MOS transistor, capacitor and resistor generators contributed by Don Rogge

Dear ICED User:

These cell generators were contributed by Don Rogge. The .CMD files have been carefully documented so that you can modify them to work with your process. They should extremely useful in analog layout and also serve as examples to users who want to learn the ICED command language.

The generators can automatically construct capacitors, resistors, and CMOS transistors of a value you input, e.g. you can tell a resistor generator to create a 500 ohm resistor. Each generator consists of a .CMD file and an associated .CEL file which must be copied into appropriate directories. The .CMD files work by prompting you for one or more values and then creating a temporary cell, based on the associated .CEL file. The .CMD file then allows you to place the temporary cell which is automatically ungrouped.

The following steps may serve to help you familiarize yourself with the generators:

  1. Create a new directory, say C:\ICED\ROGGE.
  2. Copy GENERATE.ZIP into the new directory and unzip it.
  3. IF YOU ARE USING THE BETA TEST ICED FOR WINDOWS: type
    4.      DEL2CEL

    to rename the

         @2E92QUI.DEL -> M1M2ACT_CNT.CEL.
  4. ******* READ DON ROGEE'S DOCUMENTATION (GENERATE.TXT) *******
  5. Open a new cell in the new directory and try the various .CMD files.
  6. Load Don Rogee's layer names by typing:
    7.      @NEWCELLS.CMD
  7. Play around with the .CMD files. (If you use the @%.cmd menu entry you will probably have to select NextPath one or more times before the command files apear.)
  8. If you plan to use the generators, you will have to modify the .CMD and .CEL files for your process. I suggest placing the modified .CMD files in your AUXIL directory (usually, C:\ICED\AUXIL). You will also have to modify the .CEL files. The modified .CEL files must be placed in a directory on your ICED_PATH.
