Parameter libraries are free parameter files that can be shared by several timing diagram projects. They contain the timing parameter information of components. The timing diagram editor ships with several standard libraries that contain over 10,000 timing parameters, and it also supports the industry standard TDML on-line component information (see T11.13 TDML Support). You can also use the timing diagram editor to create your own libraries.

Diagrams can also be merged into one another so that waveforms and parameters are visible in one diagram. When merging diagrams parameter conflicts are displayed in a dialog and can be resolved before the merge begins.
