openxiangshan / fudian Goto Github PK

在pipeline分支上，根据README进行操作，执行到 make all_tests 这一步会报错。
错误如下：

Hi, there are some errors when I tried 'make all_tests', any solution?

Hi, we are trying to reproduce some of the floating-point bugs in Nan Hu to verify our internal product.
We checkout the nanhu design at: c067e65501c4d8dd61f010176acd9161272b9c92.

However, as I'm now trying to run fudian (43474be), I'm running into errors like below:

Am I missing something?

看到这个repo，包含的源代码，是scala？没看错吧。想了解一下，为什么是用Scala来实现，而不是传统的c/cpp, 或者是新潮的Rust等。

I’m not sure if I understand it correctly. Please correct me if I’m wrong. Are there any registers in FADD? I understand that there is a near path and a far path, but if you expect everything to be done in a single cycle, then the timing (critical path) is always determined by the far path. In that case, it seems it does not make sense to have two paths.
