Layout: Cannot change terminal from scalar to bus

The underlying reason is that the database cannot both a scalar and vector (bus) pin with the same base name, but in this case you're changing it so that shouldn't be a problem if the tool handled it properly. I did a quick search and found some reports of this, but all seemed to focus on giving a workaround (add a character, hit apply, and then replace the extra character with <0> and then apply again) rather than seeing if we could fix it properly. As a result, I didn't spot any change request to ask that the layout tool handle this behind the scenes.

So I would suggest you contact customer support and ask for a change request (CCR) to get Virtuoso Layout Suite to handle this.

Hi Andrew,

your workaround does not help. Now I have deleted everything except one pin. The layout is totally empty! And this pin has a completely different name. But if I try to rename this pin, the error still occur. There must be something strange in this database. Is there a way to look inside this database? Or can I manually update this database? Or something else?

Most likely there's either another pin on the terminal, or the terminal has been left behind (are you using VLS XL?). You can check by doing:

cv=geGetEditCellView()
term=dbFindTermByName(cv "THETERMNAME") ; where "THETERMNAME" is what you are looking for
term~>pins

If the last returns a list of db objects, there are still pins on that terminal that you might need to update to the intermediate name together. if not, you probably do dbDeleteObject(term) to remove it. Be careful in case you delete something you didn't meant to though!

My workaround was to rename to something else, thus freeing up the terminal name and allowing you to name it back to a vectored name. However, that only works if nothing is still using the original terminal name.

Yes, I am using XL.

I tried your commands:

but the error still occurs:

If I try the workaround by renaming the pin to
Vbb_1p6_PA_test
then this works. But if I try to rename this to
Vbb_1p6_PA<0>
then the error occurs. AND if I try to rename it to
Vbb_1p6_PA_test<0>
then the error occurs too!

Regardless which name I try, it is not possible to change a scalar pin to a bus pin. Even with the funiest name:

For completeness: If I try to create e new bus pin with the name which leads to the error, then I get this error:

Very strange!

I'd need to see the data to understand what is going on (I can't guess right now). Maybe it's because the net remains, but that seems unlikely given some of your experiments. You should contact customer support as I suggested earlier.

What data do you mean? The design itself? Maybe I can create a simple design which I can upload anywhere.

Ok, I will contact the support. I hopped I can get a solution here in the forum faster.

Thank you Andrew!

I mainly meant that an AE could look at your data together with you in (say) a webex session. The database would be great, but sometimes just being able to do some interactive exploration together can be helpful. 

Similarly I could put together an example which showed it working (the workaround, but not sure how useful that would be. I'd sooner use this as an opportunity to get across to R&D that this needs improving, hence the request to go via customer support.
