WebSep 3, 2024 · 1. co is X (unknown) because it is a continuous assignment to an expression dependent on current, which is X. current is X because you declared it as a reg, and reg types default to X at time 0, and then you never assign it to a known value. Your testbench always drives rst as 0. This means line 8 is never executed.
