Hello, I tried to create a gschem-symbol for an operational amplifier (MAX427). I wanted to follow the guidelines given in the "symbol creation guide" so in stead of providing power pins I added the appropriate net-attributes. The device has two pins used for balancing the offset.
I experienced two problems while using the symbol: 1. The spice-netlister "gnetlist -g spice-sdb" does not list the power-pins which are essential for the .SUBCKT-file to work. I downloaded it from the Maxim-Homepage. 2. The spice-netlister lists the offset-balancing pins that are not supported by the model-file that I downloaded. I see several possibilities to fix the two problems like: -providing power pins -deleting the offset pins (that I don't use anyway) -fixing the spice-netlist by hand But none of the solutions really satisfies me. What is the "official" solution to the two problems? How can I get one(!) gschem-symbol for the device that works with the spice-netlister as well as with the pcb-tool (eventually using the offset-pins)? Thank you very much for every help and have a happy new year! Lars Friedrich student -- Germany
