Chiplets Built with Speedcore eFPGA IP

Speedcore™ eFPGA IP can be deployed in various form factors including being integrated into a customer defined chiplet that can be deployed in a system-in-package (SiP) solution via silicon interposer or similar interconnect technology. Designers can fully customize the amount of logic, DSP blocks, and memory in the Speedcore eFPGA to match their application requirements.

The chiplet solution allows designers to reduce the board space required and realize new integration possibilities compared to a standalone FPGA solution. With a custom Speedcore eFPGA IP based chiplet solution, designers need to specify the interconnect technology between the chiplet and their ASIC die.

Benefits of Chiplets with Speedcore eFPGA IP vs. Bare FPGA Die Integration

Traditionally, designers who wanted to develop an integrated ASIC and FPGA solution were required to purchase bare die from an FPGA supplier, but there are challenges to this approach:

  • FPGA suppliers do not typically support bare die business because it requires custom processing and testing.
  • Standalone FPGA devices typically do not have the I/O structures required for system-in-package integration.
  • Standalone FPGA devices are not optimized for these type of applications, which leads to excessive power, larger packaging requirements and inter-die bandwidth limitations. 

On the other hand, by using a chiplet built with Speedcore eFPGA IP, designers can realize benefits such as:

  • Lower power and cost by only including the specific and required functionality for their application.
  • Optimized interfacing between the chiplet and ASIC for maximum bandwidth with minimal latency.
  • Smaller form-factor packaging based on a size-optimized eFPGA IP chiplet.

Benefits of Speedcore eFPGA IP Chiplets vs. Monolithic eFPGA and ASIC Integration

Designers who are looking for the highest level of integration can choose to develop a monolithic ASIC (single die) which includes Speedcore eFPGA IP. However, in some applications the monolithic integration does not allow for product flexibility that is possible with a chiplet-based approach. 

By using a eFPGA IP based chiplet, designers can realize benefits vs. a monolithic eFPGA ASIC solution, such as:

  • Companies can create unique product solutions (different SKUs) without the FPGA chiplet that have lower cost and lower power in the cases where FPGA flexibility is not required. 
  • Support different process technologies in the cases where the optimal process technology for the ASIC is not optimal for an embedded FPGA. Examples are ASICs built with mixed signal technology or ASICs built on technology where the eFPGA IP is not available. 

Getting Started with Speedcore eFPGA IP Chiplets

The design process used to develop Speedcore eFPGA IP chiplets is the same as developing an ASIC with embedded Speedcore eFPGA IP. This proven design flow makes it easy to develop a Speedcore eFPGA IP chiplet solution that leverages established tools and processes.
