30 CHAPTER 1. INTRODUCTION TO THE ALLIANCE TOOLS
Table 1.7: Options Available for the COUGAR Tool.
Option Description
-t
Notifies a transistor level extraction, the symbolic layout cell is flattened to transistor layout
before extraction.
-f
The symbolic layout cell is flattened to the catalog level before extraction. Us e ”man catal”
for detail on the catalog file. If the catalog is empty, or doesn’t exist, the netlist is an
interconection of transistors, if it isn’t, the netlist is an interconection of gates or blocks
whose names are defined in the catalog.
-v
Verbose mode on. Each step of the extraction is displayed on the standard output, along
with some statistics.
-c
Generates a core file representing the conflictuel net, when COUGAR detects two external
connectors with different names on the same signal, or when it finds two external connectors
having the same name but not internally connected to the same net, or when it cannot
correctly extract an L shaped transistor.
-ac
Extract capacitance to ground on losig.
-ar
Extract interconnect resistance and capacitance to ground. Value of resistance foreach layer
can be changed in the RDS file.

This gives us a muxoop.ap file. We can visualize this file using the Alliance GRAAL tool. We call it from the
command line as graal and from its File menu we choose the muxoop.ap file. This is shown in Figure 1.12. We
