i see that the HW simul. doesn't let me connect some internal chip output to several gate inputs
for example - on ALU:

Mux4Way16(a=xandy ,b=xaddy ,c=nxandy ,d=nxaddy , sel[1]=no ,sel[0]=f ,out=out );
Mux4Way16(a=xandy ,b=xaddy ,c=nxandy ,d=nxaddy , sel[1]=no ,sel[0]=f ,out[15]=ng , out[0..14]=zrox );  
       
since ng bit is driven from the ALU output simply by looking on the msb,
i expected it to be possible to just "draw a line" to that output pin

See example in Appendix A.5.3. You can do this all in one statement.
