Hi, I want to use 555 timer in Orcad pspice 9.1 (student version).
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.
