd" to Veritak icon.
Then ,
Utility => Read Do File... =>"do_file_test_vcd.do"

This ".do file" contains the format for WaveformView.

Double Click the line of. .do_file_test_vcd.do(1)::start reading wavefile format.
Since ".do file"is text file, you can edit the format by text editor.

Notes:

• prefix @ shows the signal is vcd
• prefix # shows the signal is grouped signal by vcd
• prefix + shows the signal is grouped signal.
• Keyword "gwave" shows the signal is grouped signal followed by "sub" statement

Let's look at the difference between project file and do file.

Load Verilog Project "do_file_test.vtakprj
Project file can contain all the information for waveform view, such as format ,cursor position,color,... and other setting information of compiler.

Utility => Read Do File... =>"do_file_test.do"
In "do file ", It saves only wavefile format.Enum function is not supported.

Using "Do file" multiple waveformviews including vcd format can be viewed.
Utility => Read Do File... =>"do_file_test_vcd.do"
