2.1i NGD2VER - ERROR: Portability:90 - Command line error: Switch "-u" is not allowed.


Keywords: NGD2VER, simulation, -u, basut:221, basut

Urgency: Standard

General Description:
When specifying the "-u" option in NGD2VER, the following error is reported:

"ERROR: Portability:90 - Command line error: Switch "-u" is not allowed."


The "-u" was removed as an option in NGD2VER as of Alliance 1.5.19.
The closest option is the "-ne" option (Do not escape names) which will
replace all invalid Verilog characters (including "/") with the underscore
("_") and "not escape" the name with the backslash. For example,

without -ne:
wire \d_in3/INBLOCK/I ;

with -ne:
wire d_in3_INBLOCK_I;

The "-u" option used "_" as the path delimiter instead of "/". This behavior
was very similar to "-ne", so the option was removed.

For more information, please see (Xilinx Solution 2533).
