Here are some of the VMLAB user components that I have created. All components come with the C++/RC sources and the binary DLL files (compiled with VMLAB's usercomp.exe and the Borland BCC55 command line tool kit).

The components currently available are:

• AVR Studio Stimulus/Logger - Stimulus and Logging components that use the same format as the AVR Studio sim
• Verilog VCD Logger - Logging component that creates Verilog Value Change Dump format files.
• WAV Analog Stimulus/Logger - Analog stimulus and logging components that use WAV audio files.
• Break On Edge - Breakpoints the simulation on every rising edge of a signal.
  
• Digital Signal Delay - Digital buffer with user configurable propagation delays for rising and falling edges.
• COM Port Exchanger - Allows communication between VMLAB and a physical serial COM port.
• LED 7-Segment Display - A GUI component implementing a 7-segment display with decimal point.
• KS0108B Graphic LCD - A visual simulation of a KS0108B/HD61202 based 128x64 dot-matrix LCD panel.
• I²C 24xxx Serial EEPROM - Simulates generic I²C serial EEPROMs in the 24xxx series (e.g. 24C08, 24C512, etc)
• Performance Monitor - A GUI component to measure and display VMLAB's runtime performance.
• Digital Signal Display/Control - A pair of GUI components to easily display and control 8 digital signal pins.

• AVR Peripherals - Components to emulate the AVR peripherals found in the ATmega168 microcontroller.
  

Future Component Ideas

I have a number of ideas for new components that I could implement in the future. Unfortunately, I can only work on this in my spare time so many of these components will probably never get written. Of course, if anyone else reading this page wants to help, then please get in touch with me (see Contact section below); you would be more than welcome. At least two of these components, the MMC/SD card emulator and the NTSC/PAL video display emulator, would be much easier to implement if the VMLAB source code was released under the GPL, allowing me to re-use code from existing GPLed projects.

Source Code Repository

All of the source code for the above components is hosted in a Subversion repository on Google Code. Since I use this for all of my development, the "trunk" directory may contain unstable code. The repository can be either accessed online using a web browser, or offline by downloading the relevant code with a SVN client. Using a command line SVN client, you can checkout all of the code with:
