make verilog 期间内存溢出导致无法生成代码 about xiangshan

我们之前在ubuntu 18.04的环境里面也遇到过这个问题，可以试一下配这个环境变量

export _JAVA_OPTIONS='-XX:-UseGCOverheadLimit -Xms256m -Xmx10g -Xss256K'

加上这个配置后可以完整编译了，谢谢！

我用虚拟机编译也有这个问题， 编译至少虚拟机需要多少内存呢？

这个界面停留了很久，build/XStop.v 这个文件也没有生成出来，这个是什么情况呢

Done elaborating 之后就会生成 Verilog 了，确实需要很久（我的电脑上就要差不多半小时），另外如果电脑内存不够的话可能会时不时卡在 GC 上导致特别慢，可以试试多等一会或者把内存调大一点。最小内存的话没试过，但最好还是给个 5-6 GB 以上的吧。
