staff.ustc.edu.cning on standardizing SystemVerilog in 2001, additional issues were identified that could possibly have led to incompatibilities between Verilog 1364 and SystemVerilog. The IEEE P1364 Working Group was estab-lished as a subcomittee of the SystemVerilog P1800 Working Group to help ensure consistent resolution of such issues.
