I have a couple issues I'm having trouble with, I'm using orcad 16 and trying to simulate a simple circuit, it's basically two pulse generators VPULSE each going through a diode... I'm trying to "diode- or" two voltage sources... but I keep getting these large voltage spikes.... say if I set the pulses at 12V I get these 16V spikes... and then they settle to 12V here is my circuit, where V1 and V2 are 12 Volt pulses slightly offset from one another... I was especting to seee 12 V on the Vout regardless of whether V1, V2 or both were on
V1 O-----|>|------- D1 | |-------------O Vout | V2 O-----|>|------- D2
My other issue is, I try to set my pulses for 1 second each and then want my simulation to go to 3 seconds, but it takes forever to run through the simulation, does anyone know how I can speed that up.... can I change the sampling rate or something so it would fnish faster?
Much thanks J.
