Display name of a cell child on schematic

Hi,

I have a design with generic cells with identical symbols. These cells contain different devices but always a single one (blackbox).

I would to know if it was possible to display the name of the device inside my cells. Something like an Interpreted Labels. The point being to do this automatically as soon as the child is modified. So ideally having a callback with a skill script modifying what my top cell is displaying.

Thanks in advance,

Not sure how good it will work for you, but you could create a property to the instance and have a textDisplay dislay the value.

Kinda like how fets values are displayed.

If the instance changes, either you will have to implement the update manually or create a trigger to update the value.

Hi,

Thank you for your answer. I managed to solve my problem using triggers. I created a trigger on every schematic opening that updates a Label on my top cells. The label is chosen by the name of the instances inside the top cell.

That doesn't sound a great solution, because it would need write access to the cellView plus it means you'd need to check and save the design each time before netlisting.

I think you could adapt the idea within this code: https://community.cadence.com/cadence_technology_forums/f/38/p/31041/1339207#1339207 . That would allow you to find the switch view that has been picked by the config; if no config was in use, you would probably revert to searching via a switch list list. Then that code could open the underlying view that was selected, look for the instances in question, determine the info you want, and then return a formatted string to show the info.

Regards,

Andrew.
