Vision51 is a software simulator for most 8051-based MCU on the market. It provides functions
like Trace, Event trigger and Stack monitor functions that used to be available only on hardware emulator.
Its powerful debugging capability outperforms hardware emulator.
If Vision51 works with mProbe51(purchase product separately), Vision51 goes beyond plain software
simulation to emulate hardware I/O operation. This capability breaks limits on simulation and greatly enhances
the applicability of sotware simulator.
 

• FEATURE：
  • Imitate most enhance 8051 MCU.
  • Suppotr dual DPTR.
  • Use COM port to emulate UART of 8051。
• COMMUNICATION INTERFACE:
  • RS232
• EMULATION MEMORY:
  • 64KB Program/64KB Data with Optional extended bank function for hugeprogram.
  • Memory mapping With Internal/External attribute is supported.
• BREAKPOINTS:
  • Unlimitted breakpoints, program execution can be stopped, allowing the register and memory to be inspected and modified.
  • Hardware execution breakpoints can stop the program execution on exact instruction fetch cycle.
• IMITATE HARD WARE DEBUG FUNCTIONS:
  • 64 K the trace buffer for use to record all the signals on the microprocessor bus, including Address/Data/Control/External signals.
  • Combined with qualifiers, the traced data can be filtered. This allows you to select the required processor address, data, status or external signals while eliminating unwanted information.
  • Five events consist of a combination of address, data, control, match count and external signals. (Single, wildcard and range are supported.)
  • Five hardware levels for a sequential event trigger (IF-THEN-) with trace on/off or delay option (for trace operation). Each level can be set on OR/AND combinations.
  • Stack trace with Stack-Guard.
• Ｂank：
  • 256banks(64K X 256) program memory。
  • 256 banks external data (XDATA) memory。
     
• SOFTWARE SUPPORT: DEEMAX WUIT (WUIT-User Interface Tool For Windows)
  • Ten powerful windows: Command, Program, Register, Memory, Watch, Local, Browse, Trace, Stack, Status.
    The contents in Windows are update automaticaly and shown in RED color to remind users the data had been changed on the last operation.
  • All windows available for Docking/Floating and support Drag-Drop between windows. And they work intuitively and conveniently.
  • 'Command Guiding Bar' supports menu operation of All commands. It enables novices to use commands easily, whereas experienced engineers can use it to have a good command of WUIT swiftly.
  • Procedural statements lead development work into automation.
  • Smart download speed up code downloading.
  • To view program path by Call-Stack.
  • Support sole 'Debug Procedure' language. It used for automatic debugging.
  • Support High level debug(Keil C51 and IAR C51 compiler are available).
  • Instant tool tip supported by Program Window. Whenever the mouse cursor is moved to a variable (or a selected numeric expression), an instant tool tip will appear, showing the value of the variable or the numeric expression.
  • Work Space store/restore serialize your debugging job.

• Trial of Vision51：
  • Before buyingVision51 you can download software WUITSETUP (Vision51 trial edition inside).You can
    test and experience the function of Vision51.
