Orcad simulation: "Translation failed" when using "Convert XNF to VHDL"


Keywords: Orcad, simulate, translation, convert xnf to vhdl

Urgency: standard

General Description: When using Simulate's Convert XNF to VHDL
command a user may get the error message: "translation failed"
from the Tools menu. The reason for the error may not be clear.


One possible cause of this error is the use of non-alphanumeric
characters as part of a signal name in your VHDL source code.
For example, Xilinx accepts non-alphanumeric characters such
as tildes, slashes, plus signs, minus signs, asterisks, and so on
in signal names, but Simulate does not.

To fix the problem, follow these steps:

1.Open the design in Capture, replace non-alphanumeric characters
in signal names with alphanumeric characters, then save the design.

2.Use Xilinx software to generate a new .XNF file from the design.

3.From Simulate's Tools menu, choose Convert XNF to VHDL and
use your newly generated .XNF file.
