Environment Variables

srcInstOverlapValue

Specifies the overlap percentage to use when theSRC instance overlap check is enabled.

When enabled, the variable specifies the amount (as a percentage of the smaller instance bounding box) that two instances can overlap. Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”

Type

integer

Value(s)

n/a

Default

10%

Environment Variables

srcNoOverrideNet

Specifies the severity of the SRC check for missing override nets. Controls the check for override nets when a schematic contains override properties. If the override property is a net expression, the SRC will try to validate the property by ensuring the default name specifies a scalar, global name. If the override property is a literal string, the SRC will first validate the property by ensuring it is a legal, scalar name. In both cases, the SRC will then check if a net by that name exists in the cellview. Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”

srcOffsheetConnCheck

Specifies the severity of the SRC check for offsheet connectors. Controls the check for offsheet connectors used on only one sheet in a multisheet design. It also checks for nets used locally in more than one sheet that are not connected across the sheets by an offsheet connector. Setting schematic check options and rules are discussed in Chapter 10, “Checking Designs.”
