总而言之：像 FK33 这样的大型 FPGA 由于易于布局和布线，因此在设计复杂性有限的情况下具有优势。如果预算允许以 250 美元左右的价格购买二手 FK33，它可以为许多项目提供足够的资源，例如 439680 LUT、879360 FF、672 BRAM、2880 DSP、320 URAM 和 8GB HBM。 FK33 包含一个 FTDI 芯片，用于简单的 JTAG 闪存、通信和管理。作为初学者探索 FPGA 的世界可能具有挑战性，因为 Xilinx 的工具在性能和用户体验方面优于竞争对手。 Quartus 或 Lattice 的工具等其他选项可能分别排名第二或第三。对于那些设计 PCIe 设备但希望避免构建必要的 PCIe IP 的人来说，Xilinx 提供了卓越的结果，并通过大量可用示例和兼容的开发板提供了更好的可访问性。

> I definitely do not need a very large FPGA

Bigger is better here - even if you don't use the LUTs/FFs, the tools have a much easier time placing/routing a relatively small design into a huge chip.

If your budget is $220ish, I would buy a used FK33 without a doubt for $250. You can use the Vivado trial (and keep renewing it.)

https://discord.gg/MynAgXK is Dream Escrow - lots of good/safe listings in there.

439680 LUTs, 879360 FFs, 672 BRAM, 2880 DSP, 320 URAM, 8GB HBM is plenty to work with.

The FK33 also has an FTDI chip onboard for convenient JTAG flashing, comms, and management.

> though navigating this space as a newbie is quite hard

This space is all about the tools: Xilinx is head and shoulders above everyone else. Quartus might be second, Lattice's tools are absolutely terrible (but open-source workflows exist for some of their chips.)

If you're designing PCIe devices and not wanting to build the PCIe IP, Xilinx's is absolutely the best in that department as well. There are more PCIe examples and boards for Xilinx chips than probably every other manufacturer.
