problems in parasitic capacitance extraction

[DTforwhat]

I noticed there's a rc file in test/Nangate45/Nangate45.rc I wonder how these Cap figures been calculated

@pradi001 set this up a long time ago. As there is no fab the numbers are somewhat arbitrary.

thx 4 reply!
I wonder what's the relationship between parasitic capacitance and the capacitance setting in this file
Does it get involved in parasitic capacitance extraction?
