Hello everyone,

I would like to set a delay with rising and falling edge (turn-off and turn-on), which Bibliotek can do something like that

thank you

Hi,

You can check the implementation of the turn-on delay block by right-clicking the component and selecting “subsystem->look under mask”. Further, if you right-click the component and select “subsystem->break library link” you can also change the underlying implementation.

If I understand you correctly you would like to do something like in the attached model? The “monoflop” block from the library might help you building up what you want to achieve.

Best regards,
NF

Hi,

If the upper waveform is not deterministic and known in advance the lower pattern can not be generated. I guess you want this related to pulse width modulation?

If so, you can use a symmetrical PWM block from the PLECS library and just modify the input index m of the block. Similar to the attached model.

Best regards,
