A property is called “until property” if it uses one of the below until operators. until. s_until. until_with. s_until_with. Until properties are categorized as Overlapped & Non-overlapped and Strong & Weak. So overall four different forms of until properties exist.

WebBecause SystemVerilog assertions evaluate in the preponed region, it can only detect value of the given signal in the preponed region. When value of the signal is 0 in the first edge and then 1 on the next edge, a positive edge is assumed to have happened. So, this requires 2 clocks to be identified.
