DVM - Design Verification Module

Graph Address System

The following curve functions require a graph address that specifies where to place the newly created curve on the graph..

Since the curve functions automatically create new graph tabs, grids, and axes, a testplan can have multiple functions that generate curves and the order of the testplan rows does not matter.

All of these curve functions require three arguments that define the graph address:

The graph_name argument specifies the name of the tab on which the curve appears.
The grid_index argument defines the order in which the curves appear on the graph. The value of grid_index is an alphanumeric string starting with the letter A, such as A1, A2, A3 etc. Analog grids are assigned grid indexes starting at A1,which is both the default and the bottom-most grid. The numeric indexes increase as additional grids are added to the graph.
The axis name argument specifies the name of an axis on the same grid index. Currently, this is used for only the default grid where the grid index is A1. Multiple axes can be added to the default grid index (A1), but the additional grids (A2, A3, etc) can have only a single axis. Currently, DVM supports up to 100 grids per graph tab.

Graphs created with these curve functions can also be placed on graphs generated from fixed probes or from other curve functions.

IMPORTANT! The graph address along with the curve name must specify a unique item on the graph - that is, a single curve. Errors result if you duplicate curve names on the same graph sheet or if you specify addresses that conflict. For example, if you already have an axis with a specified name on grid index A2, you will get an error if you specify a new axis with a different name on that same grid index A2.
