Updated by Sergey Smolov over 5 years ago

  • Status changed from New to Open
  • Priority changed from Urgent to High

This bug is caused by 'PC_WIDTH' macro calls inside 'mips16/IF_stage.v' Verilog module. Now these calls are substituted by the macro's true value (8).
The problem will be fixed when moving to ANTLRv4 has been finished.
