Parameterized Cell Tutorial


    Parameterized Cells ( Pcell ) are a powerful tool to create Cadence layout designs. This Tutorial gives step by step instructions of how to create a Pcell for comb drive fingers and how to instantiate this finger Pcell to create a comb drive. Then, we will also use this Pcell to create a mesh for metal membrane designs. This tutorial assume you have set up and started Cadence properly. This tutorial is process independent. However if you choose to skip steps, pre-created tutorial Pcells exists in hp_cds (MOSIS HP 0.5um process).


    1. How to Create a "pcell_demo" Pcell

    Part I. Initialize Pcell environment
    Part II. Draw basic geometry
    Part III. Define parameters
    Part IV. Compile Pcell

    2. How to Instantiate "pcell_demo" Pcell

    Part I. Instantiate This Pcell
    Part II. Adjust Parameters

    3. Create a Mesh layout with "pcell_demo" Pcell

    Part I. Create "basic_unit" layout with "pcell_demo"
    Part II. Create "2by2_unit" layout with "basic_unit"
    Part III. Create "test_mesh" layout with "2by2_unit"


    All above Pcell/layout cells are available in demo library in hp_cds (for MOSIS HP 0.5 um process). For help with using hp_cds, click here.
    The demo library Includes:

    pcell_demo (fingers)
    basic_unit (fingers as a comb)
    2by2_unit (2 by 2 comb as minimal mesh)
    test_mesh (instantiation example)
