8.1i NGDBuild - "Error: 432 - Logical block 'xxxx' with type 'xxx' is unexpanded."

Description

The following error occurs in NGDBuild:

"Error: 432 - Logical block 'xxxx' with type 'xxx' is unexpanded."

Solution

NGDBuild issues this error when it cannot resolve all of the components/modules for the entire design.

For example, suppose you have an HDL design that instantiates black-box modules, and the module description for these black-boxes is contained in an EDIF file. If the EDIF file is not in the macro search path or the project directory, NGDBuild issues this error.

To avoid this problem, verify that the module description file has the correct name and is located in the macro search path or project directory.

Set the macro search path as follows:

ISE

1. Select the top-level source in the Source window.

2. Right-click "Implementation Process" in the Process window and select "Properties."

3. Select the "Translate Properties" tab.

The "Macro Search Path" option is available here.

Design Manager

1. Select Design -> Options.

2. In the Options dialog box, select Implementation -> Edit Options.

3. Select the "Translate" tab.

The "Macro Search Path" option is available here.
