integrate analog and digital circuits in quartus prime

In a word, no.

Quartus supports FPGA/CPLD digital design only for Altera devices.

The included ModelSim simulator is a digital design simulator, it has no analog capabilites.

What you need for the analog portion of your design is something like LTspice and the appropriate device models that is a true analog simulator.

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.

Thanks very much for your clear information. What about using vhdl-ams? is it possible in ModelSim?

best regards

Hi,

as far as I know ModelSim Altera doesn't support AMS, but the full version does, see here: http://www.alteraforum.com/forum/showthread.php?t=2495 (http://www.alteraforum.com/forum/showthread.php?t=2495).

I once used SMASH, which is a free VHDL-AMS simulator: http://www.dolphin.fr/index.php/eda_solutions/products/smash/evolution_over_time (http://www.dolphin.fr/index.php/eda_solutions/products/smash/evolution_over_time).

What exactly is it that you want to do with VHDL-AMS? You said you want to "design both analog and digital devices"?

Dear GooGooCluster,

Thanks again for your help. Based on the information you gave me I will try SMASH (VHDL-AMS) or OrCAD/PSPICE (mixed signal schematic design and simulation).
