SW for simulating Cortex M4 targets on pc

Hi all,

I am trying to find a third party software that will allow me to run my target code and interface (GPIO, peripherals) with another program like Labview that will model the entire system and provide a GUI.
Can someone point me to some options available?
My system is distributed, and it uses multiple LPC4078 chips and possibly some M0s as well.
Communication is mainly through discrete signals (GPIO) and serially via CAN bus.

Thanks in advance.

Cheers.

Writing a simulator for a very cheap mcu is not worth developing. If you can buy a dev board for less than $50 there are very few people who want to simulate - especially when no simulator is anywhere near 100% accurate. There are so many mcus with different peripheral sets from different vendors it's just too much effort to develop with a very small market.

Instead of simulating buy dev boards and develop in a real environment

Good point, many dev boards are well under $50.  I remember a LPC4337 dev board for $25, and the LPCLink2 4370 (which can be used as a dev board) for $20.

Thanks rocketdawg for your response.
I was hoping there is some software that works with specific MCUs from different vendors, to account for different peripherals.
I found something called TINA by DesignSoft, but their range of supported microcontrollers is very limited, and does not include ARM Cortex-M.

that might be hard.
You see, ARM just license the CORE to silicon vendors.
Then each vendor is free to create their own hardware blocks for peripherals.
A LPC CAN peripheral will be different from an ST CAN, or TI CAN, or any other vendors CAN.
An LPC CAN block may even be different from one product line to another. 
Peripherals is where the chip vendors add value.

There is one non-ARM vendor (nameless, of course) that provides a simulator for their parts.
they do this because their hardware debugging sucks unless you spend 400 bucks on their top of the line ICE.
And even then, the skids are a pain.
But their simulator is often more buggy than their hardware.
