This code may raise an error caused by DC's bug. We cannot use a type imported from an interface port as a return data type.

Cadence Xcelium may have an issue with resolving a function reference at this kind of location so I've uploaded another workaround to add the explicit scope tnoc_pkg::.

Can you add a space before a closing bracket ) to align position of a closing bracket to 2 space tab position?

@taichi-ishitani The 1st change on
env/fabric/top.svis not so good because it means we cannot use modport with multiple interface instances but I heard this is the only solution to elaborate this kind of code with Xcelium.The 2nd change on
rtl/common/tnoc_packet_if.svis what you wanted to do here but you didn't do so. I think it may cause some problem with Synopsys VCS. I'd like to hear your opinion on this.
