Design Tapeout Submission Process by Participating Institutions (PIs)

Step 1: Obtaining Silicon Number by PIs

1. The PIs to send an e-mail to ChipIN Centre to get the Silicon Number with duly filled Silicon_Number_Generation_Form (see attachment) by 24th March 2026. Please go through the Silicon_Numbering_Table (see attachment) for various code details to be used for filling it.
2. ChipIN Centre to provide Silicon number to the PI.

Step 2: Submission of Design

1. Participating Institutions (PIs) to provide their design details in the Design Tapeout Submission Form (DTSF) and Process Information Sheet (PIS sheet) for projects intended for tapeout at 180nm, SCL Mohali.
2. The DTSF provides information on various items, which must be considered when a design is submitted by PI to ChipIN Centre.
3. All the columns in the PIS sheet must be filled with the drop-in information, wherever provided. At places, where drop-in is not given, designer must write as per the column description only.

General Guidelines

1.0 Data Format and Communication:

1. Acceptable database format is GDSII only.
2. Complete database must be sent through e-mail to chipin@cdac.in. Do not provide any Google Drive link.
3. The communication has to be addressed through e-mail at:
   • To: chipin@cdac.in
   • CC: venkatark@cdac.in, viviand@cdac.in, support.c2s@meity.gov.in
   ChipIN Centre,
   C2S Programme,
   C-DAC Bangalore, Opp. HAL Aeroengine Division,
   Old Madras Road, Byappanahalli,
   Bengaluru - 560 038.

2.0 Layout Grid

1. Minimum grid size used in the GDSII must be integer multiple of 0.005 µm.
2. Final GDSII window (including seal ring) must have Bottom left corner at (0,0) coordinate and the Top-Right corner coordinate must be rounded off to closest even number and it should be without any decimal places i.e., 10102 µm or 10100 µm for the case if coordinate comes at 10101.395 µm.

3.0 Design Kit

1. Do not rename cell names used in cell library.
2. Do not use library cell name for custom designed cells.
3. Do not edit standard cell library and I/O library.

4.0 Design Verification

1. The PIs to provide a clean GDSII database w.r.t. DRC, Density, and Antenna rules.
2. Before taping out the data, please provide checksum for GDSII file. Save the checksum value and byte count in a file, so that the same can be crosschecked at our end. e.g. cksum C2S0001_01062025_v1.gds 12345678 204 C2S0001_01062025_v1.gds
3. For GDSII integrity check while data transfer, MD5 checksum is must and need to be provided in addition to checksum so that the same can be crosschecked at our end. For calculating MD5, just open Linux terminal and type: md5sum ‘filename’ e.g. md5sum C2S0001_01062025_v1.gds
4. GDSII name and Top cell name format:
   • Format: silicon_no_date_version.gds (date format should be ddmmyyyy)
   • Top cell name should be "silicon number" only.
5. All the reports should be named as GDSII name. For instance:
   • siliconnum_date_version_drc.rpt
   • siliconnum_date_version_drc.summary
   • siliconnum_date_version_ant.rpt
6. All the columns in the Process Information Sheet (PIS sheet) must be filled with the drop-in information wherever provided. At places where drop-in is not given, designer must write as per the column description only.
