Several edge cases in the 2020.2 synthesis engine caused behavioral mismatches where simulated code did not match real-world physical logic. A notable bug involved multi-bit counters and conditional state expressions where upper bits failed to hold their logic state properly. : Apply specific tool updates or syntax constraints.
