    Hi,

    I am currently doing with a project about 555 IC Timer simulation using MATLAB Simulink. I have attached my 555 IC Circuit in this mail in first attachment and the second is the 555 IC Circuit with Voltage Measurement. (Both in MATLAB Simulink file)

    Actually, the problem is my 555 IC Circuit model only generate the output start from S-R flip-flop after the simulation. It seems that the signal cannot pass to the two Comparators (OPAMP) and to the S-R flip-flop, this caused the scope can only display the information from S-R flip-flop which initially set to '0'. Can someone help me to check what problem that occured with my 555 IC Circuit? Is the connection problem that caused the signal cannot go through the comparators or the problem caused by components.

    Thank you for your help and information.

    Can you post the schematics via a jpg or gif? Not everyone uses MATLAB.
