snapEnabled

Specifies whether theAdd Wire command uses snap mode to complete a wire. For details, see Editor Options Form on page 780.

spanLib

Specifies whether the editor spans reference libraries when you use theCheck – Hierarchy command. You use the libList environment variable to specify the list of reference libraries.

srcConnByName

Specifies a check for naming conventions between wires and pins connected by name. This check verifies identical names that exist in more than one physically disjoint group of wires or pins. A user might have inadvertently connected objects when using a name that was already

used elsewhere in the schematic. Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”

srcFloatingBIDIR

Specifies the severity of the SRC signal check for floating bidirectional pins. Controls the check for component or schematic bidirectional pins whose signals are not driven by component output pins, schematic input pins, or any other schematic I/O pins. Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”

srcFloatingInput

Specifies the severity of the SRC signal check for floating inputs. Controls the check for component input pins and schematic output pins with signals that are not driven by component output pins, schematic input pins, or any schematic I/O pins. Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”

srcFloatingIO

Specifies the severity of the SRC signal check for floating I/Os. Controls the check for component or schematic input/output pins with signals that are not driven by component output pins, schematic input pins, or any other schematic I/O pins. Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”

srcFloatingNets

Specifies the severity of the SRC signal check for floating nets. Controls the check for wires that are not physically connected to schematic or component pins. It does not check for wires connected by name to schematic or instance pins. Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”

Environment Variables

srcFloatingOutput

Specifies the severity of the SRC signal check for floating outputs. Controls the check for component output pins and schematic input pins with signals that are not driving any component input pins, schematic output pins, or any schematic I/O pins.

srcInheritedConnCheck

Specifies the severity of the SRC inherited connections check. Controls the check for inherited connections.

srcInstNameExpr

Specifies the regular expression to use when the SRC instance name check is enabled. Specifies the regular expression used in the instance name check. Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”
