Modern electronics design sits at an uncomfortable intersection. Products have to shrink, run faster, draw more power, throw off more heat, and survive longer in harsher environments — all while the development cycle keeps getting shorter. DDSPLM helps electronics teams across India ship products that hold up in that environment.
What’s changing in electronics design
Power density is hitting walls that air cooling can’t solve
GPU thermal design power is climbing toward kilowatt class. Hyperscale data centres are moving to direct-to-chip liquid cooling as the default, with microfluidic and two-phase cooling on the experimental edge. The same pressure shows up outside data centres — EV inverters, fast-charging stations, and edge-AI boxes are bumping into the same wall. Air cooling is no longer the answer for a growing share of product categories.
Advanced packaging — 2.5D, 3D, chiplets — is now mainstream
Heterogeneous integration is the default for high-performance silicon. TSMC’s roadmap to System-on-Wafer integration with HBM stacks is the leading edge; chiplet-based products are already shipping today. The mechanical, thermal, and signal-integrity implications cascade outward to every board, enclosure, and cooling system those packages eventually land in.
GaN and SiC are reshaping power electronics
Wide-bandgap semiconductors enable higher switching frequencies, smaller magnetics, and denser power-stage layouts — but also produce worse EMI, harder high-frequency magnetics, and tightly concentrated thermal hot-spots. Validating a modern GaN/SiC inverter requires coupled electromagnetic + thermal + structural analysis, not three sequential studies.
Miniaturisation forces cross-discipline coupling
Thermal interface materials, PCB layout, enclosure geometry, and component placement interact more tightly when the device shrinks. The handoff workflow — mechanical designs the housing, electrical designs the board, thermal validates after the fact — produces too many late-stage surprises to survive a six-month time-to-market window.
AI is moving from buzzword to engineering tool inside CAE
The interesting AI development for electronics teams isn’t ChatGPT in documentation — it’s geometric deep-learning models like Altair physicsAI that train on past simulation data and predict structural, thermal or fluid outcomes orders of magnitude faster than a solver run. For dense PCB thermal trade-studies and power-stage geometry sweeps, this turns “we can run two variants overnight” into “we can run two hundred.”
Indian electronics manufacturing is scaling fast
The Production Linked Incentive (PLI) scheme has accelerated semiconductor, display, and electronics-manufacturing investment across India. New fabs and contract-manufacturing capacity are coming online, and the engineering teams behind them need the same tooling depth their global counterparts use — along with the quality-management discipline (APQP, PPAP, FMEA) that automotive-tier electronics customers demand.
What this means for engineering teams
Mechanical, electrical, thermal — and increasingly quality — disciplines have to share one model and one revision spine, not just hand off files. Thermal validation moves upstream into design. ECAD and MCAD round-trip cleanly. Power-stage products need coupled physics. Configure-to-order variants need PLM discipline so the BOM exception list doesn’t grow faster than headcount.
How DDSPLM helps
We deploy and support a calibrated toolchain:
- Siemens NX MCAD for enclosures, mounting and serviceability, with ECAD round-tripping to Siemens Capital.
- Simcenter Flotherm and FloEFD for electronics thermal simulation — package, board, and full-enclosure conjugate heat transfer.
- Simcenter MAGNET and Motorsolve for the EM side of GaN/SiC magnetics.
- Siemens Capital for the wire-harness and electrical-system layer beyond a single PCB.
- Altair physicsAI for AI-accelerated trade-studies on thermal and structural problems where a parameterised baseline already exists.
- Teamcenter PLM as the system of record for ECAD/MCAD revision pairs, change management, and BOM transformations.
- SFS SmartAPQP — our own APQP / PPAP / FMEA / Control-Plan platform, built for Indian electronics manufacturers serving IATF 16949 and similar customer-quality regimes.
- Cortona3D for service manuals and field-tech training generated from the same CAD models.
Engagement examples
- Thermal redesign of a densely-packed handheld product failing field tests in tropical climates. Rebuilt the thermal model in Flotherm, identified two component placements as the root cause, validated the fix before tooling.
- Power-stage redesign for a SiC traction inverter. Coupled EM, thermal, and structural simulation, with HEEDS driving an automated trade-study. Cut prototype iterations from four to two.
- Quality-system rollout for an Indian contract manufacturer onboarding a Tier-1 automotive customer. Deployed SmartAPQP for APQP/PPAP discipline alongside Teamcenter for ECAD/MCAD revision control.
