Welcome to Rans & Anks Software

    About us - We are freelance software developers based in India. Currently we have launched ourselves with one educational product -  µP-Sim. Very soon we will be coming out with some more good utilities to make everybody's life simpler. Please do visit us later sometime to look for some more utilities. Do mail us if you have any queries.

    µP-Sim - The 8085 Microprocessor Simulator (not just any other 8085 simulator) is a total software solution to replace the microprocessor kit or the in-Circuit Emulator from training and design labs. The Simulator executes the instructions from the user entered program, instruction by instruction showing all the register and flag status at the end of execution of each instruction.  The input process is fast and efficient, leading to better productivity. The Mnemonic Pad allows the user to enter the code. This makes is impossible to enter a wrong Mnemonic. The Tool tips tell you the syntax along with the operation performed by a particular Mnemonic.

    The Data Entry Window allows you to enter the Data Segment of your code. This is provided to enable the user to enter the data once and save it along with the code. On selecting the Data Entry Window from the Menu, the Mnemonic Pad displays only the Hex Key Pad. This can be used to enter the Data.
 

Specific Features

• Absolute Transparency in functioning of the Microprocessor at Register and Flag levels.
• Constantly displays the contents of all the memory locations that are relevant to a program.
• Mnemonic Pad based fast and error proof code entry system which saves a great amount of time and effort.
• Indispensably useful for Learning and Teaching purposes.
• Makes writing machine code programs really easy because in this Simulator you just click at buttons for the mnemonics and everything else is done automatically.
• Extensive and user friendly Debugging facilities.
• Shows all Stack Activities distinctly and even permits the user to inspect the Stack Area of the memory dynamically at run time.
• The user can test his programs for efficiency in terms of clock states, machine cycles as they are dynamically updated during runtime.
• The entire 64 kilobyte memory space is available for use, though the user is allowed to choose his own Start Address.

Why the 8085 Simulator ?

    The 8085 Microprocessor is the basic microprocessor taught to students first all over the world. The concepts of how microprocessor can be well understood in this basic chip. The same concepts can be very easily extended to advanced processors like the 8086, 80286, 80386, 80486 or the Pentium processor. Since 8085 is the most easiest to learn so you must learn the 8085 first.

    Today, students write their code in machine code in a Microprocessor kit which is a piece of hardware with keys that very often develop key debounce problems. After an hour of painful machine code entry the program is executed and the student is left clue less about where his problem just went on an infinite loop. Since he can not save his program he goes home for the day and goes over the entire exercise again the next day. It just steals away the fun from the Microprocessors.

    In this simulator all that is History. He just clicks on the mnemonics and the machine code is written for him. Then he can debug the program by executing Step by Step. All the register states, flag states, memory dump, I/O Dump, Stack Locations, M/c Cycle and T-States taken, are clearly shown in a tabular fashion at the completion of each instruction.

    The Simulator also supports the step running as well as full running mode. You can even select the execution speed from the menu.
