how to simulate electronics in matlab

Hello all,

Do you know how to simulate a simple digital (or mixed) circuit with Matlab?
I mean a circuit containing only a few discrete logic elements(and, or, nand ...), flip-flops and also some opamps, resistors and capacitors.
I don't mean a FPGA circuit(xilinx or other)!
Is there a kind of schematic editor with library of the above mentioned elements?
If you can upload some examples that will be great!

how to simulate a digital circuit on matlab

Hi kukurigu

Try:

There seem to be several that have a few simulation programs. Maybe something there.

There are many freebie/trial/demo circuit simulation programs out there that will probable better however.

can simlate digital circuits in matlab

if your target is to simulate your circuit, there are many good packages to do so. Regarding matlab I think you need the model of your devices and the Matlab will solve the equation that descripe the device functionality and give you the result. I remember that I saw a Text book deal with simulation of electronic devices using Matlab but unfortunately I did not remember the exact name.

how to simulate rlc circuits by using matlab

If u just want to simulate some simple circuits, u should look for a circuit analysis software - there are some demo version that u can use with a few discrete components.......

maybe this is book title? - "elementary mathematical and computational tools for electrical and computer engineers using matlab"

you need the models for some things but flip-flops, gates , and some electrical devices are implemented in simulink. Here you can simulate your system. For example a RLC circuit has a transfer function that you can simulate in matlab. There are better tools for simulate hybrid systems (as proteus orcad simplorer) if your system are electrical one. Simulinlk is better for complex systems with several different physical variables

If you need to do it in matalab use simulink. it's very easy. A complex digital system (as procesor ) can be modeled easy in simulink as a Finite State machine by using the stateflow utility.

More specific question better response.

I forgot it,



Search in the phorum the book :
"electronics and circuit analysis using matlab"

for simple analog circuits
