Schematic Check Options Form

The Schematic Check Options form sets up options to be run when you choose the following commands: Design – Check and Save, Check – Current Cellview, Check – Hierarchy,

Check – Cross View Check.

Connectivity Options

Update Connectivity specifies whether the system updates the connectivity of a cellview when you use the Check – Current Cellview command. When enabled (default), the system extracts connectivity from the design.

Beep When 0 Errors/Warnings when enabled (default), causes the system to beep after every save and check in even if there is no error or warning message. The benefit of turning on this option is to let you know when the check is complete. Disabling this option restores the behavior to release 4.3.x so that the system beeps only when an error or warning is found.

Check and Save Action on Error specifies whether the system saves schematics that contain errors.

Save saves all schematics including those that contain errors.

No Save saves all schematics except those that contain errors.

Ask Me (default) prompts you to confirm that you want to save a schematic that contains errors. When you choose this option and click OK, a dialog box appears. The dialog box lists all the schematics that contain errors and then prompts you to confirm which of the displayed schematics you want to save.

From a Multisheet Index, Check specifies which sheets in a multisheet schematic the system checks.

all checks all multisheets.

only if needed (default) checks only the multisheets that you have edited since the last check.

Wire Name Glue Distance specifies a distance, in user units, between wire names and their associated wires. During the check operation, the system looks for unglued wire names.

When the checker finds an unglued wire name within the specified distance from a wire, the system glues the wire name to the wire. When the unglued wire name is beyond the specified distance, the checker marks the unglued label.

Schematic Rules Check Options

Run Schematic Rules Check when enabled (default), specifies whether the system runs the schematic rule checks when you use the Check – Current Cellview command.

ignored results in no action. warning generates warnings. error generates error messages.

Views To Check displays a list of the views to be checked when you click OK on a Check command form.

Match Pin Names Exactly, when enabled, checks whether pin names match exactly when you click OK on a Check command form. For example, pins A<0> and A<1> in view1 and pin A<0:1> in view2 would not match.

Match Inherited Terminals, when enabled (default), checks whether inherited terminals match when you click OK on a Check command form.

Match Terminal Net Expressions, when enabled (default), checks whether terminal net expressions match when you click OK on a Check command form.
