Dec 19, 2025 · 2 min read · FPGA fabric is the “reconfigurable hardware area” of an FPGA—the big grid of programmable logic and routing that you map your design onto. Think of an FPGA as a city: Fabric = the city blocks + roads you can rewire. Your HDL/HLS design becomes “bui...

Nov 7, 2025 · 3 min read · Here’s a compact, engineering-oriented way to estimate “flexibility” of an FPGA interconnect—i.e., how easily (and with what headroom) it can route/timing-close a variety of netlists. 1) Define what you’ll measure Routability: how much channel width ...
