Logic chips: Open source FPGA with 12 nanometer technology

The “Laboratory for Nano Integrated Systems” at the University of Utah (UofU LNIS) had an open FPGA with 12-nanometer technology produced by the chip contract manufacturer Globalfoundries. In order to program the “First Reconfigurable Open-source Gate-array” (FROG), you don’t need any proprietary software like with FPGA chips from AMD / Xilinx and Intel / Altera. Rather, the LNIS lays down the…
