A PDK is the foundational library of design rules and device models that maps a chip design onto a specific fabrication process. Reliance on foreign PDKs (TSMC, GlobalFoundries ecosystems) locks Indian designers to overseas fabs and licences, making an indigenous PDK central to the India Semiconductor Mission's goal of an end-to-end domestic chip pipeline [1].

Significance of an indigenous PDK - Strategic autonomy: enables a full design-to-fabrication cycle at home, not merely design exposure, in a dual-use technology [1]. - Lower entry barriers: free, Aadhaar-authenticated access via eChipHub aids students, startups and MSMEs building a fabless talent pool [1]. - Ecosystem seeding: SCL's shared wafer runs already yielded 122 chip designs from 46 institutions and 75+ patent filings, proving academia–fab linkage [1]. - Caveat: the 1.2 µm node is a mature/legacy node, apt for teaching and analog/ASIC prototyping, not leading-edge computing—so it complements, not replaces, advanced nodes.

Role of NIELIT and SCL - NIELIT (MeitY autonomous body, Ropar) implements eChipHub and targets training ~30,000 students via bootcamps and internships [1]. - SCL Mohali (MeitY fab) provides real silicon; a ₹4,500 crore modernisation (announced Nov 2025) targets a ~100x wafer-capacity rise, ruling out privatisation [2]. - Their MoU (Apr 2025) models skilling–fabrication convergence between public and autonomous bodies [1].

Such institutional synergy operationalises Atmanirbhar Bharat in electronics; scaling toward advanced nodes and sustained EDA-tool access will convert this design capability into genuine self-reliance.
