A problem about using PDK in virtuoso

[melectronics]

Hi, all.

When I open my virtuoso library manager and click on the TSMC 90nm library, no cells appear in the cell column or the view column. This happened yesterday and never happened before. The possible reason is that too many people are accessing the PDK at the same time. But how to solve the problem? Thanks!

When I click on the TSMC 90nm library in the library column, the warning I get is as follows:

Warning: Couldn't get an exclusive lock for "/home/cadence/TSMCHOME/pdk/tsmcN90rf/TransmissionLine.Cat"
Permission denied
Warning: ddDeleteDeep: Couldn't get exclusive lock on ddLibFileType 'TransmissionLine.Cat'.
Warning: ddCatRemove: unable to remove category TransmissionLine.

Yes, some people have locked those files I guess, leaving it open and terminating session leaves these locks. One solution is to delete all .cdslck files associated with these, but this might cause problems with the other guys working on these. But since you are trying to remove those I assume you have the ownership of these files, therefore it shouldn't be that problematic.

Hi, the library files are open for read only. We as users do not have the authority to change the content in that folder. In my own folder, there is no lock file. Now, it is the technology library locked, not my own library. This is the most strange part.

Then you need to contact your administrator. Maybe he/she locked those files knowingly or not. But I don't know there's not much I can think of. I don't think I can help you any further, sorry about that.
