Powerful, yet easy to use and affordable 8051 simulator for Micro-IDE which is a Windows based Integrated Development Environment for micro-controllers.

• 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 95/98/ME, NT and 2000 compatible
• Multi-file Editor to create and modify C or Assembly source code while simulating
• Supports Micro C for 8051, SDCC, BASCOM51 and any standalone hex file.
• Support for plug-in's for peripheral simulation
