Getting variable names from schematic view

trdastidar

 Hi,

I am trying to integrate a third party tool into the Cadence environment, and have some questions on the APIs available for the task. I am not new to programming in general, but definitely new to SKILL. If someone can help me identify the SKILL APIs that can do the jobs that I mention next, it will be immensely helpful.

What I need are:

1. SKILL function to get all variable names from a cell view.
    Input: lib, cell, view name.
    Output: List of variables, and their values, if any.

2. SKILL function to set values to variables in a cell view.

Both of them are possible to do from Artist. Some of the Artist specific SKILL APIs can do this (sevCopyCellViewVariables and sevCopyVariablesToCellView.) However, they require the Artist window to be open. What I need is a function which can be invoked in the background, and can do the job without the corresponding Artist or Schematic window being open.

Thanks in advance

    Sorry, typo in my previous reply - it should have been artGetCellViewDesignVarList(). This is getting the variable names and values that have been saved back to the cellView with "Copy to cellView" (it actually copies them to the cell, rather than the cellView).

    The sevCopyCellViewVariables will traverse the hierarchy and add those variables into an ADE session. artGetCellViewDesignVarList does not do any hierarchy traversal - there's no public API (as I said) which will do that other than sevCopyCellViewVariables. Presumably when it collects them, they do not have any values - the only values will be found by virtue of the value having been stored in the designVarList property on the cell object previously.

    Regards,

    Andrew.
