DVM - Design Verification Module

Alias()

The Alias() function allows you to create a duplicate scalar for measurements that are automatically generated after a DVM simulation test. For example, the following scalars are automatically generated for each Bode plot test objective:

gain_margin
phase_margin
gain_crossover_frequency

Comparing the gain_margin in one test with the gain_margin in another test with different operating conditions is difficult since both measurements have the same name. Using the Alias() function to rename the scalar to reflect unique operating conditions can help with this comparison.

Alias() Syntax

The Alias() function has the following syntax with the arguments described in the table below:
Alias(scalar_name, new_scalar_name)

Argument	Description
scalar_name	Default name for the scalar.
new_scalar_name	Name as you want it to appear in the report.

Note: The value of new_scalar_name is identical to the value of scalar_name. If the scalar you attempt to rename is not generated for this test, the Alias() testplan entry is ignored.

IMPORTANT! Scalar names with spaces will produce errors when used with the Alias() function. The best solution is to create unique scalar names without spaces.

For more information on the Alias() function, see 6.4.1 Creating Scalar Aliases in the DVM tutorial.
