Note that particular implementations of regular expressions interpret backslash differently in front of some of the metacharacters. For example, egrep and Perl interpret unbackslashed parentheses and vertical bars as metacharacters, reserving the backslashed versions to mean the literal characters themselves. The assertions in the checklist are all valid SystemVerilog 2005. They should work in both simulators and in formal verification engines, but the with an emphasis on simulation performance.
