SVA temporal implication operators

Understanding SVA temporal implication operators in SystemVerilog

This question tests your understanding of temporal implication operators in SystemVerilog Assertions (SVA), a key language feature for formal property specification in hardware verification. It requires you to correctly interpret how antecedent and consequent sequences interact across time steps, and how implications constrain behavior in response to observed patterns.

SVA implications (both overlapping and non-overlapping) are among the most frequently misunderstood operators in assertion-based verification. Getting the semantics right is essential for writing correct monitors, scoreboards, and property specifications in any substantial testbench. Interviewers use questions like this to confirm you can reason precisely about when properties succeed, fail, or are vacuously satisfied.
