lxParamsToIgnore Property

lxParamsToIgnore string list_of parameter_names

Description

Specifies the device parameters to be ignored when using the following Layout XL commands.

• Generate All From Source
• Generated Selected From Source
• Generate Clones
• Check Against Source
• Update Components And Nets
• Update Layout Parameters
  
  Cadence recommends that you use lxParamsToIgnore instead of the lxIgnoredParams property.

The lxParamsToIgnore property can be set on an instance in the schematic or layout or on the instance master.

If the property is set in the schematic, the shell environment variable "CPH_USE_SCHEM_PROP" must be set to 1.

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

Additional Information

You can also specify the parameters to be ignored by the Generate, Update, and Check commands in the Configure Physical Hierarchy window. To do this,

1. From the layout window menu bar, choose Launch – Configure Physical Hierarchy.
2. In the Instances table, select the schematic instance for which you want to ignore parameters.
3. In the Parameters tab, list the parameters to be ignored in the Ignore for generation text field.
   This overrides the global setting on the Parameters form.
