Gang, Having trouble with a very simple netlist that has worked before on other versions of ngspice but not now after updating to version 21plus.
At issue is the lossless t-line element. It seems to have no output. See netlist below. Has anyone else had a problem with it? Thanks, Roger Traylor T-line test *input source with 2ns delay, 1nS edges, 20ns pulse width, 41ns cycle time Vin vin 0 1.0 PULSE(0 1.0 2e-9 1nS 1nS 20e-9 41e-9) *source output impedance rsrc vin tline_in 50 *the transmission line, 50 ohm, 2ns electrical length t1 tline_in 0 tline_out 0 z0=50 td=2ns *termaination at end of T-line rload tline_out 0 1000Meg .control op tran 100ps 40ns plot V(tline_in) V(tline_out) xl 1ns 40ns .endc .end _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
