Modifying Tolerance and Bidirectional
Settings
You can allow the creation of iOLM bidirectional files for your analyses.
You can also set the extended element matching tolerance. The main
purpose to edit the tolerance is to match two elements that are not
matching with the intrinsic element tolerance value fixed by signal
processing.
To enable the iOLM bidirectional file creation:
1. On the Settings menu, click iOLM and then the iOLM Setting tab.
2. Enable the Display iOLM bidirectional file creation dialog option.
3. Click OK.
