Create a sample mesh

If you have not created the "2by2_unit" layout yet, please click here.

Now that we need to use "2by2_unit" to build a "test_mesh" layout. This would be our final metal mesh layout. 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. Start with a new layout cell view "test_mesh". Please refer to Layout Edit Help on how to create a new layout.
2. In layout window, click Instance icon, a Create Instance window will pop up:
   
   
   
   
3. Type in "2by2_unit" in cell input:
   
   
   
   Type in Mosiac parameters:
   Rows = 2
   DeltaY = 72
   Columns = 2
   DeltaX = 72
   Red circle indicates user input.
4. A warning window will pop up, just click on Close.
   
   
   
5. Place the "2by2_unit" mosiac at x=0.0, y=0.0; zoom out to see whole design. You just create a metal mesh!
   
   
   
6. If you need to change your mesh size:
   
   
7. You got a bigger mesh!
   
   
   
8. Just add anchor borders! How? By adding 4 rectangles.
   
   
9. Save your layout. Congratulations! You have just designed a mesh and learned how to use Pcell.

Pcell demo library available in hp_cds (for MOSIS HP 0.5 um process)
Includes:

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