# awk script to replace sim2spice!
|
|
# Drew Wingard June, 1988
|
|
# modified by Peter Lim and Stefanos Sidiropoulos
|
|
#
|
|
# The awk script allows spice simulation of layout from Stanford BiCMOS
|
|
# Technology. To use this awk script,
|
|
# 1. generate a <block>.ext file from magic using ":ext"
|
|
# 2. run ext2sim to generate <block>.sim file
|
|
# 3. use sim2spi <block>.sim > <block>.spi to generate a spice deck.
|
|
# 4. edit the generate spice deck as needed
|
|
#
|
|
# In order to recognize bipolars the ext2simBiCMOS program should be used
|
|
# (this is no longer true --- Tim 10/10/97
|
|
# (modified by Tim Edwards for bipolar handling w/magic 6.5.1)
|
|
#
|
|
# Areas and perimeters are calculated if the right ext2sim version is used
