Answers Database NGD2VER 2.1: ERROR: Portability:90 - Command line error: Switch "-u" is not allowed. Record #6482 Product Family: Software Product Line: FPGA Implementation Product Part: ngd2ver Product Version: 2.1i Problem Title: NGD2VER 2.1: ERROR: Portability:90 - Command line error: Switch "-u" is not allowed. Problem Description: Urgency: Standard When specifying the "-u" option in NGD2VER, the following error is reported: ERROR: Portability:90 - Command line error: Switch "-u" is not allowed. Solution 1: 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 to 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 pathdelimiter instead of "/". This behavior was very similar to "-ne", and thus the option was removed. Please see (Xilinx Solution 2533) End of Record #6482 - Last Modified: 11/17/99 11:34
