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.
