To the newcomer to microcontroller development it is often not clear how all of these different components play together in the development cycle and what differences there are for example between starter kits , emulators and simulators. With this article, I'll try to give a short explanation of the different tools involved in the microcontroller development cycle, with a particular focus on the different emulator types and their advantages and disadvantages.

A hardware-software co-simulator for embedded system design and debugging
Emulation is used much earlier than traditional FPGA prototyping in the verification process. For example Simulation acceleration is considered as soon as major blocks of SoC are available.
For this reason advanced debugging capabilities are needed to trace problems and find bugs while running emulation instead of rolling back to pure HDL simulation. The HES-DVM supports two kinds of debug probes, which are static and dynamic ones that enable setting desired tradeoff between speed and visibility. Debug probes are sampled using one of design clocks and user can change at runtime which one to use.
Debugging data is acquired from the emulator board using fast PCIe host interface. The Static Probes feature is realized as the on-chip logic analyzer and so it provides features characteristic to this kind of tools. Static probes have to be selected during design setup flow before running synthesis, hence the static term. Static probes are organized in data and trigger groups that can be selected and configured at emulation runtime.
Additionally, the user can tweak debugging process via probes qualification expression or specifying the time range when samples are captured. In any case the ALA assures no sample dropped off as emulation clocks can be automatically stalled when debug buffers are fully loaded.
The HVD algorithms are used to automatically analyze and find out Basal Probes being the minimum subset of design signals that should be captured from hardware in order to provide full visibility. The greatest advantage of Dynamic Probes is that user does not have to know upfront which signals are required to diagnose given problem.
Instead, any design signal can be selected for debugging during emulation runtime. The HVD expands preserved basal signals assuring visibility of any design node. When debugging complex SoC it is required to check for different conditions to decide whether or not to capture debugging data. Triggers and Breakpoints bring intelligence and controllability to the debugging process.
The trigger, same as in logic analyzer, is used to release collected samples of static probes, whereas the breakpoint stops emulation clocks and returns control to the user. The conditions are either Boolean or sequence expressions with a complete set of relational operators. All triggers and breakpoint conditions can be enabled, disabled and reconfigured at runtime.
Memory blocks are present in any kind of digital circuit design. In SoCs they are used intensively not only as local data storage but often as key elements of the microprocessor sub-systems. Thus visibility of memory contents is essential for verification of both hardware and embedded software. Memory viewers are becoming first and foremost tools in hands of hardware and software developers. During emulation, given memory is selected by its hierarchical name as derived from RTL source code.
Physical address and the data organization are preserved in the user interface despite of actual FPGA implementation. Using the HES Debug API is a convenient way of developing powerful and interactive testbenches that can initialize on-chip memories, probe internal registers or even configure breakpoints dynamically. With this unique feature, the verification engineers not anymore have to treat design in emulation box as a black-box. Hardware Emulation Solutions. Emulation Debugging. Sign In.

In this tutorial, you will learn- What is Real Testing Device? What is Emulators? Testing on a real device allows you to run your mobile applications and checks its functionality. Real device Testing assures you that your application will work smoothly in customer handsets. What is Emulator? An emulator is a software program that allows your mobile to imitate the features of another computer or mobile software you want them to imitate by installing them to your computer or Mobile. A virtual device is not the real phone but a software which gives the same functionality as the real phone except a few functionality like the camera.

A compiler is a computer program or a set of programs that transforms the source code written in a programming language the source language into another computer language normally binary format. The most common reason for conversion is to create an executable program.
