Help!!! Spice Netlist
« on May 27th, 2013, 08:44 PM »
Im trying to test a circuit made from Diptrace in LTspice and im having a problem with one of the models. Listed below is the error log and subroutine

Circuit: *** Component Net List Start ***

Error on line 53 : opmodel1.cir - opamp model single-pole
    Unable to find definition of model ""
O: lossy line series resistance not given, assumed zero
O: using linear interpolation because trytocompact option specified
O: lossy line series inductance not given, assumed zero
O: lossy line parallel capacitance not given, assumed zero
Fatal Error: O: At least two of R,L,G,C must be specified and nonzero

Theres alot of this i dont understand so any help would be greatly appreciated.

Great to see you working with LTSpice. there is a competent usegroup at http://tech.groups.yahoo.com/group/LTspice/

they are competent and responsive :-)

I´m not that much in the details of LTSpice that I can support you by myself. I´m not using Netlists that much.

Cool to see you here as a member!
