  • Saving signals inside schematic pcell?

    Hi all, I have a schematic pcell that represents an array of devices, parametrised by the number of devices in the array.

  • question about using dbCreateParamInst

    I am writing a pcell using dbOpenCellViewByType and dbCreateParamInst When I tried to change parameters, it returned error "dbCreateparamInst: cellView is opened read-only." When using the default values it works fine. What's the problem of this? Thank you.

  • Parameters and pcells in ADE XL

    Hi all, I have a schematic pcell that generates an n-stage chain of (non-pcell) instances, each with different instance parameters. To do this, I have a pcell string parameter 'numStages' (also defined in the CDF for the cell), and something in the pcDefinePCell let block like n = atoi( numStages...

  • Can we fill a rodCreatePath with rectangles?

    Hi, There is an option to fill a rectangle with many small rectangles using subRectArray or rodfillbBoxwithRects. But is there a way to fill a path, created using rodCreatePath, with rectangles? I am writing a pcell code and need to fill a path with contacts. Thanks in advance.

  • Re: Slotted Metal paths

    Hi Lawrence, thanks for your reply and thank you for the script. I agree about the age of the code. I was hoping there might have been some update to it based on its age and the ubiquitousness of the application. I would like to enhance the form input to accept user defined bus widths without limitation...

  • pcell parameter order

    I used the GUI based method to create a pcell. When I use it in my layout, the parameters seem to be in random order. Is there an easy way to arrange them in a specific order e.g. alphabetically?

I have inherited a parameter 'width' among others from the pdk pcell to my custom pcell. In my custom pcell, I need to repeat contacts based on the value of...
