5.24.11.2 Naming Conventions

• Project names
• Instance names
• Net names
• Port names
• Schematic names
• Stimulus file names
• HDL names

• Do not use any special characters in any of your naming, such as: ~ ! @ # $ % ^ & * ( ) = + { } | \ / < > ? ` ‘ “ “, . or spaces.

• If you want to rip out scalar bits from a bus, use [] for scalar bit naming. For example, Bus[15], Bus[14], …, Bus[0]. If a bus DATA[15:0] is declared in the schematic then you can also use net names DATA5, DATA10 etc. to rip the DATA bus. If net DATA5 is unrelated to the DATA bus then you need to add a letter at the end of the net name, e.g. DATA5N.

Scalar bit Bus1[15] of Bus1[15:0] can be confused with Scalar bit Bus11[5] of Bus11[15:0] during netlist generation.

• If you want to use numbers to distinguish related nets, use numbers followed by letters at the end, for example: NET1N, or Bus1A[15:0].
• Do not use naming “Bus[0:3][0:3]” to implement scalar bits. The second bus dimension is not supported. Instead use: Bus[00], Bus[01]…, Bus[10], Bus[11]….
