I downloaded the files from internet: anl_misc.olb anl_misc.lib and copy them to the directory: C:\Program Files\OrCAD_Demo\Capture\Library\Pspice However, when I simulate a circuit of 555. there is an errro: ERROR -- Subcircuit 555B used by X_U6 is undefined Does anyone know what is going wrong? Thansk a lot.

My problem is that my PWM output wont go down to 0 but to 0.1.. do you know what might be the problem? The circuit is like the one below.. any suggestions?
