As the demand for advanced electronics and intelligent systems grows, Very-Large-Scale Integration (VLSI) design has become the backbone of modern semiconductor innovation. Whether you’re a fabless startup, OEM, or product company, finding the right VLSI design services partner can make or break your next chip.

In this guide, we explain what VLSI design services include, why companies outsource, and how to evaluate the best partner for your need

What Are VLSI Design Services?

VLSI design services refer to the outsourcing of specialized chip design tasks—from front-end RTL development to back-end physical design and verification. These services help companies reduce development time, cut costs, and access top-tier engineering expertise without building large internal teams.

At Nsemi Design, we offer end-to-end VLSI design services, helping clients from RTL to GDSII and beyond.

Core Components of VLSI Design Services

Here’s what most companies offer under the VLSI service umbrella:

1. RTL Design & Microarchitecture

• Writing synthesizable code (Verilog/VHDL)
• Architecture definition, IP block integration
• Protocol-based design (AXI, PCIe, USB, etc.)

2. Functional Verification

• UVM/SystemVerilog testbenches
• Simulation, assertion-based, and formal verification
• Bug traceability and coverage reports

3. Design for Test (DFT)

• Scan insertion, boundary scan, ATPG
• Built-In Self Test (BIST) and coverage analysis

4. Synthesis and Timing Closure

• RTL to gate-level synthesis
• Constraint management and optimization

5. Physical Design

• Floorplanning, placement, clock tree synthesis, routing
• STA, IR drop, EM analysis, LVS/DRC closure

6. Signoff and Tape-Out Support

• Final timing signoff
• Foundry-ready deliverables

Why Companies Choose VLSI Design Services

Outsourcing VLSI design allows businesses to:

• Reduce cost & time-to-market
• Access niche skills (like low-power design or AMS verification)
• Scale quickly with minimal overhead
• Focus on core competencies like marketing or system-level design

How to Choose the Right VLSI Design Partner

Not all service providers offer the same quality or flexibility. Here’s a quick checklist:

✅ Technical Competence

• Experience with advanced nodes (e.g., 7nm, 16nm)
• Familiarity with industry tools (Cadence, Synopsys, Mentor)

✅ Track Record

• Past tape-outs and commercial silicon successes
• Testimonials or case studies

✅ Flexible Engagement Models

• Project-based, hourly, or dedicated teams
• Onsite, remote, or hybrid delivery

✅ Strong IP and Documentation Practice

• Secure code sharing
• Version control and traceability

✅ Training and Staffing Support

• Some companies, like Nsemi, offer trained engineers via VLSI career programs
