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

To force it to _continue_ to a matching closing? ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

Personally I'm going to adopt a policy of no node names with + or - in them, thus IN+ will become INP. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.
