Key Steps in Using Magic

Some notation: LC, MC, RC = left, middle, right click of mouse buttons; <= = enter = return

Some useful commands within MAGIC ( : is used on and to go to the command line in the control window while others are within the draw window)

a = select area b = box coordinates c = copy

g = grid and ungrid o = open and close window :q<= = quit MAGIC

s = select block u = undo U= redo

x = expand X = unexpand z = zoom Z = unzoom

. = redo last command :load <file> :move <direction><distance> or use LC in box

:getcell <file> [can’t easily edit] :dump <file> [can easily edit]

:label <text> [inserts @ box top] :erase label [select label box first] :move [selected box to cursor]

:what [gives layers selected]

Some useful commands of UNIX; pwd <= = display working directory cd .. <= = return to previous directory ls <= = list files cp <= = copy cd <= = return to home directory

Major Steps in Magic

1. After logon to a EE Department UNIX machine, cd <directory where desire files> <=

2. tap magic <= = (creates a MAGIC control window)

3. magic <file> <= = (creates the file <file>.mag and runs magic in a MAGIC draw window which appears after some wait and on LC) (shows technology file used and magic version = 6.x)

[alternate: magic <= = then :cif read <file> or if need a flattened cif file use :cif flat <file>]

4. :open palette <= (or better palette_09_06_95) (displays the palette and layout symbols to click on for making the layout use RC on lower left to enlarge, MC on a color to transfer a color)

5. Resize the screen as desired by LC on the upper right resize box.

6. Make the layout as desired

a. space bar changes tools among

box [cursor = cross] (use for devices)

netlist [cursor = square]

wiring [cursor = up arrow] (use for connections)

b. to make a box: LC on lower left corner and RC on upper right

MC on color desired to fill in the box (dots=drc error)

MC on blank to erase

c. to insert sublayout files, put left bottom corner of the selecting box where desire and type

:getcell <file> <= = ; to expand this sublayout put selecting box around and

type x

d. if need pads use :getcell <pad-file> (some magic pad files=40pc22a_pad or 40pc22x22 or 40protected_pad) then :expand

7. :drc find <= = design rule checker; :drc why <= = error reason

8. :ext <= = creates the extract <file>.ext for simulations (add <style> where style is lambda=<L> where L=0.6, 0.8, 1.0, 1.6 with default = 1.0

9. :cif <= = creates <file>.cif for graphics and MOSIS fabrications;

for 1.6u first do :cif ostyle lambda=0.8(gen) which sets default of 0.8 needed for fabrication

10. :save <= = save and then :q <= = quit to exit MAGIC

The following is outside of the MAGIC draw window (use Ctrl-z or q) but in the MAGIC control window

11. ext2spice <file> <= = (uses <file>.ext to give <file>.spice)

12. To print, if saved a <file>.cif use cif2ps <file>.cif <file>.ps <= then print as a postscript file

via qpr -q <printer>-ps <file>.ps

13. exit machine with logout <= =

Notes: 1. MAGIC is in ~cad/bin; tutorials are in ~cad/lib/magic/tutorial

2. Tutorials 1 & 2 (of 09/19/90) and scalable technology manual of MOSIS (09/08/89) are the most important at the start

3. For design rule checker rules see Tutorial (of 09/19/90) #6, p. 2.
