According to a widely available ngspice handbook available here:
http://www-ti.informatik.uni-tuebingen.de/~bernauer/lehre/ti-1-0506/spice/docu.html you need to name the switch model SW, not VSWITCH. Give the handbook a read, it's not too bad. Stuart On Thu, 16 Nov 2006, nano schultz wrote:
Hello, I'm trying to simulate a switched-capacitor model, but however ngspice can't recognize vswitch model.
