Resolving Check Errors

When a check command results in errors or warnings, the editor displays a flashing highlighted marker on each object that generated an error or warning.

If your design has errors or warnings, the Check – Find Marker command lets you view them easily by listing the corresponding error and warning messages in the Find Marker form.

■Floating input

■Floating output

■Floating net

■Floating switch

■Floating I/O

■Shorted output pin
