Lab 3: Getting Started with DRC, LVS, PEX

Step 2: If this is your first time running Calibre Interactive - PEX you will need to
create a new runset so just click Cancel. If you have run Calibre before find the previous
runset. This will simplify setting up Calibre.
Step 3: Begin by clicking the Rules button and setting the rule file and working
directory. The rule file should be of the form:
$ADK/technology/ic/process/ami05.calibre.rules
The Rules button should now be green.
Step 4: Next click the Inputs button. The Layout tab should already be set correctly.
Under the H-Cells tab, change the PEX x-cell file path to
$ADK/technology/adk.hcell.
Under "Netlist" tab, change the "Files" to be "MY_INV_netlist" that you generated.
Step 5: Now select the Outputs button. At the top, the Extraction Type should be
Transistor Level and you can choose one of the following types:
RCC - Distributed RC network with coupling capacitors
RC - Distributed RC network without coupling capacitors
C - Lumped net capacitance with coupling capacitors
Select the first one: Distributed RC + coupling caps
Step 6: In the Netlist tab you can setup the output format and file name. Choose DSPF as
the Format and Use Names From: LAYOUT. You should also see there is a name for
File: " MY_INV.pex.netlist ". You may change this file name to be
"MY_INV.pex.netlist_DSPF" for you to remember that the output file is a DSPF
format. Remember this output file name since you will need this output file for postlayout
simulation.
Step 7: Next choose Setup -> PEX Options from the menu bar. In the Netlist tab click
the Ground node name: check box and enter GND. In the LVS Options tab set
Recognize gates: to All. Also enter the following:
Power nets: VDD
Ground nets: GND
Step 8: You should now be all set to perform the extraction so click Run PEX. If a pop
up asks to overwrite the layout file click OK to ensure Calibre sees any recent changes to
your layout.
Step 9: When Calibre has completed the extraction a window will pop up showing the
top level of the extracted netlist. Notice that there may be up to two additional netlists
which will be included into the top level. The first will contain the RC networks and the
second will contain the coupling capacitors.
Step 10: Close IC station
