Xiangshan当下的编译是用的Scala FIRRTL Compiler还是Circt呢?

[Jerry-Tianchen]

Hi～
I notice that during the compilation, the main tasks are still running in Java instead of C++, I am thus wondering if Xiangshan is using the Scala-based FIRRTL tool for compiling... The Xiangshan repo version I am using is from Jan 8, 2024.

According to the previous discussion, it seems the chisel should automatically use CIRCT, right?

The Boom Core & Chipyard uses C++-based CIRCT so it only takes several minutes to complete the compile. Based on the compilation time of Xiangshan, it might still be running the JAVA-based FIRRTL-->Verilog process.

Based on your version, you may add MFC=1 when you make, and this is already set as default on current master branch.
