8051 Simulator simplifies code development with Micro C, BASCOM51 and Micro-IDE. Errors in user programs can be found and fixed quickly in simulation mode by avoiding time consuming downloads to the target board. Support for hardware ports in simulation. Use real I/O ports from your target boards while simulating the program on your PC.


  • Integrated Development Environment to edit, build, download, simulate and debug within the same program.
  • Simulation of 8051 programs in C, Assembly or mixed level.
  • Simulated program can be simultaneously viewed in C and Assembly.
  • Variable window to watch C variable names, values and addresses.
  • Register window to watch the simulated special function registers including 8051 ports.
  • Memory window to watch and modify up to 64K of simulated program memory or 256-byte internal RAM.
  • Callstack window to view list of function calls that lead to current program line ( traces all jumps and calls )
  • Terminal window to simulate 8051's serial port ( both receive and transmit are simulated )
  • Output Window Debug Tab to watch debug messages
  • Fully customizable window layout with dockable or floating debug windows.
  • Stop Debugging button to stop simulation at any point
  • Go button to start execution
  • Step Into and Step Over buttons to single-step through the source code at C or Assembly level
  • Unlimited number of breakpoints to stop execution at any C or Assembly source line.
  • Windows 2000/XP/Vista/7/10 compatible
  • Multi-file Editor to create and modify C or Assembly source code while simulating
