Spectre

Described below are the name mapping variables for Spectre Direct netlister:

Variable	Description
hnlSpectreMapInstInName	List of characters that are invalid internal to an inst name.
hnlSpectreMapNetInName	List of characters that are invalid internal to a net name.
hnlSpectreMapInstFirstChar	List of characters that are invalid for the first character of a inst name.
hnlSpectreMapNetFirstChar	List of characters that are invalid for the first character of a net name.

Default Behavior

• Replace the invalid characters by their escaped equivalent.
• If the invalid character is a number, replace it by an underscore followed by the number.

Customization

• You can directly set any/all of the above mentioned variables to customize the character substitution and therefore the mapping.
• Each of these variables is checked separately to determine whether it is to be set or not.
• In case a variable is set, it is used to determine character substitution and hence mapping.

Flow

• The variables are used if they are set explicitly.
• Otherwise, the first time you netlist, all the variables are populated with their default values. The second time onwards the variable values will be used. If you need to modify just a part of the character substitution list, you can do it by modifying the variable in the CIW window. Otherwise the default values are used throughout.
