The most common FPGA selection mistake: picking a chip model first and reverse-engineering the requirements, or looking only at price without resource margin. The correct order: define bandwidth needs (transceiver pairs) → calculate logic resources (LC/DSP) → pick the cheapest board that meets both. This article turns Duyuan's main product line into a decision matrix you can reuse.
Domestic substitution is not as simple as "swapping one chip." Many teams only compare unit price and logic resources during selection, only to discover once migration begins that toolchain, IP cores, PCB layouts, and engineer learning curves all need to be recalculated. This article gives you a TCO (Total Cost of Ownership) framework that itemizes every cost of migration, so you can decide whether it is worth doing.
One of the most frequent questions Duyuan Electronics receives over the past two years is: "We used to use Xilinx XC7K325T, and now we need a China-based replacement. Can the Fudan Micro JFM7K325T be dropped in directly? How much code do we need to change? Do we need to redesign the PCB? How much performance do we lose?" This article puts three mainstream model pairs from the Fudan Micro JFM7 series and the AMD/Xilinx 7-series side by side, and explains exactly to what extent a "drop-in replacement" really holds.
Over the past three years, domestic substitution in the FPGA industry has gone from a slogan to real orders. This article gives a 2026 horizontal comparison of mid-range Chinese FPGAs from Pango, FMSH and Anlogic.
