I used to import the standard library LEF file to create the
technology file of Abstract Generator.But when I created a hard
block's abstract view,some warning happened during the abstract
step.It said that the pin is off the Metal1_Metal2 Routing Grid. When
I ignored the warning and used the output doing Place & Routing,there
are many violations on Metal1 and Metal2,especially Metal2.
How can I define a proper metal pitch for the hard block?
I only have the layout view of the hard block.
