Download GSim85 8085 simulator Windows and Linux. GSim85 is an 8085 simulator. It is having very user friendly graphical user interface. GSim85 can be used to test 8085 programs before actually implementing them on target board.
GNUSim8085 is a graphical simulator, assembler and debugger for the Intel 8085 microprocessor in Linux and Windows. It is among the 20 winners of the FOSS India Awards announced on February, 2008.[1]GNUSim8085 was originally written by Sridhar Ratnakumar in fall 2003 when he realized that no proper simulators existed for Linux. Several patches, bug fixes and software packaging have been contributed by the GNUSim8085 community.[2]GNUSim8085 users are encouraged to contribute to the simulator through coding, documenting, testing, translating and porting the simulator.[3]
Master the 8085 operations in a digital environment creating customizable scenarios for performing test runs, practice editing and monitoring software and hardware behavior. The program features full graphical illustrations of all actions and generates bug reports.
8085 simulator was developed to work on Windows XP, Windows XP Professional, Windows Vista, Windows 7, Windows 8, Windows 10 or Windows 11 and is compatible with 32-bit systems. The actual developer of the software is Vaneet Singla. We recommend checking the downloaded files with any free antivirus.
The program lies within Development Tools, more precisely IDE. The most frequent installation filenames for the software include: 8085-main9.exe, 8085 Simulator.exe, 8085.exe, 8085simulatoride.exe and SIM51.EXE etc. ".85" is the extension this PC software can operate with. The most popular versions among the program users are 3.0, 2.0 and 1.6.
8085 Simulator has a very user friendly interface and the best part is, its FREE to download. You can master 8085 programming in matter of days now. full graphical illustration of the Microprocessor simulator. Salient features can be gauged as follows.
Microprocessor Simulator 8085 for Windows offers complete transparency at the register, flag and stack level. There's easy coding through a code key pad with complete input validation. It offers easy and extensive debugging including breakpoints and profiling options. Hex and Obj files are supported. The program also features an assembler text editor with syntax highlighting
Almost all Engineering students might have Microprocessors & Microcontrollers laboratory classes in the course of 4 year degree. So, one must know how to write programs and feed it into 8085 & 8051 kits to get proper output. Unfortunately, most of us won't have access to those trainer kits when we want. Here, simulators come for the rescue.
To work with the simulators which I'm going to recommend you in this post, you need to install 'Java Runtime Environment' as the simulators are built using Java. Download and install JRE using the link given. JRE for Windows users
First of all download the Java byte code of the simulator from the link - 8085 Simulator. Then, double click on the file downloaded. If you have a JRM installed machine, the simulator would have been opened. Now, you can start to work with your codes. Just follow some simple instructions given below.
The above image is the user interface of the simulator. At the bottom of this 8085 simulator topic, I would have written how to execute a program. First learn something about the interface of the simulator. It consists of 5 tabs. They are,
Unlike the 8085 simulator mentioned above, 8051 simulator is versatile and it comes with numerous peripheral devices like ADC, DAC, 7 Segment & LED displays, Matrix keyboard and Motor. Link - Download 8051 simulator
After downloading that .rar file from the link given, extract it. You would see a folder named, 'edsim51di'. Inside that folder, there would be a folder and a .jar file. Double click the .jar file to run the simulator. Keep the edsim51di folder as it is. Don't delete or move anything inside the folder.
Many simulators are available online to simulate 8085 & 8051. But, I find this two more useful as it is compatible with all operating systems and more versatile than many other simulators on Internet.
The Intel 8085 is an 8-bit microprocessor that was launched by Intel in 1977 and hence is something that we have never seen around. So why do we need to learn about the programming model and instruction set of this old microprocessor? The microprocessors we use are all for general-purpose computing but there are other applications of computers such as making automatic solar tracking-panels, automatic power-controls, or security control systems. For such applications, general-purpose CPUs are unnecessary-a waste of resources; a low powered CPU is what we need. The Intel 8085 is one of the candidates. To program this piece of hardware, we first need to know the programming model-the logical structure of the programmable registers, flags, and the instruction set.
The 8085 microprocessor simulator simulates the Intel 8085 programming model, with the same instructions available as on the real system. The input and the output of the actual machine and the simulator are identical, although the internal processing method may differ. The simulator lets you view the contents of the registers, the memory and I/O port values, execute one instruction at a time, and also write code in mnemonics instead of hand-assembled code. While I was pursuing my undergraduate course, I began to look for a FOSS-based 8085 simulator. Simulators supplied with text books, and others available on the Internet either did not fulfil my needs, or were not FOSS. Then I recalled that LFY had once published a review of GNUSim8085, and downloaded the software. The basic features listed on the official site are:
This simulator comes with an assembler: you write the code in Intel 8085 mnemonics, and it is converted to machine code by the assembler, freeing you from the pain of hand assembly. The assembler supports four types of syntax parts:
Instead of repeating the assembler features of the simulator here, I recommend you read the official site, where every detail is documented: -guide.html. From version 1.3.7, this assembler tutorial is included with the software, available at Help -> Assembler Tutorial.
This is essentially a very good simulator to work with for educational purposes. If you have to practice code for your college exam, or to test the code in the practical copies, then I would recommend this simulator. Some of my friends and I have used it during our undergraduate course, and had no problems. It has a very simple and clutter-free interface, an assembler, and the best part is that being under GPL 3 GPL2 or later license, you can see the code and even edit it if you like-or request any feature update from the developers. Programming in the simulator is easy, but it should be kept in mind that if you are doing a course, you need to handassemble and enter the code when presented with the actual 8085 in your college syllabus. It is good to make a habit of hand-assembling and directly entering code on the actual machine, to keep in touch.
Over last few years I (as primary UI maintainer) have deliberately avoided implementing some things in UI. Because I do not want to turn the simulator into IDE for 8085 assembly language. As it is my hands are full with all the bugs and enhancement requests. Hence there is no MDI interface, no configuration management and the printing implementation is very basic.
You have mentioned other good points from usability point of view. I will try to file bugs for them and get them fixed soon.
The motivation behind this review is that, in my opinion this is the only educational purpose 8085 simulator under GPL out there which is usable and good, and there no food reviews available about this software. Therefore i tried to write a comprehensive review highlighting both the positive and negative points and review unbiased. I have downloaded and used a lot of other simulators which i had to scrap as they were too flashy or were simply unusable.
This keyboard only interface is immensely useful and lightning fast when entering pre-assembled data, and keeps up the habit of hand assembly and entry. I have made a prototype and found that the interface is indeed useful. Therefore in later versions the GNUSim8085 team might like to consider such an interface.
a. Design a 8085/8086 simulator/assembler which supports macroprocessor using C language following the principle of Two pass Assembler.
b. Show how the generated object code is linked over different functions and show the functionality of loader over that with specific memory location.
The simulator supports all commonly used Instructions used in 8085 microprocessor. It also supports Macroprocessor operations using keyword macro. All numeric inputs are treated as Hexadecimal.
captureSnapshot : Stores the state (snapshot) of the simulator in a readable file for user reference. The file contains details of Registers, Flag Register, Mnenomics, Opcode and the Memory dump.
