Opening Configurations in Hierarchy Editor

To open an existing configuration from the command-line when you start the Hierarchy Editor,

• In a terminal window, type
  

  cdsHierEditor -lib libname -cell cellname -view viewname

  You must specify all of the above options for the Hierarchy Editor to open a configuration and load the data. If you do not specify a cellview (that is, the library, cell, and view names), the Hierarchy Editor opens without loading a configuration.
  
  If the Hierarchy Editor cannot open the configuration for editing—for example, if the configuration does not have edit permissions or if it is already locked by another process—it brings up a dialog box that asks if you want to open the configuration in read-only mode. Click Yes to open the configuration in read-only mode.

To open a configuration from the Hierarchy Editor,

1. From the menu bar, choose File – Open or press Control-o.
   The Open form appears.
2. In the Library field, select or type the name of the library that contains the design.
   The drop-down list contains all the libraries that are defined in your library definition file (cds.lib) file.
3. In the Cell field, select or type the name of the cell that contains the configuration view.
   The drop-down list contains all the cells in the library you selected.
4. In the View field, select or type the name of the configuration view.
   The drop-down list only displays configuration views of the cell that you selected; it does not display any other views.
5. Click OK.
   The Hierarchy Editor opens the configuration.
   You can use the maskLayoutStopLimit variable in the hed.env file to specify a size limit for maskLayout cellview databases. If a configuration includes such databases that are larger than the specified size limit, they do not get opened and gets shown as leaves with display stop point icons. These display stop points do not affect netlisting or simulation.
   If the Hierarchy Editor cannot open the configuration for editing—for example, if the configuration does not have edit permissions or if it is already locked by another process—it brings up a dialog box that asks if you want to open the configuration in read-only mode. Click Yes to open the configuration in read-only mode.

To open a configuration in read-only mode from the Hierarchy Editor,

1. From the menu bar, choose File – Open (Read-Only).
   The Open (Read-Only) form appears.

   The drop-down list contains all the cells in the library you selected.
4. In the View field, select or type the name of the configuration view.
