| File: S130padPcell.il |
| Purpose: Pcell code for layout and/or symbols, and cdf setup for the pads |
| for Skywater S130 Pcell |
| |
| Created: June 21, 2020 Madek Graham |
| Description: Pcell code to create pad devices |
| |
| Devices/views: pad_bond / symbol auCdl auLvs layout |
| pad_probe / symbol auCdl auLvs layout |
| pad_microprobe / symbol auCdl auLvs layout |
| |
| ------------------------------------------------------------ |
| Modifications: |
| - Nov 2, 2020 MSG |
| Added marker layers for I/O, Power, or Ground pad type, as well as new CDF |
| parameter to flag the pad type. |
