The problem is not that standardized IP is bad. Standard IP has a clear and valuable role in semiconductor development. It is often pre-verified, broadly compliant, and efficient for teams that need a proven foundation quickly.

The limitation is that standardized IP is usually designed for the middle of the market. If a design sits at the edge of what is possible in performance, power, or area, the middle of the market may not be where the design needs to be.

In many advanced designs, even small inefficiencies in IP, such as extra logic, unused features, or suboptimal configurations, can directly affect performance, power consumption, and silicon cost.

As semiconductor designs grow more complex, the gap is widening between what standardized IP delivers and what cutting-edge chips actually need. AI accelerators, edge computing devices, smart vehicles, AIoT hardware, wearables, and high-performance SoCs all demand stronger performance, lower power, and smaller silicon footprints. Standard IP blocks, built for broad compatibility, often cannot optimize all three at once.

That is why customizable IP, often referred to as custom IP or configurable IP, is no longer a nice-to-have. SoC IP customization is becoming a core part of how leading semiconductor teams compete.

The Limits of One-Size-Fits-All Standard IP

Standard IP Has Value, But It Can Create Design Friction

Standardized IP has real value. It can reduce development effort, accelerate integration, and provide a protocol-compliant starting point. For many applications, it is exactly the right choice.

But for teams pushing the boundaries of performance and efficiency, generic IP can create friction. It may carry features a design does not need, impose constraints the architecture did not ask for, or leave PPA, meaning power, performance, and area, optimization on the table.

When a team is designing for a specific workload, interface, system architecture, or power envelope, that overhead can add up quickly.

Where Customization Matters Most

The need for customization is especially important in areas where performance, power, and area tradeoffs are most critical. These may include memory interfaces, on-chip interconnects, high-speed connectivity protocols, automotive systems, AI accelerators, and specialized embedded designs.

Customization enables design teams to:

• Eliminate unnecessary features to reduce silicon area
• Optimize performance for targeted workloads
• Modify protocol configurations to suit specific system architectures
• Improve power efficiency
• Align IP capabilities with distinct product requirements
• Support reuse across product families or future design variants

For advanced SoC teams, this can be the difference between adapting the design around available IP and using IP that is adapted to the design.

Customization Is Harder Than It Looks

Custom IP Requires More Than Parameter Changes

The appeal of custom IP is easy to understand: tailor the implementation, remove unnecessary features, and hit the design target more precisely. In practice, customization is more complex.

Effective customization often goes beyond simple parameter changes. It may require architectural modifications, protocol adjustments, interface changes, feature reductions, and full re-verification. Any meaningful change to the IP must be validated to ensure functionality, compliance, performance, and reliability are maintained.

Real-World Customization Scenarios

Common customization scenarios may include:

• Changing an SoC bus interface, such as adapting communication between different AMBA-based interfaces
• Adding internal DMA functionality that requires new hardware design and verification of data paths
• Supporting protocol extensions or project-specific implementation requirements
• Reducing gate count by stripping IP down to essential functionality
• Optimizing IP for a specific power, performance, or area profile
• Adapting IP for reuse across related SoC, ASIC, or FPGA programs

In safety-critical domains such as automotive, aerospace, medical, and industrial systems, functional safety expectations can add another layer of complexity.

Custom IP done well requires deep protocol expertise, a rigorous development process, and verification infrastructure that can validate each modification with confidence.

SmartDV’s Answer: IP Your Way

IP Should Fit the Design

Customization is not a side offering at SmartDV. It is central to how the company approaches semiconductor IP.

The idea behind IP Your Way is straightforward: customers should not have to adapt their designs to fit available IP. The IP should fit the design.

SmartDV brings together a broad portfolio of Design IP and Verification IP, along with deep engineering experience and a proprietary development platform called SmartCompiler™.

Customizable IP Built on a Proven Foundation

SmartDV’s approach allows teams to start from a proven, standards-based IP foundation and adapt it to meet specific project requirements. This helps reduce the tradeoff between speed and customization.

The result is customized IP that is designed to remain standards-compliant, production-ready, and aligned with each customer’s architecture, interface, verification, and product roadmap requirements.

SmartCompiler: The Engine Behind the Customization

Automating IP Development and Configuration

SmartCompiler™ supports the lifecycle of IP development, customization, and verification. Instead of manually modifying RTL for each requirement, SmartCompiler helps generate IP variants efficiently and consistently.

This allows SmartDV to configure IP for project-specific needs while maintaining a repeatable process for validation and delivery.

Why SmartCompiler Matters for Engineering Teams

SmartCompiler enables:

• Faster development cycles
• Reduced engineering overhead
• More consistent protocol compliance
• Optimized and repeatable IP generation
• Customization based on real project requirements
• A more scalable path for future IP variants

For teams building advanced SoCs, this helps reduce the risk that customization becomes slow, inconsistent, or difficult to verify.

How the SmartDV Customization Process Works

Start With the Right Foundation

SmartDV’s customization process begins with the right technical foundation. Customers can select from SmartDV’s portfolio of Design IP and Verification IP. Where needed, SmartDV can extend or adapt IP to meet specific design requirements.

This allows teams to avoid starting from scratch while still moving beyond rigid, one-size-fits-all implementations.

Define What the Design Actually Needs

Before customization begins, project requirements need to be defined clearly. This may include PPA targets, protocol requirements, interface specifications, feature needs, system constraints, safety considerations, and verification expectations.

Defining these requirements upfront helps ensure the final IP is optimized for the design rather than simply configured around default assumptions.

Customize, Verify, and Integrate

SmartDV engineers customize the IP using SmartCompiler and validate it through comprehensive verification methodologies. This is a critical part of the process because customized IP must still meet functional, protocol, and integration requirements.

For complex systems, SmartDV can also support pre-integration planning across related IP, controllers, interfaces, and verification environments.

Teams can explore SmartDV’s full Design IP and Verification IP portfolio to evaluate options for their architecture and verification needs.

Why Customizable IP Supports Long-Term SoC Strategy

Advanced Designs Are Becoming More Specialized

Emerging trends such as chiplet architectures, AI silicon, heterogeneous integration, advanced automotive systems, and edge computing are increasing demand for IP that can be adapted to specific architecture goals.

Generic IP often cannot meet the combined performance, power, area, and integration requirements of these systems. As designs become more specialized, customizable IP becomes a stronger differentiator.

Customization Supports Reuse Across Product Families

Customizable IP can also support long-term reuse. A team may need to use the same IP foundation across multiple products, but with different configurations, interfaces, features, or performance targets.

When IP is designed to be configurable from the beginning, it can be easier to adapt across product families and future platform revisions. This helps engineering teams build around a reusable foundation instead of restarting IP evaluation and integration for every new design.
