Creating HDL Text Modules, страница 71

                                                            Analysis of pure HDL sources in this form is quite difficult and requires skills

                                                            These files can be converted into diagram

                                                            F.3 Diagram from HDL

First you will convert bjack.vhd

•  Use the Code2Graphics Conversion Wizard...  option from the Tools menu.
The Code2Graphics application will be invoked

•  Now you can select one of three options:
- Crate a new design…
- Add to current design…
- Do not add to any design…
Select second option – this will add created diagram to your design and click Next

F.4 Diagram from HDL

•  Press the Add button

•  Open the bjack.vhd file

•  Press the Settings button

                                                                      F.5 Diagram from HDL

There are several options:

•  Multiple pages – allows to generate multiple pages block diagram

•  Diagram options – you are able to set which information about symbols should be visible on diagram

•  VHDL special symbols – you are able to set options for generating VCC and GND symbols.

Set options

Press the OK button

Now you will convert bjack_c

•  Use the Code2Graphics Conversion Wizard...  option from the Tools menu once more

•  Choose to add files to current design again and advance using Next button

                                                             F.10 Diagram from HDL

•  Press the Add… button

•  Open the  bjack_c.vhd file

•  Press the Settings button
