    I want to generate 50% duty cycle 1kHz square wave using CD4047 IC in Proteus..but every time I simulate error comes plz help me what is main problem in this simulation file..I am using Proteus Version 8
    Error which Proteus shows

    No model specified for U1
    Simulation failed due to partition analysis error

    The 4047 does not support simulation on the ISIS so as in my version 7 proteus.

    When you pick device, on the right top corner, it says "No simulator model" for 4047.

    It was only used for drawing schematics, So bad luck for you this time.

    this is because you choose a component which has no simulation model for proteus....... while writing cd4047 in pick component choose another component which has schematic or spice model...

    First, update to Proteus 8.5.
    Second, sometimes there are more than 1 IC's of name "4047", check if any of them have a simulation profile.
    Third if there is no simulation profile, try to replace "4047" with a similar IC in Proteus. Like its mentioned in the previous post.
