ABS Caching Level
There are three levels of ABS caching available: None, Stop/Restart, and Multi-Sweep plus Stop/Restart. The options for ABS caching level are found in the Configure ABS tab in the Advanced Options in the EM Options page in the Circuit Settings dialog box in the project editor. To access these options, select Circuit ⇒ Settings, then click on "EM Options" in the sidebar menu of the Circuit Settings dialog box which appears. If the Advanced Options are not displayed click on the > Advanced Options button, then select the Configure ABS tab. The default is Multi-Sweep plus Stop/Restart.
Stop/Restart retains the cache data while the analysis is proceeding. Once the adaptive data has been calculated, the cache data is deleted from the project. This setting provides for the circumstance in which the analysis is stopped or interrupted before the adaptive data is synthesized; you will not lose the internal data produced so far.
Multi-Sweep with Stop/Restart retains all calculated cache data in your project for every analysis job run. In addition, cache data is calculated and saved for even non-ABS types of sweeps. This option can reduce processing time on subsequent ABS analyses of your project but increases project size on non-ABS sweeps. In order for the cache data to remain useful there are also subsectioning issues of which you must be aware. For a detailed discussion of the Multi-Sweep cache option, please refer to Multiple ABS Sweeps and Subsectioning.
The third setting for ABS caching level is None. In this setting cache data is not retained. This option should only be selected if you have constraints on disk space.
If you select None for the ABS caching level, and an ABS sweep is stopped before the adaptive data has been calculated, you will have to start the analysis over from the beginning. Any processing time invested in the analysis is lost.
