Title: Calibre PEX/Config simulation error
Post by topquark on Aug 6^th, 2007, 2:43am

Hi folks,

I need to run a parasitic-extracted netlist simulation.
I ran Calibre PEX on the layout view of the top-level cell and on the sub-blocks inside the hierarchy, generated the 'calibre' views for all the blocks.
Then, I create a test bench schematic and config view to run my simulation.
When I use 'calibre' view for the top-level cell, the simulation runs with the full-extracted netlist.( the sub-blocks inside top-level cell automatically are instantiated as 'calibre' views I believe)
Now, I need to use block-by-block extratced views to see which block is adding critical parasitics.
So, I turn on 'schematic' view for ther top-level cell and try to use 'calibre' view for one of the sub-blocks.

I get error during netlist generation:

here's the attached snapshot of the error

NOTE: I have DRC/LVS clean sub-block cell views and symbols match schematic in pins, wonder why pins are not being recognized during netlisting.

Ok, I just figured it out -
it's a trivial case of naming the pins in schematic in lower case >:(

So, Calibre recognizes the pins only in upper case!

oops! my whole database needs to reflect this change now!
