The DRC problem of local density violation near inductor for TSMC process

We have drawn some inductors using TSMC90nm as alternatives for the inductors supplied by PDK. But after we run DRC there were some problems of local density violation near the inductor(there were only bottom-most metal M1 and Top-most metal M9 in the checking window, so the density of other layers of metal are too low). Could anyone suggest some solution? Thanks a lot.:shock:

Sometimes it is necessary to use switches to get error free DRC; few years back I also got similar problem while designing a circuit in UMC 180 nm technology.......then I used switches to get rid of it.....the DRC was cleared and post layout was fine too and the fabricated circuit worked nicely.....

U can contact some TSMC personnel too through Europractice......

Thank you very much!:!:

Could you explain a bit more about where these switches are? Is there any information about the usage of these switches in the documents supplied by TSMC?
