integrate analog and digital circuits in quartus prime

Hi,

Quartus is an IDE for PLD (FPGA/CPLD) development, i.e. it allows you to create/edit HDL code (VHDL/Verilog) and IP, parametrize subcircuits on your PLD, synthesize the design, program it into the PLD, and debug the PLD (e.g. using SignalTap).

It is not a generic electronics design tool. It is limited to PLD devices from Altera. The most "analog" Quartus can do is parametrize the PLLs on your FPGA.

It sounds like you're looking for some schematic and layout editor, or some circuit simulation tool, for which I'd suggest KiCad and LTspice as a starting point, but Google knows many other, and many more sophisticated.

Best regards,
