How to Match Strings in SystemVerilog Using Regular Expressions

http://www.testbench.in/SV_04_STRINGS.html WebVerilog’s variable types are four-state: each bit is 0,1,X or Z. SystemVerilog introduces new two-state data types, where each bit is 0 or 1 only. You would use these when you do not need X and Z values, for example in test benches and as for-loop variables. Using two-state variables in RTL models may enable simulators to be more efficient.
