没有源代码可以过时的FPGA设计迁移？

坏消息是你必须从头开始重新设计。
没有更新的设备与Spartan 2具有比特流兼容（甚至引脚兼容），并且没有软件可以修改比特流以在更新的设备上工作。
好消息是，您已经足够早地发现问题以实际处理它 - 而不是在Xilinx向您发送“产品不再可用”电子邮件时感到恐慌。
Xilinx为您提供为期两年的通知期。
他们会宣布他们计划停止生产，然后一年后他们会宣布你需要下订单的最终订单，然后一年后他们就会停止接受这些芯片的任何订单。
我建议借此机会研究系统如何从更新的芯片中受益。
许多旧设计都有FPGA，专用处理器，可能是专用DSP等。如今，像Zynq这样的单个集成芯片可以完成所有这三个任务，从而降低成本和PCB空间。

The bad news is that you're essentially going to have to recreate the design from scratch. There is no newer device that is bitstream-compatible (or even pin-compatible) with the Spartan 2, and there is no software that can modify the bitstream to work on a newer device.
 
The good news is that you've found the issue early enough to actually deal with it - rather than panicking when Xilinx sends you the "product is no longer available" email. Xilinx gives you a two-year notice period. They'll announce that they're planning to stop production, then a year later they'll announce that you need to place final orders for the parts, and then a year after that they stop accepting any orders for those chips.
 
I would suggest taking the opportunity to investigate how the system could benefit from a newer chip. Many old designs had an FPGA, a dedicated processor, maybe a dedicated DSP, etc. These days a single integrated chip like a Zynq can do all three roles, for much lower cost and PCB space.
