Environment Variables
This appendix describes, in alphabetical order, the schematic environment variables that control the characteristics of the schematic editor and the behavior of many schematic editor commands. You can customize the behavior of the schematic editor by changing the value of a particular environment variable.
The Navigator Environmental Variables define the behavior of navigator commands. These are listed at the end of this appendix.
For information on layout and graphic environment variables, that control how various layout editor and window display commands work respectively, see
Changing the Default Environment Variables
To change a default variable or setting,
-
From the view, choose Options – Display, Options – Editor, or Check – Options.
For more information, see Virtuoso Design Environment User Guide.
Copying Environment Variables from the Samples Directory to ~/.cdsenv
To change environment variables in the .cdsenv file,
-
Copy the variables you want to change from the default
.cdsenvfile to the.cdsenvfile in your home directory.
The default file is located atyour_install_dir/tools/dfII/samples/.cdsenv -
Edit the default values in your home directory.
The.cdsenvfile in your home directory is loaded last; any values in your home directory override those previously loaded.
Checking the Value of an Environment Variable
To determine the current value of an environment variable,
-
In the CIW, type
The default setting for the environment variableenvGetVal("view" "envVar")browserTypeislibrary.
Setting Environment Variables in the CIW
To set the environment variable in the CIW,
-
Type the following SKILL function:
envSetVal(
For example:"editorName""env_var_name"type_of_valuevalue)envSetVal(
Using this procedure, you specify the specific environment variable as an argument for the"schematic" "browserType" ’string "component")schGetEnvandschSetEnvSKILL procedural interface functions.
For information on envGetVal and envSetVal, refer to Cadence User Interface SKILL Reference.
Changing Graphic Environment Variables That Are Cellview Properties
Some graphic environment variables are cellview properties. To make the changes to the environment variable visible in the cellview window immediately,
-
In the CIW, type
window = hiGetCurrentWindow() window~>
For example:environmentVariable=valuewindow = hiGetCurrentWindow() window~>autoDot = t
This changes the environment variable for the current window only, and you must reset the variable if you open a new window. The change is effective for the current session only.
Retaining the Current Settings for Future Sessions
To retain the current settings for future sessions,
-
From the view, choose Options – Save Defaults.
The system writes to the.cdsenvfile automatically whenever you choose Options – Save Defaults. If the file already exists, the system prompts you to overwrite the file or save it using another name. For details, see Saving Form Field Default Settings.

aelEvalCDFParam
schematic aelEvalCDFParam boolean { t | nil }
Description
Displays the evaluated results of the AEL expressions for CDF properties in the Property Editor assistant. The default is t. The CDF properties of an instance could contain expressions for its parameter values. These expressions use AEL and can include mathematical operations and functions that reference other property values. When the environment variable is set to t, it displays the evaluated result of these AEL expressions. Only the CDF properties that have parseAsCEL and parseAsNumber enabled are evaluated. Set the CDS_Netlisting_Mode SHELL variable to Analog to ensure that the AEL evaluator is able to find the CDF property in OA. See also Effect of Netlisting Mode On Labels.

descendDemoteViewNameList
schematic descendDemoteViewNameList string { "view_to_be_filtered" }
Description
Specifies a space-separated list of view names that appear at the end of the descend choices. Definition of this environment variable prevents you from descending into a view that is not useful for editing or interaction. This environment variable affects only the VSE Descend command. For example, in the parasitic flow, the estimated view is bound by the configuration. Therefore, it appears as the first choice in the viewNameList when descending into a view. However, you can define this environment variable as follows to place the estimated view at the end of the descend choices:
envSetVal("schematic" "descendDemoteViewNameList" 'string "estimated")
The default behavior of the Descend command is that the descend view choices are available in a sequence as specified by the configuration or the viewNameList, followed by any other views of the cell in an alphabetical order. Therefore, the default value for this environment variable is "" (an empty string), which means there is no change to the default behavior of the Descend command.

Descending Using the Descend Command
differential
schematic differential boolean { t | nil }
Description
Used by the schHiCreatePin() command. When when set to t will add a Differential Expansion field to the Create Pin form. The default is nil.
The differential variable is used to allow you to use the Virtuoso Schematic Editor for differential circuit design.
Firstly, set the global variable differential to t. This can be done by calling schSetEnv("differential" t) in your .cdsinit file.
Secondly, modify the differential name expansion algorithm as necessary and load from your .cdsinit file.
The current differential name expansion algorithm has the following feature:
- Simple, vector and bundle names can be expanded.
-
A simple name is always expanded by creating a vector of 2 bits wide.
For example,Aexpands toA<0:1>, B<2>expands toB<4:5> -
A vector name is always expanded by calculating the proper starting index and then doubling the width of the given vector.
For example,NAME<2:5>expands toNAME<4:11>,NAME<3>expands toNAME<6:7>
The starting part is calculated bys = v1*2
The ending part is calculated bye = v2*2+1 -
A bundle name is handled by breaking the bundle name into simple or vector names and applies the above rules.
For example,A,Bexpands toA<0:1>,B<0:1>,D<1,3>expands toD<2:3>,D<6:7>
