checkBeepOn
Specifies whether the system beeps after every save and check-in. If set tot, the system beeps even if there is no error or warning message. The benefit of turning this option on is to let you know when the check is complete. If set to nil, the system restores the behavior to release 4.3.x (the system beeps only when an error or warning is found). Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”

checkHierSave
Specifies whether the system saves schematics as they are processed during a hierarchical check. When nil, schematics are not saved during processing, which allows you to save or discard the edits manually. When t, schematics containing zero errors are automatically saved. For those schematics that do contain errors, whether they are saved is based on the value of the saveAction variable.

checkSymTime
Specifies whether the system runs a consistency check of the symbol masters and specifies the level of the check. When you specify a level of 0, the system does not run a consistency check. When you specify a level of 1 to 3, the system attempts to run the specified check during loading. A level 2 check attempts to run the level 1 check first. A level 3 check attempts to run both the level 1 and level 2 checks first.
When you set the value of this variable to 1, the system generates a warning when the value of a symbol’s instancesLastChanged property is newer than the schematic’s instancesLastChanged property.
When you set the value of this variable to 2, the system generates a warning when the value of the symbol’s UNIX file modification time stamp is newer than the schematic’s. The system does not run this check if the level 1 check fails.
When you set the value of this variable to 3, the system generates a warning when the value of the symbol’s check-in time stamp is newer than the value of the schematic’s instancesLastChanged property. The system does not run this check if either the level 1 or level 2 check fails.
