errro和fatal指向同一行，找不到错误在哪

Error-[CNST-NAE] Constraint null array error
./src/riscv_instr_sequence.sv, 241
  The constraint solver failed when accessing a null array cfg.reserved_regs.
  Please make sure array cfg.reserved_regs is allocated properly.

UVM_FATAL ./src/riscv_instr_sequence.sv(241) @ 0: reporter@@main_program [main_program] Check failed (jump_instr.randomize()) Cannot randomize jump_instr

麻烦各位大佬给看看 感谢感谢

应该是你约束有冲突，仿真器解不了

在你的log里，从报错的位置往上看，会有提示哪个约束冲突
