vpalias

Display or change a viewpoint alias

Syntax

[[px]] vpalias [=expr]

Where:

[px]

is a viewpoint override, including punctuation ( [ ] ), specifying that the viewpoint is temporarily set to processor x of the boundary scan chain.  The processor can be specified as px (where x is the processor ID), or an alias you have defined for a given processor ID.  ALL cannot be used as a viewpoint override.

expr

is a string or an expression that evaluates to a valid string.

Discussion

Use the vpalias command to define an alias for a processor. Specifying an empty string clears an alias.

The first character of an alias name must be a letter.  Subsequent characters can be letters or numbers.  Alias names are case-insensitive.  Alias names are limited to 6 characters.

Aliases can also be viewed and changed in Options | Target Configuration | Devices.
