3.1i Design Manager - "Create pads from I/O ports" (NGDBuild -a option) does not appear to work


Keywords: ngdbuild, pads, ngd2edif, ngo, ports, create, Design Manager

Urgency: Standard

General Description:
4K/Spartan designs that come in with only a BUFG connected to the port (no
IBUFs or pads) need to have the "Create Pads from I/O Ports" option selected
in the "Translate" tab of the implementation options. However, in certain
circumstances, this option does not appear to work.


The NGDBuild program does not remove the .ngo file when there is a change
in translate options for a particular version/revision; thus, EDIF2NGD does not
run again.

A workaround is to:

- Create a New Version whenever a change in the "Translate" options occurs.


- Remove the .ngo file from the version directory, then rerun the implementation.

A similar situation may occur in Foundation ISE 3.1i; please see (Xilinx Solution 9550).
