请问XILINX XC3030A和XC3030之间的应用差异是什么？

Y，
3000系列FPGA器件是Xilinx开发的第二个架构，它遵循2000系列，创建了公司和现场可编程逻辑行业。
在2000年之前，存在复杂性非常有限的可编程逻辑器件（PLA）（可能最多20个触发器和相关的栅极矩阵）。
A版本有较小的电路改进，并且是“缩小”（使用更先进的技术节点来降低功耗，并降低成本）。
那是25年前的事了。
半导体产业的悠久历史。
你是历史学家吗？
学生？
找到一些旧零件，并想知道你可以用它们做什么？
有一个旧的生产设计，需要建立更多？

以下为原文

y,
 
The 3000 series of FPGA devices was the second architecture developed by Xilinx, which followed the 2000 series which founded the company and the field programmable logic industry.
 
Prior to the 2000, there existed on programmable logic devices (PLA) of very limited complexity (perhaps a maximum of 20 flip flops and associated gate matrix).
 
The A version had minor circuit improvements, and was a "shrink" (used a more advanced technology node to lower power, and lower cost).
 
That was more than 25 years ago now.
 
Ancient history for the semiconductor industry.
 
Are you a historian?  Student?  Found some old parts and wonder what you can do with them?  Have an old production design and need to build more?

亲爱的奥斯汀，
非常感谢你的回答。你是对的，我有两个老电路，它们有相同的使命。
其中一个有XILINX XC3030A。
另一个有XC3030。
我试着理解为什么使用XC3030A，这些电路的区别是什么。
XC3030A的工作速度比XC3030快。
因此，他们希望通过XC3030A提高电路性能。
XC3030A如何为这个电路做出贡献？

Dear Austın,
 
Thank you very much for your answer.You're right, I have two old circuits which have same mission. One of them has XILINX XC3030A. The other one has XC3030. I try to understand why XC3030A is used, what is the differences of these circuits.  XC3030A works faster than XC3030. For this reason, they want to improve performance of circuit thanks to XC3030A. 
How does XC3030A contribute to this circuit?
