Same error message in this situation : data is input 16 bit, address is output 16 bit ``` var adr = (address and 0b0000000001111111) address = (data and 0b1111111110000000) or...

There's no accessor in my second case, it's just an AND between numbers. Plus I've already tried something like : ``` var adr = address address = (data and 0b1111111110000000)...

Here is the component stripped from all the circuitry : [Copy of inc dec.zip](https://github.com/user-attachments/files/16080810/Copy.of.inc.dec.zip) It's an incrementer/decrementer and the limit6 input limits the carry propagation to the bit 6, so...

It's fine when i work with an intermediate variable instead of the output : ``` if ('carry in') { var adr = 0x0000 if (decrement) adr = data - 1...

Logisim-evolution for example does that for each pin individually, not globally in the preferences :  Your solution is elegant and would be fine in my case for the PRE...

ASAP ? No just a joke :) I've no "release date" yet, it's a middle term project I have as a hobby : I'm recreating the Z80 CPU from schematics...

I will when it's finished, but there's still a long way until completion so it won't be tomorrow 😄 Thanks for your reactivity by the way !

OK I was asking myself 😃

For the floating output, you can color blue what will be the "closed switch" from S to D, that would be fine as when a transistor's gate is open the...
