Q:
- MOSIS design rules

A:
The Cadence tutorial manual has been updated this week. The new version
uses 0.5 micron technology, the old one 1.2 micron. Keep in mind that 0.5
micron process does NOT have p-base.

new: AMI0.5 - option code SCN3ME
old: AMI1.2 (AMI1.5) - option code SCNA

In addition to the manual use

under item 3: CIF and GDS Layer Specification with the option codes above.    


Q:
- How to print layouts from Cadence to a laser printer in Barton 120?

A:
First, save your layout as a .ps file as follows:
layout: Design/Plot/Submit/Plot Options select "Send Plot Only to File"
(for more details see class 491 Cadence manual)

Then use:
lp -dhp4000tn_1 <filename>

A:
As an alternative to the procedure described in the manual one can provide
a stimulus for circuit simulation from a file using "vpwlf" voltage source
from analogLib library. In PWL file name field one should specify the
ASCII stimulus file name. The file format is of two columns:
"time voltageValue"
For more info you can check Cadence help manual (search for vpwlf). 


Q:
guidelines below for HW2 submission.

A:
Create a new library named "<your last name>2" (As in example from hw1 -
smith2) in AMI1.2 micron technology. Name the top level cell "mult4bit"
(or rename if you have one already). It should contain schematic, layout
and extracted views. Please also include a printed copy (or send me a
pointer to) LVS/si.log file after you perform top-level LVS (this file
summarizes the results of LVS and by default is overwritten every time LVS
is run).

Also, please check to see that your library files (and home dir) have
"read" permission for other users (for me to access your files).              

Q: HW#1/d
- Problem 1.d

if your setup does not have a pin layer for Poly 2, you can connect your
poly 2 terminals with P2Con to Metal1 and then label Metal1 as your
terminal. 

Q:
- HW#1, problem 1 cell naming convention:

A:
1. Create 4 cells named: switch, horizontal, photo, CCD with layout cell
view ONLY for each of them.

2. Create a top-level cell named as follows: <lastname11> (the same as the
filename above but without an extension). In the layout cell view of this
cell instance four of your cells above in four quadrants placed as shown
below (do not interconnect them in any way):

switch   horizontal
photo    CCD

Make sure to check design rules for this cell.
NAMING CONVENTIONS are NECESSARY for your HW to be graded on time.
