What are IP Cores in Semiconductor Design: Types & Advantages

Introduction

There is one term that is making the life of a semiconductor design engineer easier. This term is so versatile that it has a business model today.-IP cores.

In semiconductor design, an IP core, short for Intellectual Property core, is a pre-designed and reusable block of logic or functionality that serves as a building block for creating complex chips. Think of them like Lego bricks for chip design!

IP cores are the digital building blocks which overlooked by the end-user, play a pivotal role in shaping the functionality and efficiency of any processor that comes out in the market. This article delves deep into the essence of IP cores, their types, advantages and challenges. From the fundamental distinction between soft and hard to exploring the competitive landscape of the semiconductor IP market, we’ll uncover the role these blocks play in driving innovation and progress in the semiconductor industry.

What are IP cores?

They are like ready-made pieces of a puzzle that chip designers can license to use in their own designs.

As technology advances, chips are becoming more complex, packing numerous functions into a single unit, known as System on Chip (SOC) designs. In these designs, pre-designed IP cores play a crucial role as they provide essential building blocks for various functions.

Functionality: An IP core can represent various functionalities, including digital logic (performing calculations), analog circuits (processing continuous signals), or even an entire sub-system like a memory controller or a communication interface.

Reusability: The key benefit of IP cores is reusability. Designers can incorporate these pre-verified blocks into their chip designs instead of reinventing the wheel for every single function. This saves significant time and effort.

Licensing: IP cores can be licensed from third-party vendors or developed in-house by a company for its own use.

Types by core

There are two main types of IP cores: soft IP cores and hard IP cores.

Designers create soft IP cores using HDLs (Hardware Description Languages) like Verilog or VHDL. Conversely, designers craft hard it is using physical design techniques and typically deliver them as physical layout databases.

Soft IP cores – crafted using hardware description languages (HDLs) like Verilog or VHDL, are usually provided as synthesizable source code. This means designers can adjust and tailor them to meet their unique needs.Their value lies in their flexibility and adaptability. It is making them well-suited for diverse applications.

Example – Soft processor IP cores, like the ARM Cortex-M series or RISC-V cores, offer programmable computing capabilities that designers can customize for various applications.Designers can adjust parameters like clock speed, cache size, and instruction set architecture to meet specific performance and power requirements.

Hard IP cores -It employ physical design techniques and are often delivered as pre-made physical layouts or netlists. They optimize for performance, power usage, and size, ensuring high efficiency and reliability. However, they offer less flexibility compared to soft IP cores.

Example – example of a hard IP core is the SerDes block. SerDes is a key component in high-speed communications to enable rapid data transfer. It converts data between serial and parallel interfaces bidirectionally. The purpose of this process is to provide a high-speed data path.

A SerDes block is often provided as a hard macro by semiconductor vendors. This means the physical layout, including transistors, wires, and other components, is already optimized for a specific manufacturing process.

What is Semiconductor IP business?

The Semiconductor Intellectual Property (IP) Market is where pre-designed and pre-verified blocks are bought and sold for use in applications.

The Semiconductor IP Market is highly competitive, with several key players offering a wide range of IP components and solutions. These players include semiconductor IP vendors, IP design houses, and foundries. They compete based on factors such as the breadth and quality of their IP portfolio, technological expertise, customer support, and pricing strategies.
