Ltspice Definition and 54 Threads

Hi everybody. how r u. i'm using linear technology's LTSpice IV to simulate my dc/dc switching power supplies. for that I'm using the chips from the same company. the problem is that when i simulate the circuit using LTSpice IV the simulation speed that it shows is only 25microsecond/s which...

EDIT: PROBLEM SOLVED! I found a model on a website of the manufacturer! Next, I need to hunt down this 5.1 V Zener. Hey. I'm designing a full-wave bridge rectifier regulated by a Zener, and on of the project requirements is an LTspice simulation(not to mention it's a good place to start before...

I use LTSpice, and vaguely remember there was a way to make a voltage (or current) source depend on either another source in the circuit, or to follow some function of time. I think it's either a source parameter, or a command line placed in the schematic. Does anybody know how to do this...
