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.
