RE: [ng-spice-devel] a useful device
That's why the resistor device has an optional parameter named AC which
specifies the AC value. You can make nice DC/AC switches by using resistors
with a DC value of e.g. 1Ohm and an AC one of 10gOhms and viceversa:
r1 dcpath common 1 ac=10g
r2 acpath common 10g ac=1
