Any TopSpice Users Here?

I have an OpAmp model out there that runs fine on PSpice, LTspice, HSpice, etc., but balks on TopSpice.

The error report, from the TopSpice output file is:

GSw_Sw3 N_22 -VB VALUE {((TANH(9.485/0.1*(V(SHUTDOWN, + GND)-0.5))+1)/2)*(V(N_22, -VB)/1)}

0*ERROR*: mismatched parentheses in above expression check result= -1

0*ERROR*: loading VALUE behavioral expression token list. Error# 1

The parentheses ARE NOT mismatched.

This error only reports for lines with a continuation (+ in first column... which just caught my attention, because, at least in the output file, the + is showing in the second column, while, in the subcircuit library, it's in the first column.

Anyone with first-hand experience with TopSpice?

Thanks! ...Jim Thompson

I love to cook with wine.     Sometimes I even put it in the food.

Try adding extra () around the inner expression?

{ ( ((TANH(9.485/0.1*(V(SHUTDOWN,+GND)-0.5))+1)/2)*(V(N_22, -VB)/1) ) }

Aha! To force it to _continue_ to a matching closing? ...Jim Thompson

Solved... via return E-mail from Penzar: TopSpice does not like for now, being updated) node names beginning with a math operator, thus a node name -VB makes it throw up.

Personally I'm going to adopt a policy of no node names with + or - in them, thus IN+ will become INP. ...Jim Thompson
