Problem Title:
F1.4 Schematic Capture: Valid characters for signal and instance names
Problem Description:
Urgency: Normal
General Description:
In F1.4 Schematic Capture, if a character other than A-Z, a-z, 0-9, _, $,
is used to name a net, the following warning appears:
"The following character(s) may be illegal for target vendor
software. Do you want to continue?"
What does this mean? Where is the naming convention
documented?
Solution 1:
Non-standard characters may be replaced by other characters when the
netlist is translated. The most common replacement character used is
the underscore (_). This is especially troubling when doing a back-annotated
simulation, since the netnames will now be different from the original design. Non-standard charact
ers can also cause problems in
the downstream tools.
Therefore, it is advisable to not use any non-standard characters to name
nets and instances in your design. Only use A-Z, a-z, 0-9, _
