Benchmarked results
- Same Ubuntu SD card: U-Boot, kernel, devicetree boot straight away
- PL bitstream (PCIe x4 Gen 2 DMA design) downloads and runs at 3.8 GB/s—no recompile
- 72-hour temperature cycling –55 °C ↔ +125 °C: zero reboots, BER < 10⁻¹²
Three-step swap
- Remove XC7Z045; place JYX4S045
- Flash original BOOT.BIN & bitstream
- Power up—all peripherals recognized, performance matched
Bottom line
Everything the XC7Z045 does, JYX4S045 does identically—while adding wider temperature, shorter lead-time and >30 % BOM savings. Stop waiting, start shipping.
