andrew , what iam saying is
I divided old technology schematics into two libraries 1.digital library 2. analog librarey
I want to change only old tech width , old tech length is converted to new tech length(instance of new tech length like 40nm)
Eg: old tech w=100n L=60n
new tech w=x n L=40n ===>x=(w of old tech*(2/3)) keeping W/L constant in old &new technologies
so finallay i want expression is
old tech width * (2/3) =new tech width
old tech length =new tech length ( automatic change instrance of new tech what ever you given code :procedure(fixIt1(inst parName val )
printf("Fixing %s on %s\n" parName inst~>name)
analog library: I want to chane length and width.
new tech width = old tech width * (3/4)
new tech length=old tech length * (1/sqrt(2))
Thanks for each quick replying of this issue.
Thanks in advance,
