Core Services
Every Phase of the Silicon Lifecycle
Modular engagement — bring us in at architecture, verification, physical design, or full flow. We integrate seamlessly with your existing team.
Architecture & Microarchitecture
Chip-level partitioning, pipeline design, clock/power domain planning, and performance modeling with cycle-accurate simulation.
RTL Design & Coding
Production-quality RTL in Verilog, VHDL, and SystemVerilog with strict coding guidelines for synthesis and lint-clean delivery.
Functional Verification
UVM environments, constrained-random testbenches, coverage closure, assertion-based verification (ABV) and formal property checking.
DFT — Design for Test
Scan insertion, ATPG pattern generation, JTAG boundary scan, memory BIST, and DFT sign-off for full production test coverage.
Physical Design (RTL2GDSII)
Floorplanning, placement, CTS, routing, STA, IR drop, EM analysis, and DRC/LVS-clean GDSII sign-off.
Pre & Post-Silicon Validation
Emulation-based validation using Veloce/Palladium, bring-up scripts, silicon debug, and performance characterization.
Our Process
How We Take Your Chip from Spec to Silicon
01
Discovery & Spec Review
Deep-dive into your functional spec, power targets, area budget, and schedule. We flag risks early and establish shared success criteria.
02
Architecture & Planning
Microarchitecture design, block partitioning, interface definitions, and cycle-accurate performance models validated against your requirements.
03
Design & Verification
RTL coding, UVM testbench development, regression runs, coverage closure, and formal verification — all with transparent weekly reporting.
04
Sign-off & Tape-out
Physical design completion, DRC/LVS clean, final STA, and full foundry-package GDSII delivery. Post-silicon bring-up support included.

FAQ
Semiconductor Design Services FAQ
Straight answers from the people who do the work — no marketing filler.
What are semiconductor design services?
Semiconductor design services cover the engineering work needed to take a chip from specification to production-ready silicon — architecture and microarchitecture planning, RTL design, functional verification, physical design (RTL-to-GDSII), design-for-test, and pre- and post-silicon validation. Companies use a design services partner like Silicon Patterns to access this expertise without staffing every discipline in-house.
What does your semiconductor design service actually cover, start to finish?
Everything from spec review through GDSII sign-off and post-silicon bring-up: architecture & microarchitecture, RTL design in Verilog, VHDL and SystemVerilog, UVM and formal verification, DFT (ATPG, scan insertion, MBIST), physical design (synthesis, place-and-route, STA, DRC/LVS), and pre- and post-silicon validation on Veloce/Palladium. You can bring us in for one phase or the full flow.
Which process nodes and EDA tools do you support?
180nm down to 5nm, including 22nm FD-SOI and 16/12nm FinFET. We're tool-agnostic — proficient in Synopsys, Cadence and Siemens EDA, plus open-source EDA stacks — so we work with whatever flow your foundry requires rather than forcing you into ours.
How long does a typical ASIC/SoC engagement take?
It depends on scope — a single verification phase runs on a different clock than a full spec-to-tapeout engagement. What's fixed on our end: we respond to project inquiries within 24 hours and return a detailed technical assessment, with a realistic schedule, within 48 hours of a discovery call.
Do you only work with large semiconductor companies, or startups too?
Both, on purpose. We work with fabless startups, growing technology companies, and established semiconductor enterprises — the engagement model flexes to fit, from a couple of augmented engineers up to full project ownership.
What engagement models are available?
Three: Full Project Ownership, where we run the flow end-to-end; a Dedicated Engineering Pod, a standing team embedded with yours; or Staff Augmentation, individual engineers slotted into your existing team. Most clients start with one and adjust as the project evolves.
How is Silicon Patterns different from other semiconductor design services companies?
Three things clients bring up most: one team covering architecture through GDSII, so there's no handoff risk between design and physical teams; a 98% first-pass silicon rate across 35+ client engagements; and being genuinely tool-agnostic instead of locked into a single EDA vendor's flow.
Do you support post-silicon bring-up, or just design and tape-out?
Design and tape-out is half the job. We also handle post-silicon validation — functional bring-up, characterization, and performance validation on real hardware once the chip is back from the foundry.
