Jeff (kinarfi) uploaded a file "4 GROUP.zip" to the group's Temp
folder, but there is no message yet to the group about it. I don't
know if you forgot to send one, or if it is just held up by today's
unreasonably slow Yahoo computers.
Your upload says "WHAT AM I DOING WRONG WITH MY BS250P BS170".
I think your keyboard's Caps-lock key is stuck. Either that, or you
are shouting.
Here is what's wrong.
Problem 1: When you created your custom NMOS and PMOS symbols, you
put the transistor name in too many places. In the Attributes, you
have
SpiceModel = BS250P
Value = BS250P
Doing that, causes the transistor to go into the SPICE Netlist like this:
U1 OUT-1 N002 N001 BS250P BS250P
Note that BS250P appears twice. It must be only once.
Remedy: Edit the two symbols. Remove the SpiceModel attribute (leave it blank).
Problem 2: You set the Prefix to "U". The U prefix is for lossy RC
transmission lines, but your models are subcircuits.
Remedy: Edit the two symbols. Change Prefix from U to X.
After saving both symbols, close and re-open the schematics.
Problem 3: Draft2.asc doesn't work because LTspice doesn't have a
2N7000 model in its library. But it has the 2N7002, which is similar.

Andy
