Error while streaming in LEF file

[Brittoo]

Hi all

I get the following error while trying to stream in the LEF file:
"Constraint minSpacing does not match the referenced technology database:Cannot modify a read-only technology database.Technology information was ignored"

Anybody has any idea as to what needs to be done here?

Regards

I'd guess the minSpacing parameter of the LEF file isn't compatible with the min. (bondPad) spacing rule in your technology file (which can't be overwritten). Just make sure that both min. limits won't be violated.
