From signals you can make copies, add signal, multiply signals,  etc.

Examples: maximal value of signals: 23>24>25

Pack bits:  23p12p22

Logic: 34and45and49

Also possible: connection of connection.

Connections must be separted by "comma": example;

45×33×2, 23-3,6p7,23or35

Unpack signal into bits:

Double click on signal opens menu.

If only, for example, bit 10 is interesting, make a copy of the signal and write bit(10). 

Additional, it is possible to substitude the original signal name by an other name.
