Faststream Technologies provides significant cost savings, performance enhancement, and product assurance in FPGA to ASIC conversation. Our customers have been able to reduce system costs considerably by successfully substituting their high-cost FPGAs with drop-in ASIC replacements in various applications. In most cases, higher performance, lower power, better thermal performance, and improved radiation immunity can be achieved in the ASIC. We supply a parallel development path for FPGA development. This leverages the inherent flexibility for developing a new generation wireless connectivity of an FPGA during the development phase while accelerating the path to low-cost production with an ASIC.

Faststream’s design Engagement 


  • Faststream Technologies has worked on more than 500 IP and IP subsystems to support IP replacement or customization within the FPGA-to-ASIC conversion process.
  • Worked on Micro-Program Sequencing Engine for executing quick circuit function 
  • We have completed ASIC/SoC design flow and methodology
  • We have worked on an SoC evaluation platform for software and hardware co-development and system evaluation in the early stage

Faststream offers the following types of conversion 


FPGA Replacements

When 1 FPGA needs to be converted into 1 ASIC with pin-to-pin compatibility


Key Features 

  • Faststream Technologies performs a turnkey design from the FPGA RTL code. 
  • Pin-to-pin compatibility. 
  • Faststream provides QML parts using its Rad Hard 0.5um or 0.35um ASIC libraries and technology. 
  • Short cycle time (4-6 weeks from order entry to prototype delivery). 
  • Low NRE or no NRE depending on flight production quantity. 
  • No additional cost such as burn-in boards, qualification parts…


FPGA migration
  • When there is no pin-to-pin compatibility
  • When 2 or more FPGAs need to be converted into a single ASIC (multi-conversion).
  • When additional features are requested on the original FPGA design.
  • This solution is closer to the development of an ASIC which is based on the design as validated by the customer with the FPGA. 


Faststream Technologies undergoes  the following stages of FPGA migration 

  • The customer performs the Front-End design using the appropriate libraries in 0.5um, 0.35um, or 0.18um ASIC families. 
  • The customer delivers an ASIC net-list, formalized by a Logic Review. 
  • Faststream performs the Back-End Design, formalized by a Design Review. 
  • The package is selected from Faststream’s preferred package list (all space qualified). 
  • Faststream provides QML parts using the selected libraries and technologies.

Our Customer Design Toolkit: 


  • Gate and cell-based standard cell, compiled memory, IO, and analog IP for synthesis and simulation.
  • Logic rules checkers.
  • Tester rules checkers.
  • All design kits available via website download.
  • Design-for-test guidelines and requirements.
  • Design kit manuals.
