Hello, thanks for your help. But meanwhile I have seen, that I have been wrong. There was an general problem in the CMOS circuit. Both versions (with subcircuit and without subc) don´t work correctly. When the Input 1 is High and Input 2 is low, the output is high (correct). But vice versa, when Input 1 is low and Input 2 is high, the output is low. Unfortunately, when I simulated the XOR, i used the first (correct) combination for the circuit without subcircuit, and the second (wrong) combination for the subcircuit version…….. and so I thought the problem was caused by an mistake in the realization with subcircuit. I´m sorry…….
Greetings
