lxRemoveDevice Property

Description

The property is automatically converted to the new Layout XL schema underlying the physical hierarchy configuration.

To cause parasitic devices to be merged:

1. From the layout window menu bar, choose Launch – Configure Physical Hierarchy.
2. In the Instances table, select the logical instance in which you want to merge nets.
3. In the Generation tab, type the argument into the Remove device text field.

lxRemoveDevice is recognized by Layout XL if the shell environment variable, "CPH_USE_SCHEM_PROP", is set to 1 and the property has not already been set in the physical hierarchy configuration.

lxRemoveDevice can be set in the physConfig due to a previous automatic conversion or by directly editing the physConfig.

You can use the Add ignore command from the shortcut menu of an instance or pin to add the lxRemoveDevice property. For an instance (or pin) that already has the property added, the shortcut menu provides a corresponding option to remove the property.

The shell environment variable below must be set before launching the Virtuoso session.

setShellEnvVar("CPH_USE_SCHEM_PROP=1") or setenv CPH_USE_SCHEM_PROP 1
