Cellview History
Virtuoso Studio Design Environment maintains the history of cellviews you access. Using this history, the environment displays a list of cellviews you access in the CIW File menu. You can open a recently accessed cellview directly from the File menu.
Virtuoso Studio Design Environment does not consider the application tier that was used to open the cellview previously. For example, open a cellview in Layout EXL and close it. The CIW File menu should now include an entry to access this cellview. Open the cellview from the CIW File menu. The cellview opens in Layout XL and not Layout EXL.
Filtering Unavailable Tiers when Opening a Cellview
When a cellview is saved in Virtuoso, information about its contents is saved in the property bag, which is the data.dm file. When the cellview is reopened from the Open File form, information in the property bag is read to determine the application tiers that support the data contained in the cellview. Based on this information, only supported tiers are displayed in the Open File form.
For example, consider that you have a layout cellview and you create a virtual hierarchy in it. You need Layout EXL to open this cellview because it is not supported in Layout XL. The information that cellview uses virtual hierarchy is saved in its data.dm file. Next time when you open this cellview, only Layout Viewer and Layout EXL gets displayed as the available choices to open the cellview and Layout XL is not available.
