Back-End IC Design
Netlist-to-GDSII physical implementation, signoff and tape-out coordination — built around PPA discipline and foundry-aligned methodology.

WHERE TIMING-CLEAN NETLISTS BECOME MANUFACTURABLE SILICON
Back-end IC design covers the physical implementation flow that turns a synthesized netlist into a GDSII layout the foundry can manufacture. The work includes floorplanning, power planning, place-and-route, clock tree synthesis, DFT insertion, and full signoff against timing, power, electromigration, IR drop, DRC, LVS and antenna rules before tape-out.
Our team executes physical design for digital and mixed-signal SoCs across mature and advanced nodes, working from customer-supplied netlists, libraries and constraints. Methodology adapts to the target foundry — we work with PDKs from TSMC, GlobalFoundries, SMIC, UMC, Samsung Foundry and Tower Semiconductor — and runs through the customer's preferred tool stack. Deliverables are foundry-ready: GDSII or OASIS layout, signoff reports, fill structures, ESD and latch-up review notes, and a documented tape-out checklist.
Key CAPABILITIES
OUR APPROACH
Foundry-Aligned Methodology
Foundry rule decks, PDK versions, signoff corners and design enablement kits drive the implementation flow — not the other way round. Our engineers work in the customer's chosen foundry kit from day one, follow that foundry's recommended STA derate methodology, EM/IR signoff criteria and DRC/LVS waiver convention, and document any deviation explicitly. When the customer plans a process shrink or a foundry change, the same discipline applies to migration: we replay signoff against the new kit rather than assume portability.
PPA Optimization Discipline
Performance, power and area are tracked as a trio from floorplan onward, not optimized one at a time at the end. Weekly PPA dashboards report frequency closure margin, leakage and dynamic power, area utilization and routing congestion against the targets in the contract. Trade-off decisions — useful skew versus power, density versus EM headroom, library Vt mix versus leakage — are surfaced with concrete numbers so the customer's architect can choose, rather than being made silently inside the flow.
Tape-Out Risk Management
A tape-out risk register is created at project kick-off and reviewed weekly with the customer. Items track foundry rule version dependencies, IP delivery milestones, signoff convergence status, ECO accumulation, mask order lead time and known issues with documented mitigation. Dry-run tape-outs are scheduled before the real one — full GDSII generation, signoff replay and foundry deck sweep — so the actual tape-out reveals no surprises. This is risk management, not heroics.
