In this simulation program can't resolution all things so I put switch between pin 7( discharge (npn) and it's resists 10k pin 2( trigger (pnp) is conect with pin 6 (threshold (npn) to pin 7 by 100k resistor the reset pin conect with positive by 100k above of this design I Make  MULTIVIBRATOR by this 555 you can do other's. ..notice change switch before start simulation Makes program show this message "can't find solution " so turned it to empty side  if you have any idea share with me I will be thankful. .walied all shareef. وليد الشريف أبو محمد
