Topic: beginner question on spice - what's wrong ?
Body: Hi,
I'm trying to simulate a simple oscillator with TLC555 (ne555) from TI.
I can't have any good results. capacitor isn't charging . it's very strange.
What I am doing wrong ?
here comes the netlist, the MOD for TLC555 (from ti site).
I'm using spice 3f5 under linux.
thanks for youe help.
