What is a CKT file?
Printed circuit board (PCB) design created with CircuitMaker, a circuit layout and design program; can be used to create circuits and test them by running simulations.
CircuitMaker is no longer developed and has been replaced by Altium Designer, a electronic product design program. Altium Designer provides a unified product development interface and can be used for a more broad range of hardware design that CircuitMaker.
