Every Semiconductor Design Discipline, In One Team
DNCL Technologies covers the complete VLSI flow — front-end RTL design and design verification, DFT insertion, backend physical design and physical verification, static timing analysis signoff and FPGA prototyping — so your chip never has to change hands between vendors.
Physical Design Services — RTL to GDSII
Backend VLSI physical design engineering that converts a synthesised netlist into manufacturable, timing-clean, tapeout-ready layout. Our PD engineers own the flow from floorplan through signoff on nodes from 180nm down to 5nm FinFET, closing timing, power, IR drop and congestion together rather than trading one against another.
- Floorplanning & power planning — macro placement, partitioning, power grid and pad ring design
- Placement & CTS — congestion-driven placement, clock tree synthesis, useful skew and clock mesh
- Routing — detailed routing, signal integrity, crosstalk fixing and double-patterning aware routing
- Timing closure — MCMM STA, setup/hold fixing, SDC constraint development and physical-aware ECO
- Low power — UPF/CPF flows, multi-Vt swapping, clock gating, power gating and MSMV domains
- Reliability signoff — IR drop, electromigration, thermal analysis and GDSII stream-out
Physical Verification & Tapeout Signoff
Physical verification is where a tapeout is won or lost. Our PV engineers run foundry-qualified signoff decks to prove your layout is manufacturable, electrically correct and matches the schematic exactly — then close every violation with the designer rather than handing back a report.
- DRC — design rule checking and DRC+ closure against foundry runsets
- LVS — layout-versus-schematic, connectivity, short and open debug to clean netlist match
- ERC & antenna — electrical rule checks, antenna ratio fixing and diode insertion
- ESD & latch-up — PERC-based reliability verification and guard structure review
- DFM — density checks, metal fill, litho hotspot review and yield-oriented cleanup
- Signoff — parasitic extraction (PEX), post-layout STA, LEC against RTL, GDSII/OASIS stream-out
Full-Custom Analog & Mixed-Signal Layout
Analog layout decides whether a carefully designed circuit actually meets its specification in silicon. Our layout engineers work directly alongside your circuit designers on matching, isolation and parasitics — delivering layout that silicon-correlates with simulation the first time.
- Block coverage — PLL, ADC, DAC, LDO, bandgap reference, op-amp, comparator and SerDes
- Mixed-signal & power — PMIC, RF front-end, high-voltage and I/O ring layout
- Matching — common-centroid, interdigitated devices, dummy structures and symmetry
- Isolation — guard rings, deep n-well, substrate coupling and noise-aware floorplanning
- Parasitic-aware layout — RC minimisation, shielding, EM/IR-robust power routing
- Verification — post-layout simulation, LVS/PEX correlation, ESD and latch-up safe practices
