Firrtl compiles too slow with MediumBooms config

Open shinezyy opened this issue 5 years ago • 0 comments

Recently, I tried to build a medium boom for performance test. It takes 80+ minutes for firrtl to generated the verilog source code. I also built it from this boom-template from scratch without local modification, and ended up with similar results.

The I found that firrtl complie time is related to the size of Load Queue. Following table lists my results:

Load queue entries: Total FIRRTL Compile Time

  • 12: 126s
  • 13: 187s
  • 14: 387s
  • 15: ???
  • 16: 80+ minites
