I have been experimenting with values recorded using a multimeter versus the voltages (rms) simulated using capture. I simultaneously setup a circuit using a breadboard and draw the exact same circuit on Pspice. I don't really have a particular circuit in mind. But I am sure I can set something up if it would help explain my problem.
Most of my component values have been extremely close to one another, such as resistors and capacitors. However I have hit a sour patch with the 555. It is not within a reasonable range. Not even close. The last test reported an error of about 45%. The breadboard pin 3 output voltage doubled the RMS Pspice voltage. Not good!
Is this normal? Is there anything that can be done to tighten up the Pspice component tolerances for IC's? I would like to use the program to its fullest, if it will let me!
Thanks for the help.
