How Illegal Characters are Mapped during CDL Out?

CDL Out searches first for illegal characters, which it maps, as shown in the following table.

First Character	Net	Instance
`$ ; : = \t <space>`	`N`	`X`
`0 to 9`	`N0 to N9`	`X0 to X9`
`A to Z`		`XA to XZ`
`a to z`		`X_A to X_Z`

For example, if $333 is a net name, CDL Out maps it to N333. If $333 is an instance name, CDL Out maps it to X333.

To avoid conflicting instance names, if a name uses less-than and greater-than signs (< and >), CDL Out strips the greater-than sign from the name and replaces the less-than sign with an underscore. For example, the instance named X1<0> would be mapped to X1_0.
