Demonstration of (1) extraction of a random counter circuit
and (2) switch-level simulation of the circuit.

STEPS
=====

1.  Make project, use scmos_n technology and lambda = 0.2 (micron)
    % mkpr -p scmos_n -l 0.2 projectname

Rest assumes that you and your files are in the project directory.

2.  Use cgi to put crand layout into the database.
    % cgi crand.gds

3.  Perform a flat extraction of cell crand, also extract ground 
    capacitances.
    % space -vFc crand

4.  Start simeye.
    % simeye &
    Type "crand" in the rectangle below "cell:".
    Inspect the input signals by clicking button "input".
    Click button "ready" to leave the input mode.

5.  Click button "sls-timing" and put the "A/D" switch to the right
    of "sls-timing" in mode "A"
    Perform a switch-level timing simulation by clicking button
    "run" and watch the simulation results.
