Practical ZYNQ China Replacement: How Much Changes Migrating from Xilinx ZYNQ to PBC7Z020G/021G

The original design uses Xilinx Zynq-7000 (XC7Z020) for the ARM-software-plus-FPGA-realistic-logic heterogeneous scheme, and now it must go domestic. Does swapping the chip mean rewriting the whole project, or only local changes? This article splits the migration of HWD7Z020 (XC7Z020-compatible) onto PBC7Z020G/021G into three layers — PS software, PL logic, boot and BSP — and breaks down the actual change volume, reusable parts and risk points.

Fudan Micro JFM7 vs AMD/Xilinx 7-Series: Can China FPGA Truly Replace Them?

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.
