  • Re: leLayerSize didn't work for pcell, is there any way around it?

    Hi Kathy, You cannot use le prefix functions in a PCell (or sch, ge etc. for that matter - check the documentation for a full list of what you can use). However, you have at least a couple of ways to achieve this functionality: use the dbLayerSize() function, or use the ?size and ?fromObj arguments to...

    Hi Sabyasachi, Your request is not clear at all, but it sounds like you might want to instantiate a PCell in another SKILL Pcell - if this is the case then there are two functions that you could use to do this: dbCreateParamInst and dbCreateParamInstByMasterName dbCreateParamInst( d_cellView d_master...

  • Re: automatic parametrised layout

    Hi Sabyasachi, In addition to what Quek has said, there are some sample SKILL PCell code examples in the installation hierarchy, and also a generic Process Design Kit ("gpdk") that you can look at and play with. Take a look in the following directories: <cds_install_dir>/tools/dfII/samples...

  • Re: How to instantiate a pcell in another pcell?

    Hi, The documentation is a good place to start for this, for example it contains this section: Creating Instances within Pcells It is often useful to create instances of other cells within a pcell. You can also create pcell instances within a pcell. For example, inside your pcell code, you can create...

  • Rotation for an arbitrary angle in Virtuoso

    I am designing a fancy transformer using Virtuoso Layout Editor. In fact, I would like to derive a corresponding code. It would be convenient for meto design a piece of the transformer and then copy it with a rotation. However, I noticedor did not find a skill function rotating on an arbitrary angle...

  • Open pCell for Edit Keeping pCell's Parameters

    When opening a pcell with dbOpenCellViewByType(), the pcell's parameters are set to the default values. If the pcell is instanced in another cell, you can open that pcell with cell~>instances~>master and the pcell's shapes will reflect any changes that were made on the pcell's parameter...

  • Re: ROD example

    By "transformer" are you talking about a layout which has overlapping or adjacent coils, such as those for an inductor? Could you use an inductor as a starting point for this? There is Solution 1809475 on SourceLink for a Spiral Inductor. Oh, while I was looking at that Solution, I noticed...
