pcell instance

  • Cell name as a pcell variable

    Hi, I have developed a skill based pcell for a particluar device. One of the parameters for the pcell is a string which is the name of a cell in the library I am working. It works fine, but when I try copy these pcells into a diferent library I do not see these cells copied since cadence thinks they...

  • symbol PCELL extraction issue.

    I have created a symbol, schematic and layout pcell. Everything seemed to be working correctly until I wanted to start LVS-ing the the pcell. I first ran into an issue where it required that my schematic be extracted since last edit. So I followed the instructions here: ___Schematic PCell: Schematic...

  • 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...

  • 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...

  • Optimal (fast) callback for pcells

    What is the optimal (fast) callback procedure for pcells? For example, I have a pcell that draws a shape that has a resistance. The value of the resistance is calculated inside pcell. I need to know the resistance of the instance, for example, to create another resistorwith a predefined total resistance...

  • Update P-Cell calculations

    Hi, I'm trying to write a skill script to update pcell parameters for a schematic, and then run a simulation. With help of forums so far, I've been able to get to updating the parameter width parameter: cv = dbOpenCellViewByType("afe" "amplifer2" "schematic" ""...
