3D Simulation
Part I . Generate mesh file.
- In the layout window(virtuoso editor)press F7 to bring up the MEMS menu function.
- Click on Layout -> Mesh. A Layout->Mesh Parameter Window will pop
up.
Input the desired L/W ratio and output filename. In this example, we set L/W ratio = 1 and
ouput filename = "try".
- Click OK. Watch the CIW window.
After Cadence runs for a while it will indicate that the output file generation is
complete.
The mesh file "try.unv" has been generated in your working directory.
Part II . Visualization in Memcad.
- Set up Memcad4.6 if you have not already done so. Click here for
instructions on how to set up Memcad4.6.
- In your Unix console window, start Memcad by typing
Memcad4 &
- A Memcad Main window will appear.
- Click on Device Creation. A Device Creation Window will
appear.
- Click the model button at the lower left corner, a Model
window will appear.
Fill in the path of the mesh.unv file we just created. Also fill in the locations and filenames
of *.mf1 and *.mbif files that Memcad is going to create.
- In the Device Creation Window click Convert Model. Sit
back and wait, the example takes about 20 minuites and 5Mb of afs space. When the
conversion is done, a window will pop up.
- Click Continue.
- Now in the Device Creation Window, click Model
Setup. Two windows will appear.
- In the Visualizer Control Panel window, click Start
Visualizer. The Visualizer window will appear.
- Now you can drag the viewer or click on the top viewer buttons to select different views.
Have fun!
