This directory holds a SPICE netlist with SPICE2 POLY constructs incontrolled sources as typically found in vendor models.  The circuitis just a two-stage transimpedance amp using an AD8009,along with some slow components (AD780 and OP177A) to set biaspoints.  Vendor models are used for all active components.Successfully running this test shows that you have successfully builtthe XSpice stuff with the POLY codemodel, and that you should be ableto simulate SPICE netlists with embedded vendor models.To run this netlist, just do the following:[localhost]# ngspicengspice 1 -> source output.netngspice 2 -> runngspice 3 -> plot Vout2(Note that when you read in the netlist, you will get a bunch of warnings saying stuff like:Warning -- Level not specified on line "()"Using level 1.Also, ngspice will complain about:Error on line 50 : r:u101:1 u101:40 0 1e3 tc=7e-6         unknown parameter (tc)Error on line 283 : .temp 0 25 50 75 100         Warning: .TEMP card obsolete - use .options TEMP and TNOMYou can ignore all this stuff . . . .)You should get a pop-up window showing two square pulses (the secondsmaller than the first) with a little bit of overshoot on the risingand falling edges.This stuff was done as an adjunct to work on the gEDA project.Information about gEDA is available at http://geda.seul.org/ .Please direct all questions/suggestions/bugs/complaints about XSpiceextensions to ngspice to Stuart Brorson -- mailto:sdb@cloud9.net.6.23.2002 -- SDB.
