Can a cell-level CDF stay with its cell, regardless of library?

caver456

In order to add control to pcell parameters in the edit parameters GUI (i.e. make a cyclic field, change the parameter display text, etc) I understand you need to use CDF.  (Interesting that this support case uses the wording that CDF is "the best method"... that implies there's another way... is that true?) - CDF works nicely, but, it looks like a base-cell-level CDF still depends on the library it was created with, i.e. if you copy that cell to a different library that doesn't have the same CDF, then the pcell edit parameters form will use the default display (i.e. actual pcell parameter names as the field labels; no cyclic fields; etc).  One post mentions that you can copy the CDF of the cell along with the cell itself by using ccpCopy but that seems pretty cumbersome and I didn't get it to work as expected.

The CDF docs seemed to indicate you could attach a CDF to a cell only, but maybe I'm misunderstanding?  Based on all of the above, it looks like a cell-only CDF is only valid for that cell when it is in the library specified in the cdfCreateBaseCellCDF command?

In other words, is there a way to get a nice clean modular independent pcell along with the user-friendly edit parameters form fields, such that the cell can be copied to any library and still work and look the same?

  • Thanks, that looked like the ticket, I was not aware of that form. However, still no luck, so there must be something I'm not understanding:

    Basically, as the acid test to see if the copy worked after each attempt as below, I did CIW -> Tools -> CDF -> Edit, scope=cell, layer=base (also tried effective and since I don't have any user cdf it is unchanged vs base); selected the source library and cell to make sure it looks as expected (each parameter has a row with prompt and all the relevant columns filled out) and then selected the target library and cell, and in each case there are no populated rows. Also tried the actual pcell placement of the copy target to reconfirm, and in each case it did not have the cdf-style fields.

    Looking at the doc description of copy preferences form, it's not too helpful - when I opened up that form, 'do not add dependent property files to copy sets' was selected (otherwise it's the same as the image you sent), so, I figured that was the problem. So I changed it to 'Automatically add...' and unchecked 'Libraries' to avoid the library's data.dm conflict warning, since I don't want to copy that anyway. Deleted the existing cell in the target location (i.e. the previous attempt), then did the copy again, and, no luck as above. Thinking something was just stuck in the cache, I deleted the target cell, restarted Virtuoso, selected 'Automatically add...', did the copy, no luck. Also tried the above with 'include every file inside each cellview'; no luck.
