#1 eFPGA: most customers, tapeouts, nodes, sizes, options, metal stacks

Flex Logix has been innovating eFPGAs for 8 years
  • 25 designs working in Silicon
  • Array sizes from 1K to >2M LUTs with DSP and BRAM options
  • Use the fewest lower metal layers so we are compatible with the most metal stacks

EFLX eFPGA Available for 12, 16, 22, 28 & 40nm
7nm in Design and 5nm Next!

EFLX 4K eFPGA in both Logic and DSP versions are available on the following process nodes:

  • TSMC 12FFC+/FFC/16FFC+/FFC/FF+ silicon proven, evaluation board available
  • TSMC 28HPC/HPC+ silicon proven, evaluation board available
  • TSMC N6/N7: In Design
  • GlobalFoundries 22FDX in design for 2022 availability.
  • GlobalFoundries 12LP/LP+ silicon is validated and an evaluation board is available
  • GlobalFoundries 12LP Rad Hard design also available 
  • Sandia 180nm was a proprietary port for Sandia National Lab’s own 180nm wafer fab 

EFLX eFPGA can be implemented on any CMOS process node on demand. We can work in parallel with your team as we are porting to a new process and provide preliminary views.

TSMC’s Partner of the Year

We are TSMC’s first eFPGA IP Alliance Partner and the TSMC Partner of the Year for excellence in eFPGA IP

Flex Logix eFPGA Evaluation Design Kits Available

  • Define how much eFPGA fabric you need
  • Determine performance in several process corners
  • Evaluation boards available as noted below
Demo Videos and Product Brief information is available in the Resources.
Contact us here for pricing or an evaluation design kit.

EFLX Evaluation Boards

Evaluation boards are available for EFLX eFPGA implemented on TSMC28HPC, TSMC16FFC and GF12LP.  Boards are controlled by PCs; you can compile and download your verilog into the eFPGA to measure speed and power.


Contact here for prices for purchase or for short term evaluation.

Emulation Models for EFLX eFPGA

  • Emulation models for EFLX eFPGA are available now for both Cadence Palladium and Mentor Veloce platforms.
  • Any array size with any mix of DSP and Logic tiles can be emulated, along with various BRAM configurations.
  • These models have been used by Flex Logix in design of our own InferX X1 SoC and by our customers for design of their SoCs.
